[QUOTE="Bart B, post: 568863, member: 5302"] Your die's neck diameter may be too large to size the fired case neck down far enough. If you use an expander ball in the sizing die, the die's neck diameter needs to be at least 4 thousandths smaller than a loaded round's neck diameter. And if you die uses an expander ball, it may be too large. For .311 inch diameter bullets, it typically is about .310 inch. If larger, bullets may not be held tight enough. Depending on the quality of the brass and the difference between sized case diameters and chamber diameters is no more than 3 to 4 thousandths, I think you should get at least 20 reloads per case with normal pressures without annealing. Maybe more if the difference is less than 3 thousandths. [/QUOTE]
