[QUOTE="dok7mm, post: 1837364, member: 90080"] Using Nosler brass for my son's 280 a.i., I ran into the same thing. I turned 12 cases to .0135" and 12 to .013". They shot similar groups @ 400 yds, both about 3/4 moa. I prefer to keep total clearance to .004", but in this case I ended up turning them all to .013", as he is using a bushing die to size necks and liked the lowered ES. If you're using a mandrel to size necks, the .0135" turn would be my choice. I shoot a straight .280 with Norma brass that is just skimmed about 60-70%. I use a .282 mandrel to set neck and it shoots in .1s pretty consistently. [/QUOTE]
