I am fortunate enough to have friends that work at a LGS with an indoor range. On top of that I have been collecting brass for weapons I may some day own. Now I'm working on 308. I have been able to get my hands on a variety of 308 brass in quantities of 300+ of each. This includes military and commercial.
I have read here and in other forums to sort by head stamp. That is already done. The brass is sized/deprimed using the same die for all brass. All brass are trimmed to 2.005" with an RCBS 3-way cutter. All the brass has been weighed and grouped in 1 grain increments. Example 174.0-174.9 .
The Lake City brass ranges from the 1990s on up to 2015. I have been led to believe that military brass like Lake city should be grouped by year. Rather than doing it by year I have been grouping by weight. I plan on checking the volume of samples from all weight group cases using a fine pistol powder like H110. Basically fill to the top and transfer to another in the group and again and again. This will be done on Mil and commercial brass. I also plan on comparing volume capacity between brass groupings where the different head stamp cases have the same weight grouping.
What spread is acceptable to you in case weight when sorting. Is 1or 2 grain difference in case weight critical?
Is this something that may have been tried by one of you reloading gurus?
Is what I am doing a waste of time?
I understand that the ideal scenario is to buy bulk new brand name brass and work with that. I have the time and I have the brass to do it this way rather than spend the money I like doing things that may buck the general consensus.
Thanks for any and all input.
