Hey Guys - I figured I'd run this by you all since there is a vast wealth of experience on this forum.
The standard ammo we use here for testing guns is currently, and has been for years, Federal American
Eagle 230 grain copper jacketed ball ammo. I would estimate that I have fired/test fired close to 300 Thompsons.
Its been over a year since the last one but I have in the shop now a gun for which the Federal ammo
does not provide enough power. The symptom is short recoil. Either the bolt does not recoil back far
enough to be held by the sear on semi, or the bolt does not recoil far enough to pick up the next round in the mag.
When this happens I switch to Israeli Military Industries 230 grain ball ammo and in all circumstances
so far a gun that will not work with Federal will work with IMI. I consider IMI to be the hottest .45 ACP load
available. Its a very fine line because the IMI ammo is not considered to be a "magnum" loading.
I am looking for similar experiences you may have had. I am not intending this to be a poll of what is the
most popular ammo. I am looking for examples where a gun was under powered with ammo "A" but worked
fine with ammo "B".
Many Thanks in advance
