I've used their brass in other calibers and never had a problem with it. I like it because I can get new brass for my european WW2 guns without having to pay the $1+ per piece that Norma and Lapua charge.
Well, for another $20.00 or so, you can get the Hornady. I haven't tried it yet, but Prvi I've tested in other calibers would lead me to use the Hornady.
