First, I like brass if it lets me shoot. And especially if I can use my standard loads.
Secondly, I've had many experiences that are different from those on this forum.
For example, I had one batch of Norma in 416 Rigby. 59 cases were 327-330 grains and 41 were 337-340 grains. Go figure.
Then I had a bunch of 338WinMag Nosler brass and a bunch of them started showing up with split necks.
Go figure.
And, I've used Hornady with happy results.
First, they keep 416 Rigby in stock.
Secondly, they do 375 Ruger.
So thirdly, I've been using them for 270Win and 338WinMag, too, with only good to say.
Finally, I'm happy with Lapua. I've got some in 308win. But I don't see much difference, YET, between them and Starline, except price.
So give me any decent brass and I'll go hunting.
