We'd like to shoot this beast tonight or tomarrow, and I'm hoping you'll all pile on here and advise us what to do for starting loads. My brother just finished his 500 Jeffery throated for the 750 A-Max and has some H50BMG, H870 and a few others, so where do we start.

I figured anyone with a 50 Peacekeeper, 510 JAB, the Jeffery, Quickload might help us get an idea for a starting load. The bullet is seated roughly 8/10ths of the way into the neck, bearing surface wise.

Barrel length is 36", somewhere around 39" w/ brake, and is on a Ruger #1. I'll post a pic when I get one today or tomarrow.

THANKS FOR ANY HELP!!!
