My preferred brass has always been Winchester, with Rem second or third. I only purchase Hornady brass usually because its the only brass around for some of the weird cals, like .404Jeff. In semi auto rifles Win has always worked better for me, get better case life over the others. Prvi is pretty good, though S&B tends towards early neck splits. Never used Norma or Lapua, too expensive. Federal I get mixed results, great in pistol cals, so so in rifle cals. Tends to show incipient separation (bright ring) sooner than Win. I have an M1 Garand that only gets new brass when the rims are so battered I cant stand to look at them anymore, Winchester brass. Never had a bright ring or separation in that rifle with Win., ever.
