Re: Loads for 6-284 with 90-107 gr. bullets
R-22 or IMR-4831 get my vote with R-22 giving about 80 more FPS in my Rifle. I would start around 51 grains and work your way up 1/2 a grain at a time. If you go with R-22 get it in the 5lbs keg you wont be sorry that powder changes from lot to lot.
Fast, Flat, and Accurate
