Walking AR trigger pins
I've been having a problem with my trigger and hammer pins walking on both of my AR's recently. I've never had the problem before I started firing 77 gr. SMK's loaded a nun's cunt hair below the maximum rec'd charge. In fact, I went through roughly 600 rounds of HOT 60 gr Noslers with no problems. Didn't get more than 6 rounds out with the 77 gr loads before the pins walked out.
1) Anyone ever had this problem before?
2) How did you go about sorting it out? I'm thinking of investing in the JP anti-walk pins, though don't know if the walking pins is indicative of a bigger problem.
