No I haven't tried any other powders. Stuff is so hard to get right now. I have two pounds of 4831SC. And I know a lot of people have good results with this caliber with it.
Gave it a good cleaning and loaded 3 rounds each at 2.94, 2.95, 2.96". All at 50 grains. My book list 50.3 as the max and with my COL so short compared to everyone else I prob shouldn't go more. Can't wait to get this thing dialed in and see what it'll do. Gotta say with this muzzle brake
it kicks like my 22 mag. It's crazy. I bet you don't even need a brake on this caliber but it should let me spot for myself.
