Re: Anyone using military LC 308 brass?
I use LC77, LC75M, and Federal GMM cases. Accuracy in all three is the same, but I have "race prepped" all three lots of brass: trim to uniform length, deburr flash hole, uniform primer pockets.
Using the same load of Reloader 15, CCI-BR2 primers, Nosler 168 custom bullets, the velocity spread (at the most extreme reading) was only about 20fps different for the same load. All were right around 2580-2600.
Although the accuracy on paper was the same for all at 200 and 300 yards, the Federal brass had an extreme spread of only 3fps, so I would bet money that at longer ranges of 600 to 1000 that low spread will give greater consistency, and eliminate much of the vertical stringing.
Mostly, I was surprised that the velocity was nearly identical for all three. I had presumed that the thicker LC cases would have more velocity with the same powder charge, but that didn't prove true for me this time.
I'll bet if you weight sort the military cases, you will get the same consistency I got with the Federal brass.
