With so many people asking about this lovely air shotgun ( actually co2 ) I thought it would be nice if I could gather my experience on one spot. I have owned mine for 5 years know and it was not until recently that I found out some forums and on these they were asking a lot of questions.  I have now collected a lot of major questions and answers along with my own experience. The Trapmaster were made between 1968-71, and even today more then 35 years later you can still find an example that will hold co2 and shoot like a queen. Trapmaster was sold in a box containing both a clay launcher, table, clays, reloading box etc. It was introduced to the market as a training tool.  Additional reading can be found in Airgun Digest 3rd edition, US Airgun Magazine Jan/Feb/Mar 1995,  just to name a few.

15/8-07 Look at this link to see real close what a Trapmaster with a 80 grain roundball is capable of.

Many thanks Bill.

21/6 2007 Picture added Ron Sauls, And his  Crosman 1100 .25 caliber gun.

15/6 2007  More custom work from Peter, adding a nice grey paint that really puts the 1100 to a different level.

6/5 2007 More pictures added - Among them are a new creation from Peter Ruut a very nice one. Also a wood woork from a Remington 1100.


Also new pictures, original box, added to the library ( see the end of this page)

Along with the plastic valve, I changed the spring to a stronger one. With trial and error I changed the position of the power selector. This is a delicate work, to much pressure and the valve can’t hold the hammer, to loose and I loose power. I have been thinking of putting the original spring back, and this day I had some time over. I stripped the gun down, but before changing the spring I tried to tighten the power selector. This made the valve to letting co2 escape, there was too much pressure on the valve after firing one shot. With selector at position as before I put the original spring back in and filed the gun up.

   The Trapmaster is a little bit itchy before settling down. I tried a numbers of filling, and the best I got was 11, don’t let this number fool you because this was the hardest hitting H & N .378 round ball I so far shoot.

With 490 fps and 80 grains/5 gram this is 42 ft-Ibs. This fill must have been a magic one, tried a few more but did never come close to this speed. All test was indoors  at around 22 Celsius.

I cant wait to see what a warm day outside can produce.


When doing the changes I had opportunity to weigh the valve, the original made of brass was a heavy hitter of 32 grams, and the baby plastic only 6 grams. All the difference in speed  is the delicate tuning between the power of the hammer, stronger/weaker spring in the body valve, weight of the valve etc. More testing will be undertaken, but the figures that is written in numerous airgun books, magazines, saying that the Trapmaster can produce around 600-650, ( with a heavy load of around 80 grains) is far from what I have achieved so far.

Measure speed is one thing, but when you can see the difference in a splatted ball its more dramatic. At top shows several .375 Hornady round balls shoot at a steel plate at 465 fps, the diameter is 2,5 cm and 2 mm thin. As I said before I got 490 with a H & N .378, this shoot was the only at this speed, and I did not shoot at a steel plate. The highest speed on the shoot is 495 fps this is a 73 grains load.

 If any of you out there have idée to gain more power plz let me know. 



This shows the fastest speed so far for a standard shoot load 73 grains.


Wow when doing the measurement I saw that the power had gone up!

Hornady .375

Upper row shows the powreout put so far, the one’s under was before changing back to the original spring.



First of all I would like to thank Jim Kramer from the US, for sending me these nice slugs.

The figures shown was before I changed back the original spring. New tests will come soon.

Also figures and patterns of the intended role as a shotgun. These test has to be done outside at longer ranges, and of course the days must be wormer. The most efficient slug of these so far is the both lightest and smallest in length. Accuracy test is planned when the sun says hello!. So far


509 fps/4,15 gram

438 fps/ 6,25 gram whole base in bottom

446 fps 5,13 gram

396 fps 6,5 gram

388 fps 6,84 gram

328 fps 8,97 gram



Here you have some nice slugs with different weight’s and length. With a flat area in front these send some chockwaves.


Only one is solid in the base, more testing is on the way.






I did some more shooting and here are the results so far.

