Thompson 45acp

Broomie2
I need help choosing a powder for the Thompson SMG (New Karh type). Im going to be shooting a 230 grain jacketed bullet out of a 16 1/2" barrel. I use Bullseye now for my Colt pistol 1911A1 which is a fast burning powder. My guess is my performance will increase using a slower burning pistol powder in the longer barrel. Any sugestions as to a slower burning powder?

Thanks Rich

    I just purchased a Thompson (Auto Ordiance) in 45acp 16 1/2" barrel. My question is, can any 45acp ammo be used in it? I also handload, and was wondering if the Speer manual 13 info. on the 45acp is acceptable info. for reloading it? Can I used semi-wads or round nose work best? Anyone have a pet round for this gun? I would perfer to stay with lead bullets as very few loads seem to top the 1000ft a sec. Sorry for all the questions.

    You might try some IMR-4891...but start slowly...pressures will increase dramatically.
