Go with something Lapua makes brass for. Better quality means better accuracy.
I used to believe this also. Now, I'm not so sure. I originally bought Lapua brass for my .260 and it shoots better than any rifle I've ever owned. I attributed some of that accuracy to brass that is incredibly consistent and beautifully made. Just recently I bought a considerable amount of Winchester 7-08 brass, which is about 40% the cost, and formed it into .260. I did not sort in any way, and the worst group from virgin brass was .625", with most being in the .28-.32" range with one group at .160. All different loads. If this brass holds up, there will be no reason to pay the price for Lapua. I do have over 10 firings on the Lapua brass and the primer pockets are just getting to the point where I don't wince when I try to squeeze a primer into them.
