I’ve never rolled my 9 major brass, but I only use the same brand. I just sort out the Blaser cases from my range pickups. Size them in my RCBS sizer, but run them through a Lee crimp die with the carbide sizer ring in it. I’ve never had a feed issue yet. I use them once or maybe twice then dump them. I only use the Blaser brass for my 9 major loads, that way I don’t mistakenly use them in any other 9mm pistols by mistake.
