There was a time not too long ago when I didn't even consider reloading 9x19 because Blazers and several brands of generic, NATO-spec ball could be had for less than the price of components. I went through a lot of Blazers, S&B, Hansen, etc. back then (heavy sigh!).
Never had any trouble at all with Blazer 9x19 or .45 ACP, which were what I bought the most of. I ran nearly 2300 rds. of their .45 ACP through my Springfield Champion during a 5-day course at the Chapman Academy several years back with nary a bobble that wasn't deliberately set-up for an IA drill. It hit where I pointed the muzzle and I didn't have to spend any of the shooting/training time I was paying for scrounging up empty cases.
The new paradigm for me is two dedicated SDB's and paying the extra dollar per box for Blazer Brass when Natchez, et al, is running a deal.
