I can find volume difference between various brass makers, link below for example from thehighroad.org. That does not translate to grains super easy. When looking a load data from Hodgdon for example in the link also below, it is stating Winchester Brass. It has a larger voume thant Lapua so pressures are different. I am trying to get a sense of the MAx load scaling. I tis less but i am unclear waht less is. Is it 1.5 grains or 5 graisn for example. If there is a resource that lsits that brass load difference I don;t have it, I would liek it. Let lme know the reference name and I willl get it. Since I don't have it, I figured those out here would have direct experience. What the scaling of min and most importantly max for Winchester Brassto Lapua Brass when one has published data for Winchester Brass? I am understanding a 5-6%% reduction for example going from 46 to 43 grains for example going from Winchester to Lapua. Looking to confirm that information out here as well. Thanks.
