Me and a friend was shooting his new M&P15 its the Optic ready model. Shot about 60 rounds of steel case through it without a issue. Well he had 2 boxes of this PMC Bronze that he paid $14.99 a box for. I loaded it up and fired the first round and when it tried to chamber the next round it bent the bullet and not putting it in the chamber. It kept doing the same thing. I sold him 100 rounds of Wolf WPA 55gr FMJ so we loaded a mag with it and it fired flawlessly. These PMC bullets dont look right to me. The brass looks like 556 brass you know the end where the bullet is looks like its been heated and color changed like all 556 does and the primers are sealed with red stuff. I have 300 rounds of this PMC and its all nice and shiny and no red sealer on the primer. Here are some pics what do yall think?? Has anyone ran into this problem with this ammo?
The discoloration around the neck is the result of annealing which is common to see in some ammo. The IMI .223 I saw recently is that way. The red color is just a sealer around the primer. I have shot mucho boxes of PMC .223 thru the same gun, an OR S&W, and have never had any problem with any of it. Can't imagine why it is treating the brass ammo that way and not the steel.

Yea I dunno either. I tried taking the magazine out and pushing down on the ammo making sure it was in there correctly but it just wouldn't shoot it for some reason. I thought maybe something was wrong with the ammo. Since his PMC looked nothing like mine did.
Obviously a feeding problem. Could be a bit underloaded and maybe
just not producing enough pressure to fully retract the bolt for reliable
cycling. I chronographed some PMC Bronze in my 16" Colt and it ran
about 200 fps slower than US military issue from the 70s.
