300 Win Mag powder recommendation

[EOD3]

I need to work up another "accuracy" load for my AT&T rifle. My current load uses RL22 but given the current availability situation, I need an alternate powder (or I'll have to mix 50/50 with match heads pretty soon).

Which powder(s) give you the most uniform pressures/velocity?

Tried to post this in the precision rifle club forum but...

Going to try out the IMR 4831 brand this time around i have them loaded but havent made it to the range.This is a temp deal for me since i finally got the rl22 load worked up.

But who knows

RL22

I used to use RL-22 but never got it to work with any of my bullets (155 Scenar, 168 SMK, 190 SMK). Then I switched to H4350 and life has been good. Consistend velocity and excellent accuracy. I use 69.5g of H4350 to push the 155 Scenar at 3050 FPS (3100 FPS is usually the match limit).
