Greetings all. I have a question regarding ammo, specifically Q3131A. Here's the story that got me here.... Took out my Bushie M4gery to the range. Second trip, already broken in. I took with me about 120 rounds of surplus FN ammo, 55 grain, and 100 rounds of Q3131A. FN was flawless, first 40 rounds of Q3131A, flawless. Next box, load, get to the third round, and something feels wrong. Look inside the ejection port, and I have the spent casing from #3 stuck in the chamber with round #4.
After I removed them, ran 3 more shots, jammed again. Pulled ammo out of clip, ran some more FN, nothing wrong. Ran 30 rounds of Wolf, no problem. A friend at the range took 30 rounds of the Q3131A I had and ran it through his RRA M4gery, no problems. Ran it one more time in the Bushy, jam. What am I missing here(besides the ability to make a long story short)???
Appreciate any help you guys could give.
P.S. This is one of the greatest sights on the web.
