Tested varget up to 20.5-21.0 grains. Was cycling my Sig 516 well, no problems. That was last summer. NOW, no cycling, boolits stuck in chamber, aaaarrrggghhhhh. Loading singles at home, I can chamber and eject most of them easily. Some still stick, though. Especially coming out of pmags. Ramps look ok. All measurements within spec. Cartridge overall length, COL, boolit diameter, neck, shoulder and base. Boolit from NOE 225-70-RN. Water quenched, linotype. Frustrated, do I just ditch 1000+ reloads cause the powder isn't 23.5 (Lyman rec. starting load)? And why did it run perfectly last year and horrific this year? TIA.
