I've popped two primers here recently. I   never had an issue with it.  Thousands of rounds.  Primer popped in two different rifles. I've searched and the consensus is it's great and the brass is very good stuff .  I locked up my ar and had to hammer it open .It blew out the side of the case. Blew my mag up also . The rifle lost the extractor. Warpped  it badly.  The rest of the rifle is fine.   I guess I'm retiring the ammo .

i had similar trouble with it about 10-12 yrs ago when it got imported. i dont recall the year of ammo but i think it was the stuff the brits dumped when they were trying to fix that bullpup rifle they had.

i didnt have any popped primers but one round KB'ed and dumped the mag and destroyed a bolt. the case head was all blown out and stuck in the chamber.

i figured it was a low powder charge and had a flash over. i sold the rest to a friend that knew and didnt care.

i had shot up about 2000 uneventful rounds of it before i had that happen.

I've shot thousands of rounds of it with no issues. I have an old colt that loves the stuff. God I miss the days when century was selling that stuff for dirt cheap in cans.

no problems yet

I just finished the last mine, a few days ago. Mine was '93. I never had a problem, except it wouldn't cycle rifle-length-gas guns.

I've shot cases of it.  Never a problem.

I have shot six or seven of the 720rd cans with stripper clips and bandoleers without trouble. Just checked I have two left one '91' and one '92'

I have 1 1/2 cans of 92 and 1 can of 93 . Nervous to shoot it now.  But I have shot several cans of 92 and 93 before this happened. Damn the luck .

I've shot a metric ton of it and never had an issue in any AR's or 5.56 AK's......

I did notice that some of it, as well as certain lots of LC M193 showed some signs of high pressure in an HK53 I used to shoot (brass expanding fairly deeply into chamber fluting).
