Apologies for the crickets, finally off the mountain long enough to reconnect with the world.I have a few charge weights shooting 1/2 moa with the 225s...but the node is only .5gr wide it seems. Still working on it. Those are seated .020 off in ADG brass with CCI 250s....I could not get to a high node with H1000 and 225s...I'm working around 74.3 grains right now, luckily I'm at 7k msl...so that'll be the only thing that gets me close to the 'magical' 2800 FPS for this bullet.
Mind sharing your load data?
I'm shooting a 22" Pac-nor 1:10 with an Omega can. I've found my node right around 2775 fps. My node has a span of around 1 grain give or take. Next node up is 2840, but I get signs of pressure there. Shooting with a shorter barrel I realize I'm going to take a velocity hit, but I'm OK with that. 26" barrel is just too long for what I do.
300 Win Mag
H1000 73.5 gr
S&B once fired brass
I get velocity SD of right about 15 fps. I believe I could get lower with better brass and not using a magnum primer, but it's acceptable for what I do. I'm not a bench rest shooter by any means.
Group in the attached image was on 9/30/2019, 100 yards, 5600 ft elevation, 55 F, 24.05 baro, 31.5% humidity.
I'm curious what rifle/barrel are you shooting?
