I know which head stamps are usually in the 97-100+ range and I keep them separate from the 90-95 gr brass.
Close enough for me, I load different bullets and loads in the heavier brass just so I can tell at a glance.
it gives me an excuse to have a couple of different types of loads. I found Nosler brass to be heavy also.

I would have got him too but a Dad Blam snow flake hit me in da eye....
