223 Brass weight by head stamp

All SS Pin cleaned, sized, trimmed with a Giraud tri-way in a drill, SS Pin cleaned again, weighted.

I have 10,000 cases gathered over the years, next I'tll test a few together, see if my rifle and I notice anything different at 200, the longest range I have access to. I believe USA is the new budget Hornady ammo but I have not confirmed that yet. The Norma is all from Norma Tac., which I like a lot.