Hornady roundball .375 with plastic wad 439 fps. This is 34 ft-Ibs


Handler & Natherman .378 with plastic wad 447 fps. This shoot is the only one that got clean trough a 1,5 mm thick aluminium plate. This shoot was a 35 ft-Ibs


Steel ball .375, 478 fps. Weight 55 grains/3,5 gram. This one did not penetrate the aluminium plate. 27 ft-Ibs.


To the smaller homemade bullets I got impressive 595 fps with a crow magnum with a weight of 42 grains/ 2,7 gram. 33 ft-Ibs


With a steel arrow to blowguns I got 599 fps, 26 ft-Ibs weight 33 grains, 2,1 gram.


Aluminium plate 1,5 mm thick

Here is the entrance hole from a .378 H&N roundball

going in 447 fps.

And got out on thsi side, strangley this was the only shoot that got clean through.

Homemade ammo

Made some ammo with melt candle and some diabolos.

New projectiles to Trapmaster can bee seen here. I made a mould to fit the .380 bore and put both .177, .22, .25, and blow darts arrow. I will do some testing with these. More to come


Mold metal

This one I made to make lead bullets, but tested to do some of candles.I must say even if they are made of candles the bullets are no toys. Then i put a .25 Crow magnum in the middle.

Mold plastic

Not to use with lead so why not do the mould in hard plastic.

Mold open

This one i drilled hole for each cal, then the bore of the Trapmaster .380. These will be right in the middle.



I finally got my hands on a Chronograph and did some indoor testing.

The .375 Hornady round ball left the barrel of about 400-406 fp/s. Nest the H&N r.378 round ball went up to 423-425 fps. The ball weight is around 80 Grains.  And so far I have managed to get out 31 ft-Ibs. Seems that the larger .378 is tighter and not letting any co2 escape.

 With standard shoot load 73 grains the speed reached 445 fps. And this equal to 32 ft-Ibs. All the test was indoor, at around  22 degrees Celsius. When summer comes with the hot weather I will do some more testing. The goal is to take the Trapmaster up to 500 fps with a 80 grain round ball. So far I have files the sear and changed the valve to a plastic one. I plan to change back the original spring, this one is much weaker and should do good. The fill of 32 gram co2 was enough for 16 shoots, this means that 2 gram of pure co2 is used for each shoot. Before the mod only 1 gram was used.



Pictures of Trev´s .22 Trapmaster added 22/2-2007



New pictures added of a Goldplated version- Only six of these gold-plated 1100 models were ever made by Crosman. Stuff like this came out of the prototype/model shop. By DT Fletcher 21/2-2007



More info of the rifled 7 mm barreled version of the now famous Trapmaster- New pictures added at the bottom 21/2- 2007


Lists Item No. 1370 as:

"Crosman 1100 custom built 7mm CO2 rifle. Rebuilt by advanced airgun hobbyist-machinist. Fitted with 7mm high power rifle barrel with ventilated rib, open iron sights, ramp front sight. All metal and woodwork excellent except custom barrel has not received it's final polish and bluing. Complete with Lee 7mm round ball bullet mold and 10 beautiful, lathe built, heavy brass cartridge tubes which each accept a 7mm lead ball. A high power delight. US$139.50"

The year for this is suppose to be 1980. Only a few was made

Also info of a .22 version- Sharp inventor and designer, Kensuke Chiba.He had a great interest in the workings of Crosman guns-in fact he was the first bloke to put a .22 barrel on an 1100. The original barrel was shortened and an insert was fitted. In it,a stout washer has been fitted to the CO2 port so you simply load into the breech-end of the barrel,close it against the port seal and fire.The ejector mechanism has been removed-not necessary. This text was taken from Crosman/Vintage forum and was written by Trevor Adams.


With the set that was for sale in the late 1968 you find a skeet trap, some “clays” made of plastic and different colours of shoot shells. A metal box in the package included a “loading” tool, size #4 #6 #8 of lead balls and plastic wads. A very great addition to your Trapmaster. 17/2 2007


Skeet trap

Here you have the whole set for a very nice day of clay shooting.


