    I must have picked these up at my range. I had a few, but not all, fall down inside my case gauge as you'd expect a .380 but they are stamped 9mm?

    What do you mean "fall down inside the case gauge" ?

    Are you case gauging empty brass ?

    Is it a piece of reloaded ammo that is going further into the case gauge than you expect it would? Because... guess what, if it's doing that, that's how far it's SUPPOSED TO FALL. The 9mm cartridge headspaces on the case rim, not the base. You can put a 9mm cartridge in the gauge upside down (base first) and it will go inside the hole.

    That was something I didn't realize at first myself. But a properly resized and loaded 9mm round, the base of the cartridge will actually be slightly BELOW the surface of the gauge.

    These are reloaded, not empty brass. I have probably reloaded 8-10,000 rounds without seeing this. The round is about 1/8" inside the gauge! I had a few .380 pieces slip thru & get reloaded with 115gr tips & when you case gauge both rounds they BOTH fall down into the gauge.

    Thats why I've never owned a case gage, afraid I would find too many problems.
    I treat my reloads like a Postal flat rate box,,
    If it fits it ships!

    Why doesn't S&B just stamp it .380? Any other manufactures utilize this designation?

    FWIW get out a magnent, a lot of 9mm S&B brass is just plated steel.

    Thanks! That would be a quick way to weed them out.

    No worries. Had this problem myself. You will also see 380 brass stamped 9x18.

    Shouldn't this be 9x17? IIRC, 9x18 is only used for two cartridges, the 9 mm Ultra, and the 9 mm Makarov.

    .380 may also be stamped 9mm Kurz.

    Not trying to be mean/harsh. I just don't know how else to say this. You need to pay better attention when you are loading. You should have noticed the minute you pulled the handle on that 380 case that it wasn't right. It would have been noticably easier to pull the handle on that brass. The minute you feel things not right you need to stop and find out why. That is a good reason to never size a small batch of case seperately and just throw them in with the unsized stuff that you plan to load. You will train yourself to ignore those "easy to size" cases. Then the bad stuff can slip through. Those 380 cases are not sized. So the bullets are not being held in very well. Don't assume that they won't fire in the 9mm. The very well could. I fired a 9mm in a 10mm gun. 380 is pretty close to 9mm. You could also easily have bulet setback and ou already have a much smaller case so it would be a very bad thing if that happened.

    There's also 9mm(M) for Makarov. Sneaky buggers. I've found anything before the date code '10' is usually steel. But not always. Sometimes.

    9mm Corto is Italian for .380

    Plus the likely won't headspace correctly or seal in the chamber properly. Breechface and gun will take a beating with those rounds in there.

    OP needs to check his brass a little more carefully. Spot on about learning the feel of the press/round. Something doesn't feel right stop and figure out what's wrong. It's a whole lot easier while there are 4/5 rounds in the press than 1000 rounds in the bin.

    You are absolutely right, advice taken. I do realize the seriousness on loading that .380 especially since I shoot mostly full auto.

    It just so happened that I used Hornandy spray lube on that batch at the urging of Murphy's Law, and associated the ease of the handle due to the lube.

    I submit myself to the mentoring of you and all the members that know a heck of a lot more than me. Please keep the corrections coming when I need them!

    I always run every round thru my case gauge as a final safety net.

    The smartest and safest thing you could do as you travel the path of your loading career is to stop taking advice from anyone called, 'Murphy's Law'. :whistling:

    That's like asking me for marriage advice... it's not going to end well.

    That does the trick alright. I case gauge all of my competition ammo but with the brass sorters and case prep equipment I have, I don't bother with my machine gun ammo.
