Hard on the shoulder cartilage, too. Mine's shot/gone/kaput. Used to be a time I'd shoot anything- love the 'punch!".

Almost at the top was 2,050fps with 500gr. Hornady's from a 5 1/2 pound #3 in .45/70. Shot 20 rounds of those offhand with it, one after the other as fast as I could load and shoot. Stupid! The .505 Barnes Supreme with 600gr. Barnes at 2,600fps was the top of my single punishment days. That and 15,000 rounds of .458 finished what I'd started - I thought it was fun.

I'm smarter these days, although permanently injured.

I suggest finding a rifle/ctg. you can shoot comfortably that will do the job and stay away from the ones that can permanently unjure you, or your pull your retinas out.

A descent weight .450/400 is probably perfect.
