the hand guard is a beast to get off this rifle for whatever reason... but the mag well is stamped .308 WIN.
Though there is without a doubt some problem, I have now found(after being "detailed" at the shop) that SEVERAL different brands of factory ammo are working while others are not. I literally went through EVERY brand and weight my gun shop hand including their person stock, finding what worked and didn't. I may be wrong here but I have always been under the impression that Barnes ammo was of "better" quality, found out the Rachel doesn't like feeding them either, but anyways I found and acceptable round to use for deer and coyotes (ordered 5 boxes) while my competition rounds still function fine. Problem solved...Er... managed.
Thank you everyone for the knowledge, pointers, and the time to type them for me.
