This may be an old topic, but I'm a new member so let me hit the proverbial dead horse one more time if it is. I've recently bought a Springfield M1A "Scout" rifle. It was used, but in excellent shape. The paperwork that accompanied the rifle warned about slamfires if shooting anything but military surplus ammo. then I started to read magazine and internet articles about slamfires. Research has revealed that this phenomenon is most likely caused by non-military primers, or improperly seated primers. I purchased the CCI military primers to use in my reloads, but was wondering how safe it is to shoot commercial ammo in this rifle. Are all these slamfire warnings just CYA by the manufacturer and their lawyers? I know that slamfires occur, but are they common enough to be concerned about? Of the several military clone or military surplus weapons I, or a family member, have owned or shot, I've never experienced a slamfire. I'm not that great of a shot anyway, but when I'm nervous about the gun blowing up and taking a hand, eye, or my life, I really don't shoot well. All of you who regularly shoot these old war-weapons or their clones, have you ever had a slamfire?
