Re: 6mm Rem AI
Joel, I have had two based on min spec reamer and zero freebore for shooting lighter bullets.
I shot a fireforming load of 51.5g of Win 760 in winchester cases with fed 210's, bullet seated to touch the lands, velocity of 4050 fps in a 26" SS barrel, grouping in the high 3's. In the formed load, I shot 52.5g of 760 with a 70g Ballistic tip, accuracy was in the 3's at 4150 fps.
Every barrel is different along with lot # of powder so work up to my loads.
