    Looks like a fun round.

    Even like the name, kind of like the name of the road leading into Shanghai from the airport: English translation on the road sign was Long Dong Boulevard.

    24 GAUGE CBC shot shell brass is easier to do, in making them.

    post# 29, reminds of WARREN PAGES, I believe, PAGES SOUPER POOPER? I might be confused about the case?

It was long enough ago that I had to decide whether to make it a .411 or a .416. I chose the .411….
    I did the same thing, but used 308.
    I wanted the shorter action, and the reduced case capacity was a good thing… With 41 cal molds easily available in weights from 175 to 350 it was a perfect option for a fan of the caliber with a good selection already on hand.
    I chose 2” as the case length, but it could easily be shortened to 1.75”-1.8” and be legal in those States requiring straightwall cartridges with length restrictions.
    It was nothing more than miniaturizing Nonte’s 458x2” American concept for less “OOMPH!”, and still be used in a good bolt-action, staggered magazine carbine with nothing more than a barrel change.
    A .40”+ cast in the 250-350gr weight range at a sedate 1600-2000 fps is more than adequate for anything I’ll ever need, and will play pure Hell on stubborn aluminum cans that the tiny .224’s zip through with barely a flinch.

    Being able to chamber the barrel without custom reamers, and reload the round with commonly available dies (240 Weatherby and a shortened set of 405 Win) made it too attractive as an experiment.

    These were early prototypes…
    .375” on left, .412” on right.

    30-06 to 9.3x62. I'm not very adventurous.

    Evening, can you provided more info on this cartridge??? I was trying to achieve the same round. What kind of chamber pressure?? What is the COAL?? Is 2000 FPS achievable from a 16 inch barrel? Also.....C4HD makes a die set to form 240 weatherby brass from 30-06 brass forming the belt...Ever try to use this one??

    6mm Lee Navy from 30-40 Krag.

    Neck to 7mm.
    Neck to 6.5mm.
    Neck to 6mm.
    Anneal.
    Turn off the rim.
    Turn base diameter to approximately .446 from .457.
    Cut a new extractor groove.
    Bevel the rim, which is necessary to work with original clips.

    Convert .17 WSM rimfire to .25 Stevens rimfire.

    Pull bullets and dump powder.
    Trim to 1.20
    Anneal mouths (ANNEAL? How do you do that without setting off the primer? My secret!)
    Expand:
    First step .170" to .190"
    Second step .190" to .215"
    Anneal again
    Third step .215" to .240"
    Trim to length 1.125"
    Fourth step expand to .257 I.D.

    Tedious, for a case that would normally be used only once. Some still split, but I'm getting about 80% good ones per box.
    And there's a kit on the Innerwebz that you can use to re-prime the rims.

    WooHoo!

    That's why I started this thread!

    For CRAZY PEOPLE!

    Keep the old and weird shooting.

    It would be even better if you used the powder for pyrotechnics....


    But please don't take the secret of annealing primed rimfire case to the grave.

    That's way too important information to disappear.

    I was in an LGS yesterday and spotted some .17WSM on the shelf. I bought 2 boxes just to put away for this purpose. I dont have a .25 Steven at present, but its good to be prepared
