I've got some fire formed federal gmm in .308 consistently measuring at 2.008 and I've got some fire formed winchester power point in .308 measuring from 2.002 through 2.008. All of the brass has been fired out of my rifle. Will this effect my loads if I reload it? Standard .308 cartridge is supposed to be at 2.015. I thought the brass was supposed to grow and be trimmed back to 2.015. My calipers are calibrated with a machinist 1,2,3 block I have. Please advise.
Thanks,
