[QUOTE="Bobrob, post: 968957, member: 3729"] The Garand design was designed to prevent "early ignition", or "out of battery" events. The firing pin while floating, has an "L" shaped "heel" that must pass through a notch in the receiver web, before it can move forward far enough to strike the primer. Additionally the hammer has a "spur: on the face that must align with a notch in the rear of the bolt, before it can contact the firing pin. That's how the system was designed. Now add in wear (some are 70 years old) and or "modifications" by well meaning, yet uninformed ex-owners, combined with a high primer, and you may suffer an "out of Battery" event. Over on the CMP board, some of the "greybeards" recommend loading up a primed case, and holding the oprod back out of battery and trying to fire the primer. Move the oprod closer toward full lock(battery) until you determine at what point the actual ignition will occur. If you find the primer can be fired at anything less than 99% of the bolts rotation, consider the rifle unsafe to fire. Slamfire on the other hand is more like doubling, Hammer/sear enguagement is too light or excessive wear, where the hammer falls immediately after lockup. When this happens the whole clip or the remainder may be dumped.(fired) I don't think this condition is caused by primer brand. My definition of "slamfire" usually doesn't do further damage to the rifle, although it is dangerous.( muzzle always pointed in a safe direction) Out of battery fire on the other hand is the stuff nightmares are made of.(did I mention eye protection, yes ALWAYS) Best regards and enjoy.
