[QUOTE="freddiej, post: 1749201, member: 26227"] Brass prep that I have seen that is always a good idea or an excellent idea; #1, uniforming the flash hole, centering it as well. #2, neck turning or neck reaming your necks. now I neck ream. this is because RCBS at least used to make a special sizing die that allowed you to put a specifically sized reamer to make your necks, concentric, and set at minimum useful thickness. this kind of neck prep made several rifles go from 2+ MOA down to less than 3/4 MOA without anything else. with load developments I achieved 1/2 MOA or better with several rifles. Yes, I am a devoted neck reamer for all cartridges I own reamers sets for. #3, trimming to a uniform length. I like to split the trim to length and the max length and trim a bit more often. #4, volume, there are two ways to do this. one involves a liquid in your cases and weighing them twice (once dry and once filled), or you can weigh them once dry. depends on the school you come from. I will use either one. #5, always fire and resize your brass before uniforming your brass. brass stretches in wild ways the first firing. #6 set your dies to size your brass 0.001 to 0.003" under the chamber length to keep stretching and over working your brass. #7, anneal after every other reloading. at least that is what I do and it keeps brass around much longer. later tatters.
