I have a Mossberg MVP V&P in 5.56 (24" barrel 1:9 twist). I am shooting Winchester 5.56 mm 55 gr FMJ ammo. This is out of a 1000 round case I bought several years ago.
I am getting quite a few duds (1 out of 20 is typical with 5 out of 20 in one box). The primer dents on both fired and dud rounds look about the same to me. And they look a bit on the light side. I have shot .223 (mainly American Eagle and PMC). I don't think I had anywhere near as many duds with the .223, if any.
I am trying to figure out if I have an ammo problem or a gun problem. I have read a lot of articles on 5.56 vs .223, including the June 2012 Lucky Gunner Labs article with his test data. But I am not sure I learned much to help me figure this one out.
I can find exactly nothing about the primers used in the Winchester ammo. So I don't know if I have hard primers, or what.
I gave 5 of the duds to a friend with the same rifle, to shoot and see if they fire in his gun or not, when he gets around to it. In the mean time, if anyone has any ideas, thanks for the feedback.
