I realize I am late to the thread....that said.
Over the past two years of have fired over 10-12k of PCs 9mm 115gr FMJ for use in USPSA matches, I have only had very few issues.
1) I actually had a brass casing that didn't have a flash hole in it, no way for Dennis or his crew to have been at fault for this, none.
2) I had a case of 9mm that was obviously underpowered, wouldn't cycle in my G34 at all, but it would run great in a buddies M&P9. We traded cases, his case was also PC ammo and it ran fine in my gun. I spoke to my source of the ammo to pass along my trouble to Dennis, and explained that there was no need for remedy on my part but he might want to check his QC and crew. My source later told me that Dennis was pretty pissed off at his crew and he will "take steps" to rectify the problems. IMHO, that is completely acceptable.
3) I had a case of 9mm 115gr FMJ that was labled incorrectly, it was actually 124gr FMJ. No big deal really as it shot to the same POA in my G34 as the 115 gr load, I passed this info along to my supplier to make Dennis aware of the small issue.
Things to note, before I started using PC ammo I used a lot of WWB and had WAY more FTF, inconcistant accuracy and inconsistant OAL.
Dennis also was a match sponsor for this years Indiana State USPSA match, and for that I thank him greatly.
I think Dennis runs a very good outfit with the small inevitable small problems that are normal in any production based biz. And, while I just bought a Dillion XL 650 to roll my own, I will also continue to use PC ammo when and if needed.
