So, recently I purchased a bulge buster kit and a 9mm Luger FCD. I've had a few 9mm cases that had given me some trouble, presumably all range pickup brass. So I go to push a piece that refused to enter my gauge after sizing through my bulge busting setup and I remark how difficult it was to push it all the way through. I decide to lubethe next one. And again notice the difficulty of pushing it through.
At this point I disassemble the bulge buster. The two pieces of brass show sizing down the entire length, even the rim and mid-body are shiny from sizing. A micrometer verifies that the base has been sized to .381 (spec is .391). A look inside the 9mm FCD shows an oversize carbide section with a slightly visible taper. At this point I turn to the internets and discover the a 9mm Makarov FCD is what is used to bust bulges in 9mm Luger brass.
The two pieces of (now undersized) range brass are destined for the scrap heap. Learn from my mistake.
