Well I shot that old Remington Model 81 today and my shoulder is officially p.o.'d at me. Makes an old Mossin Nagant seem like a .22. The thing bit my thumb while loading it, then it proceeded to pound my shoulder into mince meat after only one 5 shot group. Aluminium butt plate didn't help and I sure could have used a shoulder pad. Yah, I'm'a wuss. Said 'thank you very much for the experience' and laid it back down in order to spend some quality time with my other guns.
