Is anyone using this stuff in a high pressure cartridge? I am looking at swapping my WBY 30-378 cases to Hornady if they are uniform and tough like the Rem 300 RUM cases. Thanks

By "high pressure" do you mean in excess of 60,000psi?

Yup. I load some full-throttle 5.56 loads with Hornady brass and they are doing fine. Primer pockets are still tight after 3+ loadings, no splits, and stretching about the same as any other brass..

It's my preferred brass these days.

Cool I have to get a few and see if capacity is similar to the norma stuff weight etc. They are 20-30 dollars cheaper than the Norma stuff
