AB; I have done something similar. I have a press and scare at the farm and when timing permits I show up with a bunch of sized brass.

My chronograph died a while back, new one was just ordered.

I have settled on Varget, H4350 and H4831sc as my primary powders. IMR4451 gave a go as my first foray into the new generation of powders.

Bullet wise I lean heavily toward Nolsers or Barnes
