What's The Largest, Most Powerful Gun You've Ever Fired - Smallarm-wise?

Have shot Barretts in 50 bmg and 338 lapua mag. Have shot #1s in 375 H&H, 45-70 and 500 Nitro. Contenders from ,223 to 375 H&H, 69 cal musket with a 730 gr mini ball. The worst was the #1 in 45-70. Why I have no idea but it was just unpleasant to shoot.
Pistols, I have shot most. .22 to 50 S&W including 45-70 in a Contender (14" barrel) and in a BFR. Worst was a .454 in a Freedom Arms.
I have said it before, but to shoot a 45-70 in a pistol , shoot it one handed. If you try to hold a death grip with both hands it will try its best to twist your wrists 180 degrees and come out of your hands. Single handed it will roll the wrist, elbow, shoulder and waist but comes right back to home. Larry

My brother has a Freedom Arms .454 Casul he does his own reloads don't know what the loads are. He has to shoot it one handed with a slightly loose grip so won't tear up has hand. Forgot one time when it was cold out so gripped it tighter split his hand between thumb and first finger off to emergency for stitches.
