[QUOTE="J E Custom, post: 1768018, member: 2736"] Actually, It is very simple. Decide if you are going to load to magazine length or single load the rifle. Then work up the load with the COAL to Mag length - .020. After you find the load then you can tweak the length shorter or longer to find out what shoots the best. All of my hunting rifles shoot Mag length ammo and 4 of them will shoot under 1/10th MOA groups because the loads were worked up at those lengths. One of them is a 30/378 that has .371 freebore and the others have close to .200 freebore. Bullet jump is .105 thousandths in the 30/378 and the tightest dimension is .035 in the 7/08 to the lands. I don't want to give up velocity and add pressure by seating against the lands, So I load Mag length on all of my hunting rifles. and they will all out shoot me. The least accurate hunting rifle I have shoots a consistent average 1/4 MOA and on my bad days it will stay around the 3's (.300 thousandths 5 shot groups) So my recommendation is to work up your load the way you want to shoot the rifle and in the same condition. (Clean, slightly fouled or fouled) to get the best from it. Just My opinion J E CUSTOM [/QUOTE]
