I prefer Noslerbut use Winchester and Remington for a few guns. I've found Remington brass to be brittle, inconsistant in weight and thickness, and the primer pockets aren't uniform. I use Rem brass for my 260 Rem. Out of 40 rounds fired I average losing 6 cases from primer pocket stretch and split necks. When I was using Federal 260 Rembrass I never had these problems.
