I use Winchester brass, CCI250 Large Rifle Mag primers, 73 grains of H4831, and the 208gr Amax. My OAL with using the Hornady comp tool is 3.990 which is 10 tho out of the lands, ON MY RIFLE AS YOURS WILL BE DIFFERENT BUT I WOULD START WITH 200GR LOAD DATA FOR YOUR POWDER AND WORK UP TO MAX, AGAIN THIS IS WHAT MY RIFLE LIKES. Use this website, Cartridge Loads - Hodgdon Reloading Data Center - data.hodgdon.com , its a good site from Hodgdon that gives MIN and MAX loads. At least gives you a starting point. Other then that have fun and shoot straight. -Jake-

I use this bullet in my 300 Rummy pushed to 3164 fps. I shot a deer with this past season at 475 yds (or so) and it delivered violence very efficently. gun)
Slowing it down to 2900 to 3000 fps is a not a bad idea.
