A little warning. Yesterday while shooting one of my AR's, I experienced a slam-fire. It was while I was single loading rounds during 200yd standing. After inserting a round in the chamber, as usual I tripped the bolt release and BOOM!. At first I wasn't sure whether it was me until I saw the smoke coming from the receiver. Upon ejecting the case, I noticed that the primer was pierced by the firing pin. I have no idea what caused it and can only assume that it was down to a high primer. The rifle was pointed down range at the time, and the bullet struck the ground about 20ft forward of the firing line. No harm was done, but it does shake you a bit. Please always be sure that your firearm is pointed in a safe direction when loading. It can happen any time Mark |
... Did you get my email?

Got my butt kicked once on a firing point by Raf Regt Flt Sgt. I'd had a stoppage on fall asleep snaps and cleared it, had alive round next to me, which I tossed into to the ejection port as soon as weapon locked open after round 9. Bolt released forward got the shot off no probs. His gripe was that it was a magazine fed weapon and I wasn't allowed to by pass the mag, in true regiment fashion he couldn't give me a reason, "it's what the book says". Looked it up for my self, if the bolt isn't slowed down by stripping a round from the mag as it goes forward, the floating firing pin (same as AR family) can gain enough inertia to detonate a defective primer. Thin or proud would do it. Like SF says, if the muzzle is pointing down range while doing drills, less risk of any harm done. |
What was the round Mark, Milsurp, homeload or Factory ????

evil people could miss use them.
What do you mean no chance nowadays?!?!?! I have a Norinco copy of the Winchester 1897 pump action shotgun (and 1887 Lever action) sat at home in the shop, which you can slam fire! |
Slam fires are not fun. We shot a comp on sunday and one of the competitors suffered 3 slam fires in succession. There was no cause apparent at the time, and the bolt face looked fine with the firing pin as it should be. On dismantling the bolt it was found that the firing pin had become dislodged and shifted meaning that as the bolt was cocked it sat proud of the bolt face by 3-4mm!! (it was a BA rifle) The competitor in question was lucky that the bolt lugs had partially engaged before the slam fire occured otherwise he might have been pulling a bolt out of his right shoulder I suppose the lesson from this one is to check your bolts regularly. I had some soft strikes on a brand new upper (not a SF upper I should point out) and on dismantling the bolt and carrier found a rather large chunk of metal in the bolt which was causing the firing pin to stick back.....I suppose it could just as easily have caused it to stick forward leading to slam fires.  |
Aye...it was the unintentional ones that I was refering to mainly  |
I didn't realize that the Norinco 1897 could slam fire. I always assumed that function would have been removed. |
Wrong ..... Ithaca mod 37 is still being made. I have one.............MUHHHAAA
