Good to know, I've been setting my Hammers back at 0.10 and after several primers and powders I still don't have anything to write home about so I'm going to do the Berger Test and see what happens.Berger Hybrid and Hammers are the easiest to load. Give at least .020 + and they don't care. I've heard of 0.500 jump on Hammer Hunters shooting well. But not personal experience.
I'm sure ButterBean will jump in on this.
