[QUOTE="Canadian Bushman, post: 1047784, member: 41122"] Brass must be fully fireformed ( at least one or two firings ) with out being resized. You can leave the spent primers in or remove them and put them in backwards. I clean cases thoroughly in ultra sonic cleaner to remove carbon build up. Water alone has high surface tension and will form a positive or negative meniscus at the top of the neck skewing results. Use alcohol or water cut with alcohol for better consistency. After weight sorting and volume sorting thousands of cases i deemed it a waste of time for the shooting i do. Too small of variance. Easily drowned out by other variables. Consider this, a piece of brass is .01" longer than nominal and another is .005" short. By measuring up to the neck with a heavy medium as water you derived two different volumetric values and culled one of the cases. In actuality the bullet takes up the space where the deviation was found having zero effect on the actual function of the case. My point? Unless all other variables are controlled to similar standards you results will not change. I.E. Waste of time. [/QUOTE]
