Hey guys,
Check my head for me here, I loaded some 75gr VMax with 29.5gr of Power Pro Varmint, and it would only extract them part way, or when they did eject it wouldn't pick up the next round. Brass is converted IMI 7.62x39, crono reading was 3080fps for that load. Factory Hornady Black 105 HPBT cycled fine and cronoed 2658fps. This is out of the 20" Monster barrel, A2 recoil buffer and spring, M16 BCG, accuracy was good with both loads, I took the 105gr all the way out to 600 yds on steel no problem, took the 75gr out to 300 yds before I got fed up with it jamming and not cycling.
So, ideas? Up the powder charge? Punt?
