I can not speak for .308 as I do not load for it. I do load for .223 and used the OCW method with matching head stamps, and then just as a curiosity did it again with mixed head stamps to see how much of a differance it would make. The results were that the loads were more acurate than I can shoot.

Though the variance between .308 and .223 is probably a big one.

I rember reading part of the reason for his method was you would find a load that could go .3 grains either way with consitantly similar performance if you changed to a different head stamp, or lot of brass.
