Years ago... I'll never forget the day I saw my father shoot a 10" open-sighted 357 Herrett with a hot loaded 200gr bullet. I'm positive the load was hotter than published data. He was wearing a deerskin glove with the trigger finger cut out while shooting over his chronograph. He touched off that round and the pistol flew out of his hand and landed on the ground behind him. I laughed my butt off.
First time I touched off a 375JDJ in a Contender, it almost flew out of my hand while shooting it off sandbags one-handed with a not so firm grip. I didn't think it was going to recoil that much. Way more than factory loaded 45-70...