The box that contain goodies.


Oh a lovely colour mass. The reason why the shells is in various colour is that you can load them with different size of shoot. The white bag is the plastic wads.

All accessories

Here is the box with the plastic clays, shootshells, manual, co2 bulbs.

Well you have to have the manual to this co2 shotgun/big bore 16/2 2007  Manual


The Trapmaster co2 bulk-fill- the end ( 9/2 2007)

Finally I got my Trapmaster to work with a bulk-fill as it did with bulbs. But it has been a long way to go with a lot of trial and error. The first thing was to get a large bottle of co2, not the easiest way were I live it seemed, but I got one. Next steep was to get a connection to my paintball bottle, this was no trouble. Finally to fill the paintball bottle you have to cool it down, if you leave it in the freezer for about 30 min you should be able to get a complete fill. In this case a 20 oz bottle should way 926 gram empty, and a complete fill 1486 gram a difference of 560 gram of pure co2 This is 28 gram per 1 oz. Total 20 oz equals 560 gram co2. With the paintball on a scale while filling its very easy, and no chance of overfilling. The trouble for me started when I wanted to fill the Trapmaster, it seems that it has too bee a fill of around 24 gram. At this amount of co2 the Trapmaster seems to work best. It seemed that I was not able to get a complete fill, (at the end before I managed to get the larger bottle I was only getting gas and no liquid from the paintball) I managed to fill between 12 to 16 gram, but this was not enough to withstand more then one or two shoots, these were not as powerful as before. This I think has to do with the power selector that is on high and the tension is real hard, therefore the hammer has more power on the valve. Seems it’s a delicate thing to have the right pressure to the power selector versus the spring in the valve.  I cooled the Trapmaster down simply by putting it outside, and I managed to get a good fill of 27 gram, I waited two hours and then shoot but the .375 did not flatten as well with two bulbs.

It seemed that 2 hours was not enough to warm up the Trapmaster. Then I managed to destroy the threads on the adapter so when trying to fill co2 escaped. I cut the bad  threads, but missed a sharp edge this opened up the rubber in the fill cap. When filling a lot of co2 escaped and no good fill. Simply by putting a o-ring between the paintball bottle and the fill cap solved this. And today 9 February 2007 I fixed all this and filled the Trapmaster with the highest amount of co2 so far 32 grams. And after I test shoot it on a steel plate there seems to be the same result as with bulbs. Note also that I have the new plastic valve in, with a chronograph I should know if there is any increase of speed. This could be so small that it won’t show up on the splated round balls. Se the splatology by Tom Gaylord  http://www.airgunwriter.com/splatology.html  But for now I am glad that I managed to get them splated like before with the bulbs. A impressive 2,2-2,3 cm in diameter, and only 2,5 mm thick. This is near the same to a Swedish Krona.  Would like to thank all that has contributed with idée’s when I was asking a lot of this on different forum. And as always I would like to hear from other Trapmaster owners and shooters of their experience and results.


Co2 bottles

Well here is my whole setup included some of the shoots taken after i got my complete fill of 32 grams co2.


From the left a Hornady .375 roundball, second the same ball after hitting a steelplate, and to comparison a Swedish krona.



Bulkfillling the Trapmaster

Finally i got my hands on a large co2 bottle. With this I can fill up my paintball 20 oz bottle. So far so good.

To get a good fill from the paintball tank to the Trapmaster you have to cool down the Trap. I did this simply by put the trap outside in the cold. For the first time I got a very good fill 27 gram. When using bulbs you get 24 gram. But still with the same and over the amount the Trapmaster lacks the power that I am getting from 2, 12 grams bulbs. I have tried in many ways to fill but its still shoots the hardest with bulbs. I think the smaller bulbs have some gain in power. Any advice, idée’s is more then welcomed.


Co2 equipment

All you need to make the Trapmaster a co2 eater, if i only could get the same power like with bulbs.


