...after 3000 or so rounds and I think it was my fault.
Last COF of the day shooting standards. I didn't fully seat a P-mag, it dropped out into the dirt while prone and instead of shaking the crud out of it I snapped it back into the rifle. I had two failure to go back into battery in a row.. Tap rack bang 2x, finished the COF.
Back on the bench ran a q-tip around the feed ramps and cleared out a good clump of dirt/grit. No damage to the bolt head or lug recesses so it was a dirt clod not a rock.
Ran a couple magazines after and no issues. Dumped a teaspoon full of dirt out of a P-mag when I got home. Hmmm.
We'll see how she does the next 3000.
