If you look at post 41, WildDeuce posted pictures of factory new W/W ammo that slamfired in his rifle.

I have never heard of an out of battery slamfire with an AR. I have one in battery slamfire, and same day, same firing point, next relay, my shooting bud also had one. Mine was with WSR, his with Federal small rifle.
You are most likely to have a slamfire when you put a round in the chamber and drop the bolt.
Enough of these have happened in the standing stage of Highpower, that the rules now forbid you to load the rifle on the stool. Some folks used to put the muzzle of their AR on their stool, load a round, drop the bolt. I heard one shooter put a bullet through everything in his stool!. Another bud of mine was shooting standing next to a Junior. He said "the Junior was loading his rifle "in a dangerous way"". I suspect Junior lifted the rifle up to his head (so he could see the chamber) , put a round in the chamber with the rifle parallel to the line, and dropped the bolt on the round. (I have seen guys doing this). In this instance the rifle slamfired and the round went throught the air between my friends left arm and his body and blasted a divot out of the ground.
The NRA rules have been changed such that if you discharge a round into the ground within 10 feet of the line (might be 10 yards), you will be sent home.
This was due to slamfires in AR's.
I have been using CCI#41's in my AR's and they shoot just fine. I have never shot a 200 at 600 yards with the .223, but I have come close. End of July I shot a 197 with a load of 80 SMK 23.5 grs N140, W/W cases CCI#41 primers. I was working on a 199 until the last two shots were 9's. It was so hot............
I don't have any chronograph data on the #41's, but I have not had to cut my loads from the old nickel WSR. However the new brass finish WSR, those primers pierce so easily with loads that never bothered the nickel plated ones, that I ain't using them anymore.
Back in the bad old days when good two stage triggers were not around, tuned single stage triggers would occansionally double. You would hear this burp in rapid fire. At the end of the string we would call down to the pits that their might be a missing shot. However, with the .223, the shots were always on paper. Unlike the days of the M1a, when a 308 doubled, the second shot was on its way to the moon.
I personnally saw shooters have doubles with Jewel triggers. Call it triples. The shooter had adjusted the Jewel to give an extra light trigger pull with minimum sear engagement. The hammer followed the bolt and I saw a string of empty cases tumbling out. I was next to the shooter when it happened. Since it also happened on his alibi string, his chances of winning were over for the day.
