I've used a bunch of it in both 9x19 and .45 ACP, and quite a bit of .32 ACP ball. Never had any issues with any of it. Once upon a time, it was cheaper to buy their generic ball than it was to reload, so I used it for about all of my practice, plinking and training. Good thing I salvaged the cases, which by the way are of very good quality and hold up nicely to repeated reuse.
