I'm new to pistol airgunning, so I'll probably have a number of questions in the next few weeks. Here's are my first few.
How many shots can I expect to get from a 12g cartridge in a 2240?
Do the cartridges leak air when they're partly used and in the pistol overnight?
Does performance drop off as the cartridge empties? If so, after how many rounds do you normally see a drop off?
When you shoot fairly rapidly, the cartridge tube gets colder. Does this cause the pressure to decrease? I noticed a drop off in elevation after about 25 rounds fired fairly close together. It seemed to come back after I let the pistol shoot for a couple of minutes.
That'll do for now. :)
i havent done a round count yet
the co2 does not leak out i have had the same cart in my gun for a week now poa/poi still the same
after x number of shots the poi changes then the cart gets low
when my poa/poi changes i change my cart
I'd estimate around 40 shots from a 2240. I'd suggest putting a drop of Pellgun oil on the seal of the CO2 canister occasionally to prevent leaks. No gas should leak if the gun is stored for a while. I find that the last 2 shots, before the canister is out of gas, drop in elevation, signaling for fresh CO2. Rapid firing does create a cold situation which can effect accuracy. Excellent pistols. RC
Is there a .177 equivalent to the 2240 and would the CO2 performance be the same?

2300KT or 2300S and T models.
.22 caliber is slightly more efficient (gas expansion) than .177, it may even result in a few more shots but, this more obvious in HPA or PCP guns than co2, especially longer barrel .22 calibers.
Thanks BDS.
Those are all great looking shooters, but way out of my price range.
A .177 caliber barrel and bolt will get you a .177 caliber "2240" (2300) The barrel O.D. of 7/16" are the same on both calibers so, your breech and all else will work just fine. Just go to the Crosman EVP gun diagrams and get the 2300T barrel, bolt and o-ring part numbers and, if you really want to play with power and shot count, go to the 2300S diagram and get the power adjuster (assembly) part number, it's only $14! :D
My guess is $35-ish for bolt, o-ring, power adjuster and 10" barrel from Crosman. That's a cheap .177 pistol and you can always go back to .22 anytime on your 2240 :-*
PS the 2300T barrel is std Crosman, the 2300S barrel is a Lothar Walther Match Barrel $$$, be careful which one you choo$e :D
Is there an advantage to a .177 over a .22?
Depends on the use/purpose of the gun, .22 caliber is great for pest control and really whompin the sh%! out of tin cans etc
Most target shooters (paper targets and small silhouette type targets) prefer the .177 for it's speed and accuracy at close ranges like 10-20 yards. Also, at close range, a .22 can really beat up small steel targets over time.
PS before the .22 shooters get after me :D, the .22 is as accurate as any .177 if all else is equal like barrel quality, shooter ability etc. :-*

Wider range of pellet selection and .177's are usually cheaper.
Cheers,
.177 said to shoot a bit flatter, so choice of paper punchers. .20 and .22 are better choice for field target distances because of added weight, but then many folks still use .177 cal for that as well.
I personally like .22's because they are easier to handle with my crippled up aging fingers! Well, that and I like the thump of a .22 vs the .177
