Hello all, been lurking around here for a little bit trying to sniff out an answer to my problem without asking for it but I'm not really sure on what I should be asking... Problem is, I'm not the reloader, my father is. I know enough about it to get me by...I think.. Anyway, My dads been reloading all types of calibers for 40 years or so and I have the utmost confidence in him, but when it comes to this 450B he's been getting his A handed to him... We've been all over the spectrum with load charges and bullet weight combos. The best we've been able to get is just OK I'd say for a cheap Ruger American (22" barrel), about 2" groups. We're using a Hornady Die set, horandy brass and starline brass, 225,250,300 and 300mag bullets all from hornady. The 300 have shot the worst by far. LG has been the propellant for most of the testing, with some H110 being used in the early stages.
We're both good shooters, and he's a great reloader but I'm at a loss for accuracy. As much as I didn't want to, I went a bought some Factory Hornady Black to make sure it wasn't something with the gun, and it shot much better than our reloads. It grouped like I how would expect our reloads to. I've put a Boyds stock on it, with the blocks bedded in. Barrel is free floating of course. Glass is A Leupold VX freedom 3x9. We're probably approaching the 400 round count or so in this gun and are struggling to get a consistent load to shoot from it. Thoughts?
Thanks boys
