Carl Quick's LiteWieght 2240

So for about the last 24 months, I've had her on a serious diet. Now I am happy to report that she lost nearly 13 ounces and is feeling so much better. And let me say one thing, when I pick her up with one hand now she is light as a feather. Well, almost a feather.

Things I have done so far:

OEM main tube was lightened by me.
Barrel is OEM and trimmed down by me.
Main tube plug is made of Delrin by me.
Gas cap is aluminum, comes from HPA and bored out by me.
Hammer is made from Delrin by me with a modified 1701P striker.
Valve is an aluminum Disco rear end with a brass Pro-Top by Anthony.
Trigger grip frame is aluminum by Bluefork Design and then hogged out by Gregg.
Front barrel band is aluminum, made by Anthony, drilled by Rich and milled by me.

Crossman Powermaster 760 repair

Have an older Crossman Powermaster 760. Has the wood stock and handguards, blued steel barrel and leaf sight. Not certain of the age, but it has a square button that you push in to load and unload bb's. I'd guess either late 60's or early 70's.

Issue is yesterday a 177 pellet was put into the breach while lead BB's were inside the rifle. First pellet shot worked, but on the second shot the pellet jammed in the barrel. Managed to use a coat hanger to clear the bore.

Now when you pump the rifle it doesn't hold air. Before there was tension when pumping the rifle, now there is none. Tried to oil the seals, but so far it makes no difference.

Any suggestions for repair?

Once every 40 years........

Congratulations Dave, you've made it 40 years on those old seals, and it's finally time to replace them.
That old girl is loosely referred to as a Phase 0 gun, made between 1966 and before July 1975. It'll need a 760SC Seal Kit that you might still be able to get from Crosman. The kit contains part numbers:
111A026, 130-034, 130-035, 140-058, 760-037, 760-042, 130-057, and 1400A029.
Give them a call and see if they can fix you up with the parts. Good luck!
