I watched a guy blow up a SIG in .357 SIG. He had called me over to look at some pierced primers and ripped rims he was getting. He couldn't understand why they were blowing since he had "followed the book and was only at maximum and everyone knew that was lawyer low". After talking to him I picked up my stuff and moved well down the line. Sure enough, he blew the gun up the next time we went hot. Seems he was using .357 rather than .355 (9mm) bullets. I also watched a guy shooting identical Ruger 77s in stainless except one was .308 the other 30-06. He didn't blow it, but it took him a while to figure out why his ejected brass from what he thought was the 06 was straight walled. I moved away from him too.
