It is very inconsistent between and within headstamps so dont expect "BR" accuracy

Well that's something I've heard loads of people say... thicker walled...

I've just read a bunch of articles where some people have actually weighed, measured, checked the internal case volume etc and basically... they seemed to think there's no difference. In fact there's more variance between the civilian brass brands, and Federal came out on average heavier than the military stuff. But more people are saying there is a difference.

The below article was one but that's referencing 223/5.56 so probably isn't applicable.

Is 5.56x45 military brass thicker than .223 commercial brass?

I really want to know the truth to it. I've got a whole bunch of this stuff and I'm planning on necking it down to 7mm for my 708m for a combination of funsies and because some of my other brass is getting a bit tired.

I'll do some checking myself. Gotta find the time to have a play with it though.

I missed that bit, for a bolt action 7mm-08, you may have to neck turn the brass if necked down.
