Re: Brass !!
I have no experience with Norma brass.
I have Nosler and Winchester. According to the Nosler tech I spoke to at the time, their brass was made by Norma (not necessarily still true).
Nosler brass was as close to perfect as I can imagine. 250 rds. within less than 1gr. All exactly the same length with round necks of even wall thickness with less than .001 runout. Primer holes were deburred and chamfered. I have over 10 firings in my 300WM (some very hot) and this brass shows no signs of giving up the ghost (probably due for annealing, starting to get some neck tension variability)
I recently purchased 300 rds. of Win. brass. In one bag the weights were centered around plus/minus 1gr, but varied up to 5gr total. No prep work at all (normal). Necks were horribly out of round and thickness varied from .0115 to .017. I turned them all to .0125. I have yet to fire this brass, as the Nosler is still giving me great performance, but will start cycling it soon for spring load development (case volume difference from Nosler). I've been told it's very robust brass. It was the only brass available when I bought it.