Here is a step to step info on how to replace a valve. Before this mod i have changed the spring to a harder one, inside the valve, the spring guide was removed, and the sear has been cut. This to prevent the hammer strike on it, therefore more power because the valve keeps open longer. The stronger spring I put in the valve, was not a good idée ( if harder the less time the valve will keep open, but whit the original spring it was to soft to hold against the tension of the power selector), but I have balanced the harder spring whit the power selector. I had to open it up once again to change the original spring.  Due to lack of co2 I will update the shoot testing in the future. Click on pictures below to make them larger, under each picture their is additional text.



Crosman 1100 Trapmaster

First step is to make sure its unloaded and that all the co2 is gone. Then unscrew the end cap, otherwise you can’t get the for end of. Then unscrew the back cap to the stock, inside it’s a long bolt that is loosen and the stock can now be removed.

Round balls

These roundballs, Hornady .375, H&N .378 were shoot at a steel plate at distance of 5 meters.

Shoot shells

Aluminium shell along with the plastic ones. One advance with the transparent one is that you can see whats inside.

Hornady .375

Shoots taken on a steelplate, with standard bulbs.

A total of 24 useful shoots, with standard valve.

Modification, the sear grined, and harder spring in valve.

As you know I am a great fan of the Crosman 1100 Trapmaster and have been testing a lot of different ammo such as round balls, slug, and size of shot. Also modification to press some more fps out. Shooting with red dot sight at fair long distance. I have used the smaller co2 bulbs (12 gram) and got out 24 shots on high power. With a large co2 bottle that I fill the Trapmastern with, I can not get as many shoots, its very tricky to get a proper bulk fill. The Trapmaster is very sensitive.

To my point I shoot .375 balls on a steel plate and these flatten real good, then I shot .378 balls at the same distance and speed, but they came out differently. It must be that the led components is different and that the .375 are much more softer then the .378.

The .375 is 2,3 cm all around these are more equally flatten
The .378 is between 18,5 to 2 cm.

We have all read the splatlogy of Gary Barnes, this show that you can fairly se which speed a bullet/round ball have when you se how much its flatten, but as you se of my test this can vary depending on the hardness /softness of the ball.

Well, once again I have tried to hot up my Trapmaster, this time I took it apart and put a file to the sear, I have done this before but I took of a little bit more this time. When finished I filled it up with the bulkfill, whoomp the 80 grain (5gram) .375 round ball from Hornady hit the steel plate, hmm the ball was not that all flatten as it use to be. Shot number two ventilated all the co2. Hmm i thought I had cut a little to much, I tried to loser the tension of the hammer spring, put the power selection on low, but nothing worked. I was getting a bit frustrated, think,think, what has happened? I took It apart 3 times testing different theories. But still the #”¤%& co2 escaped like a fart in the wind. Finally I tried the smaller bulbs (12 gram) and the gun shoot like a dream. I am not so familiar with the bulkfill, but it seemed that it was only gas left.

Hunting with the Trapmaster, with the .375 .378 round ball these will take hare and even fox up to about 20 meters or so and anything smaller.

When we come to the shoots, it’s a different story.
If we take plastic shell 2 cm in length with the plastic wad at the rear, and a 3 mm cork at the other end, I can fill it with 20 3,5 mm lead shoot ( about 80 grain/ 5 gram) With number #6, 2,75 mm and 30 of them 57 grain/3,5 gram. In a aluminum shell 2,3 cm in length I can get 30, 3,5 mm shoots, I get 120 grain/7,5 gram. With #6 (2,75) I get 40, 76 grain/ 4,8 gram.

I don’t have any way to measure the speed of my Trapmaster, even though this is modded and do a little more then a standard one, we still calculate with around 400 fps/120 m/s.
If we take the red shell with 20 3,5 mm, we get 27 foot-pound/36 Joule, and with the #6 shoots we get around 16 foot-pound/ 22 Joule. I we take the aluminum shells we now get 38 foot-pound/ 51 Joule, and with the #6 we get 27 foot-pound/36 Joule. Note these figures are as close I can get and vary a little up and down. Conclusion if you managed to keep the shoots in a fairly close circle at 12-15 meters it has the power to drop dove, rat, mice, jackdaw, magpie, and other quarry at these sizes With winter around the corner and co2 don’t like the cold you have to wait to the summer for more testing, with shoots at these distances.

