    I reloading some 9x19 now on a single stage press. In the process of charging some cases I set one case next to another and it was visibly shorter. The shorter case is a Sellier & Bellot. It measured .716. I measured a handful of cases and most are close to .750. What's the minimum case length that I should keep before I consider a case garbage?

    Max Case length is .754".
    Trim Too length is .744".

    .716" sounds like a .003" too long .380 ACP!

    I like to stay around 0.750 for my Lengths. What you have there is closer to a long 380 auto (9mm Kurz).

    With the loads I use, I would just put that one in the scrap bucket.

    Awe... RC, you beat me to it. I was in the middle of answering and my wife asked me to help her loosen a jar in the kitchen.

    Sounds like someone trimmed a 9mm down to use in a 380. I have run into it before a few times and would not think it is a good idea to do that. Crush it with vice grips and chuck it in the scrap bucket. Now it can't be confused with good brass.

    You can't trim a 9mm down to use in a .380 ACP. They are much larger at the case rim.

    What you can do is trim them down to use in a 9x18mm MAK.

    Case length on them is .713" and the head size is basically the same.

    Yea, weird. It says 9mm on the headstamp. I'll chuck it. I went through all the other S&B brass in the batch I bought and they were all good.

    I'm curious as to what the headstamp says. Is it a 9mm Luger? Is it the same as any other S&B cases you have? It could be a single error in that lot of brass.

    As rcmodel says, it can't be a .380 as they are much smaller (relatively) in all outside dimensions.


    [Edit]
    mms posted as I was looking at dimensions and composing. ;)

    Was this used brass you got somewhere?

    If so, it is a 9mm someone trimmed to use for a 9mm MAK pistol.

    People do that for some reason, and as you found out, it is a royal PITA when you find them mixed in with 9mm range brass.

    Bear in mind that S&B .380 ammo is headstamped 9mm Br. C. (Browning Court)

    Looking at some I have found, the headstamp says 9mm M on it. Guess that is a makarov. Ooops. :(

    It says S&B 9mmM. I guess it's 9mm Mak

    Amazing what one single little character makes, eh? As you surmise, that is a standard 9mm Mak case that got picked up with the regular 9mm Luger cases. No trimming was involved.
