I understand there are quality differences, and one rifle may prefer one brand over another. But that’s not really what I’m talking about. When you look at reloading manuals, how strict must you be with regard to brass and primer brand? Of course my Nosler manual is going to call for Nosler brass, how big a deal is it to use Federal or Remington brass? Of course, sized and trimmed to spec in both cases. Same with primers... if one manual calls for a CCI 210, can I safely sub in a Federal 210? Or must I adhere to the manual to a tee? I’m trying to minimize the number of components I need to purchase. Thanks.
