I'm much, much more alarmed at your addendum regarding the Hornady brass than I am about any part of your rant on the R-P brass. R-P brass has seriously dropped in quality in the past handful of years... like an epic landslide.
PMC is bad these days... a shame, because I have some 90's era PMC 10mm brass that is terrific. A-Merc isn't brass, IMO. It's an imposter. It may look like a cartridge case, but it's just scrap metal.
Attention Brass rats and other reloaders: I really need .327 Federal Magnum brass, no lot size too small. Tell me what caliber you need and I'll see what I have to swap. PM me and we'll discuss.
