I have shot .45-70 revolvers, and .454 Cassull. I've shot a few rifle rounds in Thompson pistols (8mm Mauser in a handgun was by far the worst). It was fun for a few rounds, but the older I get the less I feel I have to prove. When I was in my 20s and I shot a ludicrous handgun or rifle, a sore wrist or a bruised shoulder was an inconvenience of a couple of days and a badge of honor. Nowadays I can stove myself up just sleeping funny or twisting funny when trying to get the toilet paper. Except for an urge to own a revolver in .30 Carbine, I no longer feel the draw to weirdo handguns in the intermediate-caliber-to-rifle power range - unless you are talking the various Tokarev-caliber guns I (totally do not) own (if the government is monitoring.) For handguns, I don't shoot anything more powerful than a Tokarev on the speed end of the power scale, or a .45 Colt on the mass side of the scale. My rifle caliber of choice for the last few years has been vacillating between .303 Brit and 7mm Mauser. I do have a chance to shoot a match .50 Barret this Fall, and the owner assures me that between the break and the way the stock is designed it is not as bad on the shoulder as shooting a 12-ga. Who knows. It might never happen. I was supposed to shoot a Chauchat this Spring and Covid boogered that up.