Below a few questions that I have asked on forums and with answers that followed.


Finally i got my connection and paintball tank to hook up on my Trapmaster. I have changed the spring in the valve and filed the sear , but no sine of increasing power. The thing with the paintball attached is that on high power shooting, the valves don’t close, i have to manually push the "hammer" forward, this don’t exist when the hose and paintball is disconnected. Anyone know why? On low power the .375 round balls is flatten out to 2 cm, and the thickness is around 3 mm. On high power they flatten to 2,2 cm and ca 2,2 mm thick. As you can see the deferens is not that high. I do not have a chronograph so i don’t no the velocity, but these figures was done before modding, and the velocity for a standard Trapmaster is around 400 fps/ around 120 m/s. These figures are the same after the "modding", and the hose and paintball tank attached.
All shoots take from around 5 m on a steel plate. Also the best material to use on the shells is cork, just buy some cork and a cutter in 10 mm, and you have perfectly round wads to use on the shoot shells.
If you have modded the Trapmaster in another way and gained a higher velocity, plz let me know. also other stuff.


If it solves the problem, then you know to try different length and power springs, until you find one that adds power without losing function.

To add power, you need to add airflow to the shell.
you should angle the port and smooth off all surfaces that the co2 passes over from the valve to the shell.
Also remove any mass inside the valve that is unnecessary without losing strength.( co2 is not as strong as PCP but can still be dangerous.) this will increase the volume of the valve and in turn add power to the gun.

The valve opens for set distance for a preset time.
(not easily changeable) so the only way to add airflow (co2 flow)is to increase the opening that the gas flows through, "Porting"

Good luck with your mods. I hope this helped.
( I am Fairly new to modding myself so If anyone has more to add, or disagrees with me, Please add your comments.)



Se my other inlay on Trapmaster below.
I filled up my trapmaster with no problem yesterday, but to hook of the hose, i had to unscrew the top witch are connected with the paintball tank, because when the hose was hooked up, and the on/off valve closed, and for that thing open, it seemed that it did not had the pressure to keep my valve closed on high power. I therefore unscrewed the connector to the paintball tank, and let the co2 escape inside the hose and i was able to hook of the hose from the rifle. I could now shoot without the paintball/hose attached. I tried this again today, and co2 got away all over the place, the o-ring was busted, i replaced it, but could not unhook the hose to the rifle without that co2 escaped. It seems that if i want to fill up my rifle this way without to have it attracted to my paintball tank i have to live whit the fact that some co2 escapes, ( the co2 still in the hose, when the paintball bottle is off) the pressure in it make it impossible to disconnect the hose from the rifle. I will order a connector that don’t use a hose, this one is attached directly to my adapter.
If any has a ide plz mail


If i understood correctly pressure in the hose is making it impossible to disconnect...in that case it seems like you need a bleed valve to drain the hose.


I have a Crosman Trapmaster 1100 shotgun, and using 2 powerlets. I tested too use only one, and the power dropped, i thought that the pressure was the same with one or two powerlets, and that more then one just gave more shoot and not more power.

I will put on a hose and fill from a paintball tank, the question is now if i do this, does the power increase also. And if i shoot with the hose attached would this high the pressure even more?


is that there is less pre-warmed gas available for the shot, Yes hooking up the paint ball bottle should give a little bit better performance than shooting with two carts, for the same reason, more pre-warmed gas for the shot. HTH. james


I bought a adapter from USA and i cant find any connections to fit to the adapter, with a hose to a co2 tank, so i can fill up my Crosman 1100 Trapmaster.
If anyone could help me plz mail or write Looking for connection from adapter with a hose to a Co2 tube.


