Good to know it's not just me then.
What rifle/twist were you shooting?
Built my own with the same barrel you're using, 16" BHW 1:8 3 groove poly... Maybe it was just my shooting! I only had a 4-12x scope on the rifle for load development, but it should be plenty for 100yds. By the way those velocities are from last summer in NC so the temp was at least 80 deg.
Forgot to mention I was able to get .76" group with Hornady factory 75gr HPBT ammo. Was a little frustrating not being able to consistently beat it. I didn't get to shoot it through the chrony the day I shot the ammo. I'll have to try this whole test again hovering around 24gr Varget when I get a chance. If I can find out the velocity of the factory ammo, I assume I'll be able to get close to the same performance out of my handloads. It'll be a while before I get to the range, but I'll let you know what I find out when I do.
