Does that apply to different years of Lake city brass or are you referring to the same year head stamps?
I have checked the weight of some years of LC brass and the weight varies as much as five grains. Does your finding mean that the volume of this brass would still have the same volume? If...
I have been using Lake City brass in my DPMS LR-308 with the 24" heavy barrel and 1/10 twist with 178gr. A-Max It has shot 1\4" groups consistently from 100 yrds.

I have been having a hard time finding cases in a box of brass that don't vary several grains. It seems that by the time I sort through it, I end up with as many different weight cases as came in the box. It is hard to have enough of the same weight cases to make a up a set for a match.

I have been shooting the brass form all the Fed. GMM 175gr. that I had purchased when I first got my LR-308. It is okay but I would recommend sorting it by weight. I have found quite a bit of different in them. I did not buy all the FGMM from one lot and there is several grains different in them.
Wideners has Hornady 150 gr. bulk for even a little less than the m80's.