The right connector is threaded 1/8 NPT. I just received a complete bulk fill kit from one of the forum members (JimC) today. It included a 1/8 NPT QD coupling a high pressure coiled hose and an adapter for my paintball tank all intended for bulking my QB-78. He even took the effort sending it over to Europe (Netherlands).
He told me he had a few more sets and he's very reasonable with prices. Drop me an email as I don't want to post his email address on the forum.

This I asked on forums

just pumped 1500 psi into my Qb78 and everything worked fine, and i wonder if there is anyone who have tried to fill the Crosman 1100 Trapmaster with air at around these pressures. With so many of you out there experimenting with this plz comment. Is it safe?.
Merry Christmas and were is the SNOW!!!!!!!!!!!!!!!!

here are some answers

Hi Kenfi,

excellent the QB78 works great with HPA.

If you're going to experiment the CR1100, perhaps you should start
at 1000 psi or 1200 psi first before going any further.

the valve in the 1100 is big ,you may not get any better speed with hpa . i would think 1000-1400 psi should be ok ( never tried it myself ) but the higher the air pressure the heavier the spring must be . make sure the copper tubing is not jam'd or rotted anywhere .

This i tested

Thanks for the comments guys.

I tested to pressure the Trapmaster to 1400 psi/90 bar but as you see this valve was not constructed to be use on air. But if any of you have any ides to get it working plz let me know. Its a lot easier/ and economically for me to pump up the gun with pure air

See picture how it turned out

Co2 vs Air

Well here you cleraly see the diffrent beetwen co2/air

The Trapmaster is not constructed to use high pressure air.

Here are some ammunition in form of round balls, and shoots.

Roundball .378

The plastic bags contain 200 .378 balls from Handler & Natherman. I have noticed that these are a bit harder then the Hornady.

Roundball .375

These are .375 balls from Hornady. I have noticed that these are a bit softer then the H&N.

Wads, plastic, aluminum, balls, shoot

Here you see the wads that goes in front. Plastic and aluminum shells wich are a bit bigger.

Shootshells in original

To the left you have a new produced shell from PHOXX Mfg, the red box is a original from Crosman.


Alternative ammunition

Steel balls Steel Arrows

I’m not recommending any of these; both can be very dangerous due to ricochets. Of the little test i have done the steel arrow is not very accurate. Only shoot a couple of the steel balls and they did have poor penetrating power, these ways 3 gram, the same ball but of lead ways 5 gram.


Here are some test shoots taken during last summer.

Hornady .375

Here are some recovered balls; these were shoot from a distance of 30 meters on a steel plate.


Captive sended me these pictures of his modified Trapmaster, very nice 9/2-2011

The Trapmaster above looks good, but looks even better below after modification


Modified a 12g stock to fit my trapmaster. Made the forearm pump action too. Barrel is locked to the forearm so you just need to slide the forearm back, rather than the barrel.

From Target  man Canadian airgun Forum added 2/2 2011

Hunting with the Trapmaster and using shoots is what Target man has done.

He took the grouse with no 7 shot, and used bb´s for the rabbit. The shell was filled up with 9 bb´s and shoot taken from 10 yards.


 The white rabbit was taken

 with the 80 grains rounds ball, a body shot ,and dead Immediately on place no jump.

He also put on a b-square mount see what has to tell about that below

I finaly put a sight on the b-square mount,
i have try a smal 3x9x42 scope ,it was very nice balance look ,
but the small scope was to complicate to aim in good position ,
i have try that hollowsight ,
its much less nice but so easy to aim whit ,
i zero it at 20 yard ,and can easy shoot at 25 yard whit no aiming change,
this hollow sight use 2x AAA batteries ,very useful,

He also has used air insted of co2 when shooting




He is also casting his on bullets



He also has done his own wads and used plastic to see what shoot it containded.

Here the way i make my wads
i take a 3/8 punch,
i take the most compress cartrige possible
i put a minimum of 1/4 inch for bullets





Below by unknown,( picture found on internet) has used the trapmaster to take out some rats.



Here are a few modified Trapmaster along with accessories.


Crosman 1100 Trapmaster

Bulk fill with a hose, the barell seems to been shortend
