Went to my Fish and Game Club today. The Boy Scout Troop we sponsor and make a building available to had a big cookout for us. I took my Blackhawk 357 with me just for some range fun. 5 of the rounds from the box of ammo i took with me had ALOT more recoil, and more muzzle flash. As i was removing them i noticed the split cases. Heres a pic of 2 of them. Some of my friends that were there asked me if they were hot home loads.. but no, they were right out of the factory box. Anybody know what could have caused the brass to split on some of them ?
