450 Bushmaster with Unique, HS6 or 2400 powder or ANY proven medium loads

[bluejay75]

Greetings Gents,

I haven’t started loading for the 450 Bushmaster yet but was wondering what you guys have as proven loads. I am interested in medium loads. Maybe 1500-1700 FPS with 300 grains or less boolits.

I am shooting them from 2x Savage Bolt actions so cycling an AR is not a factor.

1.5 MOA is the goal.

If you don’t mind sharing your proven loads. Share the following:

Boolit or Bullet
Firearm
Velocity estimated
Powder and charge
COAL
Group size

Thanks in advance.

5744 & #9 have been best for me. RARR 16” 50&100Y

4227 load took a bit but hit 1900 MOA ACCURACY with a 457191 Lyman bullet.

I have loaded 230gr ball with lil gun. Really eased the recoil. I thing I used the starting load listed.
