    I pick up a range brass when it presents itself and right now I'm going crazy because I'm hitting so many crimped primer pockets on 9mm brass...really gumms up the works when I'm loading on my turret press.

    Any way to visually ID which brass has crimped primers?

    Yep, you look at the head. Crimped in primers have a crimp around the outside diameter of the primer pocket. How does it "gum up the works"? Harder to deprime?

    Well, generally you just look at them.

    There will either be a depressed ring around the primer, or a few stab crimps.

    when you look at the primer you should be able to see the crimp "ring" around the primer. Are you sure you aren't getting bredan primed once fired? Look inside the case and see if there are 2 flash holes in the bottom of the case, if so throw then in the junk bucket

    They are boxer primed, brass shells.

    It gums up the works because the new primer won't seat. I have to take the case out and use a primer pocket reamer to cut the crimp out.

    The photos above tell the story. I have had some that you couldn't see without very close inspection, but most are pretty obvious.

    9mm brass isn't scarce or valuable enough for me to worry about salvaging brass with crimped primers.

    Look at the headstamp. I find the crimped 9mm is usually WCC (Winchester Cartridge Co) with the year of manufacture- "WCC 10" for example. Military brass doesn't say "9mm Luger" in the headstamp either. I hand sort my brass, any military 9mm I chuck in the scrap bucket on general principles. Life's too short to bother swaging or reaming 9mm brass- there's just too much of it around to waste that kind of time on it. I sorted 5 gallons of just 9mm/380 brass last week and had an overflowing quart tub of 1X fired WCC 10 & WCC 11 brass that all went into scrap.

    His problem is that when he gets a case that has a crimped primer, the primer pocket needs to be swaged before he can seat a new primer. Duelist, you will need to visually sort the brass before processing it, and get a Dillon Super Swager if you have very much brass.

    I'm lucky at my ranges. I "only" use 9mm range brass but stick to "Win, Fed, F.C., *-*, Speer, PPU, R&P and a couple of others that don't come mind right now. None of these are crimped. The PPU primer holes are a little tight but not crimped.

    WCC, WC and and S&B (some S&B are brass plated steel cases) are not worth the hassle.
    I have over 15K deprimed and tumbled cases ready to load.

    I have NEVER bought a 9mm case and I shoot 200+ 9mm rds/week avg.. I have 15,000+ 9mm cases deprimed, tumbled and 'ready-to-load' stored in coffee containers marked by headstamp.

    "Win" is my preferred 9mm case. (Or maybe nickle plated Win). ;)
