Only slam fire I have ever experienced was a very long time ago with an M1 Garand. I was educated that day by an older gentleman who had been loading for and shooting M1 Garand's in competition for years. "NEVER USE FEDERAL PRIMERS IN FREE FLOATING FIRING PIN RIFLES." I was using F210M. I was at the bench and it doubled once with the first clip and I thought it was just my trigger pull through and during recoil caused me to pull the trigger again. Next clip it tripled and the old gentleman came running down the firing line yelling cease fire. Then he educated me. Federal are the only primers I have personally seen used in any slam fire situation. I once witnessed a slam fire of an AR and the fellow was using the standard Federal SR primer. They are thin cupped and very sensitive. When I was a kid I did witness a 22 lr semi auto go full auto. My friends dad tried to fix, by making a new firing pin, a rifle that somehow the original one and gotten lost. He loaded up the rifle that had a through the butt stock loading tube magazine. Pulled back the action and let it go home and burrrrrrrrrrrrrr it emptied the rifle. Lucky we were outside and he had the rifle pointed in a safe direction. He discovered that he had the firing pin too long and it acted like a machinegun that operates from an open bolt that has a solid bolt firing pin set up.
I have shot a lot of CCI 200 primers in M1 Garand's and M1A1 rifles with no problems.
A old fellow I know had this happen with a Rem. 760 30-06. He was in his 60's, very over weight and had chain smoked one Camel no filter cigarette after the other most of his life. He begged some other fellows in the neighborhood to allow him to go to VA from TN deer hunting with them were they had a hunting lease and ran dogs. They let him go. He had a brand new Chevy truck. Since he could not walk for more than a few yards without being out of breath they let him go down to a dirt road cross road on the property where there was a field that deer sometimes crossed. He went down to the cross road got out his truck got his rifle out of the case and laid it down in the seat. He loaded up his magazine and with the rifle barrel still resting on the seat placed the magazine in the rifle and hit the bolt release sending the bolt home. Now this fellow had big fat fingers, He no doubt had the safety off and had his finger inside the trigger guard when he let the bolt go home. That fat finger pulled the trigger when the bolt went home and the rifle continued to fire with subsequent recoil activated trigger pulls until it was empty. It blew the passenger side of the seat to shreds and there were 5 bullet holes across the bottom of the door. To the day that fellow died, which was not too many years later, about every time he came into the little country store where the old fellows gathered someone would ask him if he had that truck skinned and in the freezer yet.
