what powder form75gr a-max in 223?

Re: what powder form75gr a-max in 223?

Another vote for Varget but RL-15 is right there also. If your loading on a progressive take a look at Ramshot TAC, flows like water and very, very close in burn rate to Varget and '15.

I am having great but similar results with Benchmark and varget. Cant hardly tell a difference. My Armalite 24" target ar is shooting these 75gr a-Max in the .3's Very impressed. I just didnt know what powder had the best burn rate for the heavier 75gr bullets? Lee
