I’m writing about two trusted sources with their top loads 5 grains apart. Same velocity. Same powder. Same bullet.
Different powder lots? Different brass than tested? A lot of Lapua 30-06 brass I have locked the bolt with a 3 gr (5%) charge reduction of a trouble free warm not max load wth PPU brass. All other components the exact same.
