Mags used were Brownells 30 round, with dark grey Magpul followers. Purchase 10 about 3 or 4 years ago. They were new in package before today.
I had 5-6 malfunctions where the round would try to chamber and stop just a smidge out of battery. On finding a dead trigger I would try to clear the malfunction and once had to mortor to extract the round. The rounds looked a bit "bent". Not sure if that is a good description or not. I'm digging through my crap to see if I can find one of the damaged rounds.
My instructor suspected the mags. I isolated one mag, and set it aside, but had one more malfuction with another mag. I used a total of 4 mags in the class.
Ammo used was Wolf GOLD, vintage 3 years ago. Never had an issue with this batch of Wolf before.
Anybody have any ideas?
