Re: BRASS Norma vs. lapua
When I first started doing load development with a 6.5x284 I used to have I started with Norma brass.
I could not achieve reported velocities with this cartridge and was showing major signs of pressure. Also, primer pockets stretched out prematurely.
I switched to lapua brass, and all my issues went away.
Norma brass is thicker, it might be more robust, but i doubt it based on other cartridges I have used it for, versus lapua brass.
IMO, lapua brass is better.
