Does it withstand pressure reasonably well? Are the necks consistent? I'm considering a 300 RUM build but I haven't been able to find much in the way of reviews for this brass.

Thanks!
 
Il be buying some soon to do load development for a friends Rem 700 sendaro 300 Rum. I also have some 338 edge Bertram brass that I want to neck down and try. Tested some of the Bertram in the Ol Edge IMP and it held up well. The Norma brass might have better tolerances but it will be softer than Rem or Bertram. That being said I'm going to try some myself.
 
I bought it on gunbroker same price as through ADG. The price diff i saw was VS. Midway's price on Norma brass
 
I was splitting necks on Remington brass. Norma has done great for me so far.
Can you guys elaborate on ADG? What would you compare it to?
 
shot some ADG 338 rum to fireform for a test this weekend I will stick with Bertram and Norma.
