JPNDAVE: am I reading this correctly that for Hornady brass, max H1000 charge for 147 ELD-M is 63.1 grains? (!!)
What I have experienced with my barrel (and others seem to corroborate) is that 57.5 gr H1000 is netting me 3018 FPS from a 25” barrel, which is much lower than the 61.9 shown above. I know I don’t have a fast barrel, as it shoots factory 147 around 2900.
What am I missing here?
