I just purchased a Crosman 2240 pistol.  The included instructions say not to leave a "Powerlet" in the gun when not in use.  Has anyone had experience with this?  What damage may occur?  It seems a waste to take only 10-15 shots and then remove the Powerlet.  If the Powerlet is left in the gun, about how long will I expect it to maintain pressure?

I leave "powerlets" in guns all the time. If properly sealed, they should hold pressure indefinitely. Probably two concerns might be that you forget that the gun is "loaded", and if left in for really long periods of time, they might get stuck. A very light wipe with oil on the outside of the cart, and a drop of oil on the tip(especially this) heol keap things sealed and prevent sticking.

I think it meant do not leave a  powerlet in the gun for an extended period of time, in other words in storage. I have left powerlets in mine over night and even for several days with no problems. I always put a drop of oil on the tip of the powerlet to prevent it sticking to the seal. The only problem I know of is if a powerlet is left in the gun for an extended period is it could either stick to the seal or actually make the seal take a set and leak when the net powerlet is put in. I have not modded mine (other than smoothing out that horrible trigger) because I like the power and number of shots I get from the gun. This gun shoots closer to the advertised velocity of 460 FPS (14.3 grn pellet at 455 FPS, chronied) and is as accurate or more accurate than my modded 150's. These are accurate and powerful guns bone stock and a blast to shoot, enjoy.

2240 will hold CO2 pretty much indefinitely, if you treat it right.  The biggest  failure mode is over tightening.  This squishes the cart seal beyond what it was designed to do, and will soon lead to seal failure.  Best practice is tighten the cap only hand tight, then fire to achieve piercing and full pressure.  Once you have full pressure in the gun, back off on the end cap a little bit until you hear a slight leak, then tighten back down just a bit to make things right. 

CO2 seals can last a really long time if they are not overly stressed by tightening things too tight.

Thanks to all for the prompt replies, this was my first post.

My Gun Club has just built a really nice indoor pellet gun range....I thought I should get on board!

I think they mention not to leave the powerlet inside the tube because it may get stuck.

I think it would be bad for the seals if left for prolonged periods of time sitting without CO2 pressure IMHO.

Might be for safety too just in case a kid finds it.
