Hi;

I have a completely stock M&P-10 and have put a total of about 80 rounds through it. I tried many different types of .308 ... a couple different Hornadays, Fusion, Federal Power Shok; most of them being 168 grain since I had read that 168 grain seem to give the best groupings with the M&P10. When I picked up and shot some Federal Gold Medal 168 grain I started to get failure to feeds about every other few rounds. Went back to the other ammo no problem. I use the PMag 20s gen 3 so I doubt it is a mag issue. Even had a gun smith look my bolt assy and receiver over and it looked fine to him.

Obviously my rifle is allergic to the Gold Medal. Was curious if I'm the lone ranger or if anyone else has had this issue?
