I've used a bunch of different brands of brass.

Lapua and Peterson were likely the best I used.

That said...I used a BUNCH of Norma...after they opened a plant here in the states.

I could usually find their Whitetail line of ammo on sale for less than I could buy the brass for.

Easy decision. It also gave me the opportunity to find out that their loaded ammo was extremely good. So good that I ultimately gave up hand loading and just use their ammo.
