    Odd range pickup

    Picked up a bunch of 9mm cases...they are ridged on the INSIDE of the case- the step is solid all the way to the bottom of the case... 1- greatly reducing case capacity, higher pressure less powder???? 2- No way to seat the bullet too far in the case, nor will it "walk back" due to recoil... still a bit odd... sorry for the bad photo, will try again with another camera if there is interest... thought it might be interesting....

    Probably from a paint marking training round for LEO training, live fire exercises.

    I think that is a simunition round. the rim may telescope out from the case body if you twist and pull on it. I found some of the same cases in a bucket of brass from my local sheriffs dept range recently.

    FN head stamp? I find quite a few of these in our indoor pistol range. They end up in the scrap bucket. These have been discussed on here before and some say they reload them. the shelf so the theory goes prevents bullet set back.

    I thought Magtech made some 9mm that were like this as well.
    Headstamp?

    Yes, that is maxxtech, it is not simunition or anything else interesting. I scrap it all, as do most.

    There are a few other headstamps that have similar construction, but none I’ve seen are as pronounced as maxxtech.

    Actually it is non-tapered-wall brass. Works fine if you just seat to the ridge. At least it's not the Alum. junk stuff.
    Whatever!

    I would have to take into account the reduced case capacity if I were to reload these. For as readily available 9mm brass is, I would toss it into the recycle bucket.

    Very interesting. I would think that these would be fairly expensive, since they involve much more brass than a regular cartridge and must cost more to make.

    I've found several of these. Some casings are now made of stainless steel. Some are two-part. That inner piece sure keeps a bullet from being pushed deeper into the case. I think we will see more changes to cartridge casings. I do not reload these as the volume is WAY reduced. And, no data is available. I treat them same as steel and aluminum cases. Road gravel.

    I have to wonder about the "WHY" of that. Sure, you have an economy of powder in that you can use less to get the same chamber pressure, but you get that economy by using more brass, which I'm pretty sure is going to cost more than a grain or two of nitrocellulose.

    I also have to wonder about a load workup for that. Sure, there's a smaller chamber, which would give higher initial pressures for a given charge, but then that gas starts expanding into the same old bore, and that chamber becomes a constantly shrinking percentage of the total volume. Hrrrrrrmmmmmmmmmmmmm. . .

    Irritating in the same way that small-primer .45 brass is irritating - non-standard garbage getting mixed into a century-old supply stream.

    I assume that the case is cheaper to produce. Maybe more brass, but less machining? Intend to cut one apart to see exactly how it is assembled.

    Here is a link to another forum that shows a photo of a sectioned case.

    From the draft used on the tooling I would guess those cases formed by impact extrusion.
    The case blank is warmed and smashed by the tool. The metal flows upward to form the case wall.

    With the proper precautions those cases should reload and shoot ok. But as plentiful as 9mm brass is I would probably scrap them. You can find some interesting stuff mixed up in range brass!
