. It now works fine with anything with a little impulse. I could play with the recoil spring, but then it would beat itself excessively with high speed stuff.
You're looking for 290-310 MPS ammo; if the 41 won't run on this, the gun's broke; lubricate it, or fix it!
Tom, as an aside, WTF would you run high speed ammo, in a target pistol?
It's neither accurate, nor prudent, and will darned sure beat the gun up, as you stated!
Copper, vs lead, same answer; if you are having problems with unplated bullets, that plating 'resolves', fix the gun!
I shoot a couple of Win 52's, a couple of Hi-Standards, and a Stevens 44 1/2, all of which see no more than an occasional 'dry patch', through a season; all deliver results beyond my ability.
If the plated vs unplated thing is truly a firearm, rather than shooter,issue, you need a barrel, not a change in ammo!
