Anybody dumping 58.3 grains of H1000? Seems like a lot, but when I was making ladder loads I had 4 really consistent rounds. 2 were 3144, another at 3143 and the 3rd was 3146 as measured by my Magneto Speed. Seems really fast and they are accurate, but I don’t want premature barrel burnout. This is using Federal match primers and Berger 140 hybrids.
