It's been a long time favorite in the 338-06. Old writings just about stick to it.
With newer powders, like BG, RL-17, etc. 4320 may not be the top performer. But, it's still a good one in that round.
I started out with 4320 in my recent .338-06 project, but find myself using H-380, RL-15 and others, Varget with lighter bullets.
