I took a bunch of people shooting yesterday and consequently my AR saw a lot of usage. I had mags filled with a mix of American Eagle and Wolf. I'm trying to use up the wolf cause I hate it. Sure enough the case from one of the Wolf rnds glued it's self into the chamber and I had to beat it out with a cleaning rod! The gun was very hot, but the American Eagle ammo that I was using after that ran flawlessly.
I do not have this problem with Wolf ammo on any other gun and I don't have this problem with my AR with any other ammo.
I had my brother try a mag full of wolf in his Eagle Arms AR while it was hot and sure enough, he got a case glued into his chamber as well!
Fair warning, if you shoot wolf you had better keep the gun nice and cool!
