First post on the forum, this place has been a huge help with my first 6x45. I figured I'd share a few loads to add to the database in return for the info I gathered from here.
All of the loads below were fired from a 24" Blackhole Weaponry 1/9 twist barrel. Velocities are recorded with the chrono at 15ft. These loads were well within safe pressures in my gun, yours may be different.

**Disclaimer on the Hornady 87gr BTHP/IMR8208 load. I took it out to 400 this weekend to confirm the drop and I think my chrono is reading low. By all means it should have taken 7MOA to hit dead on at 400, my correction was 6.4MOA. That puts the speed closer to 2925, 104fps faster than recorded. The wind drift was matching spot on as calculated by both JBM and Shooter using real-time environmental data as well.**
