As I sit waiting for my brass to arrive, I am wondering about the most suitable powder. Two of my manuals list h414 as top powder, one RL 15 with 2 not even mentioning RL15. Manuals are a little older. I like RL 15, have not used h414 but would prefer not to use a sperical powder. I would prefer a hogdon extreme powder if one is suitable.
So what do you more experienced folks use? for 286 nosler, 270 speer and maybe 250 accubond. I'm excited to get this thing in to action soon.
