[QUOTE="65WSM, post: 1731935, member: 9551"] I too have found about 1.5 Thousandths under bullet size provides the neck tension that is the best compromise in variety of 6.5, .270 and 7mm applications. I have found that polishing the inside of case necks with steel wool wrapped around a cleaning brush and motorized in a drill helpful as well. The K&M mandrels are helpful in achieving the 1.5 thousandths inside diameter after sizing with bushing dies. I also coat all bullets with HBN. No naked bullets. The first shot from a clean barrel will shoot into the group of following shots. I hunt with a clean barrel. Barrels last longer. [/QUOTE]
