    Hi, welcome.

    Lot's of info here, as you get used to the site, you'll start picking up on a few details. This thread has been dormant for almost a year, you may or may not get a response. Especially with a fairly uncommon round like the 401.

    Not a bad thing to resuscitate a semi-dead thread, I've done it myself on more than one occasion. I like the idea of trying to keep all the data for a particular cartridge together. Makes life easier if you're researching a cartridge that is new to you.

    Especially ones that 98% of the world has never heard of. Like a 320 Bulldog or a 280 Ross.

    For the 32 WSL brass, I use 32-20 brass.
    35 WSL I use 38 or 357 brass.
    351 WSL I use 357 brass.
    401 WSL I use 414 Super Mag brass.

    I don't cut extractor grooves in any of the brass, and they all eject perfectly. These rifles are pretty forgiving. Accurate Molds has a mold for each rifle.
    The trickiest part is reducing the rim sizes without a lathe. A drill press and file work fine.
    Make sure the buffers and springs are in good shape or things might crack.

    We went the 7.62 x 39 route as there were no excess 414 SM brass available. We shoot the 414 SM in a Dan Wesson, Contenders and a Marlin 36 bored by JES.
    The 7.62 x 39 brass is easy to form up.

    You also want to consider a brass catcher as those 1910's throw brass near as far as a cast slug.

    Is this the method you use to form the cases from 7.62x39?
    I tried with no luck at all. I'd like to try again.

    "7.62X39 to .401WSL.
    1. Run the well lubed 7.62X39 case into a .41 mag. sizer die...it won't go all the way, just up to the solid head of the case. When you withdraw it, will look like a mini-belted mag. case.
    2. Remove the belt. Lathe would be nice, but you can do it with a drill press and a file. DO NOT reduce the rim size...with the body reduced, that rim-less case will be come a semi-rim and you need that semi-rim to headspace.
    3. Fire form load: 7gr. of Bullseye, fill with grits (or cream of wheat), plug with bulllet lube to compress it slightly, point in a safe direction, and fire. NO BULLET! You'll eject a nearly perfect .401case.
    4. Trim the cases to an even length. This is usually a bit less than the 1.5" recommended, but it's better to have them all even at 1.45" than uneven at 1.5"."
