Well, guys, all that conversation just seems to reinforce the thought that you should fire a lot of ammo and then pick the one your gun likes. Some guns like anything no matter how good or crummy. Others are like royalty, they seem to prefer one brand. I did find one remington round (10mm) where the case was a bit longer than the rest. I also found one box of "white box" Winchester that gave me five rounds from the same box that failed to ignite. But those were the only "bad" rounds I found with any brand I've tried. I shoot a lot of Blazer, reliable, accurate. My preferred carry is S&B.
