[QUOTE="DNADave, post: 1906049, member: 110467"] I think we're getting at the same thing but from different perspectives. I do think there is a weak relationship between the two and that it matters less as the average case volume increases. The brass thickness on a .223 is not proportionately thinner than the brass thickness on a .308 in relation to average volume. It's actually the reverse in that as a proportion the .223 brass thickness is proportionately thicker versus the .308 when compared to volume. This would mean that for a .223, the weight would have a stronger relationship with volume than for a .308. Is it enough to matter, I like data so I would want to look at that data. I think doing the same experiment in a .308 would result in looking at minuscule differences that in the grand scheme of things might not matter. Looking at the .223 data would tell us if that might be the case. If you don't see any effect in something like a .223, I doubt you would see an effect in a larger cartridge. But, as I said, I like data... [/QUOTE]
