[QUOTE="dmax1800, post: 818064, member: 68255"] I am new to reloading. I've read that you need to measure everything and be absolutely consistent. I just got 100 Norma brass in 300 win mag. Just out of curiosity I measured the length of 10 randomly selected cases. They range from 2.06065 to 2.6120 inches in length. Is .0055 too much variance in new brass? Should I trim the new cases to get them exactly the same length before firing them for the first time? Will the variance in length effect accuracy is my biggest question. I know that you should trim the cases during the reloading process after they have been fired. I have the inserts to measure the chamber length. Thanks. [/QUOTE]
