    taralon-capacity is 355gr water.
    spiggy..we plan on getting pics and video
    when good weather gets here.

    Antibubba- this even, as big as it is, isn't
    ultimate stopper for game, bunch of us are going to
    make 2 and 4 bores.I also have 700HE with more
    power to test in a couple months, and down
    the road the 900HE.Here is pic for
    your pleasure, of 4 our bore cases,
    with 2000gr bullets, next to 20mm brass we make
    them from, and 06 case for comparison.Ed.

    The ATF is okay with a 4 bore? The letter I got from them said it'd be a DD...

    On the bright side, it'd be almost impossible to lose your brass....

    Others have built 4 bores and haven't even had to deal
    with atf or even bothered by them.In fact colarado guy built
    some in falling blocks, guy in TN built some in doubles,
    guy in AK built and was written upin magazines,distributor
    in midwest imported and sold large number of 4 bore russian
    pump guns, and I know 2 guys who have them and haven't been bothered or do the registration bit, with 200buck tax.
    If it becomes an issue we will just send in papers and get it registered as sporting use like I did my 700. ATF isn't
    all on same track, but the one dept that checks over 50cal
    stuff for sporting use/dd exemption has approved all that
    have asked.Ed.

    Actually, he was from the NWT, but AFAIK, as long as its solid slug and not explosive, large caliber are fine. I think there's a limit on case capacity.

    Mike--I think limit is 1/4 lb of powder in the case.

    Title 18 Gun Control act -
    Sec 921 (a) (4) (B) says in describing a DD, says

    any over 50cal, except shotgun calibers.

    So that covers all bores from 2 to 28 bore or gauge.

    Then has exemtion in part (C) that says any over

    50 cal that they determine is antique or sporting.

    And that last is what we get stuff registered as sporting,
    that isn't gauge or bore sizes over 50 cal.

    You send them aletter requesting an exemption for your
    cartridge,asking for it to be registered for sporting use.
    Also include a description of the sporting type
    arms used in, like break actions, falling block actions,
    bolt actions. Must send in drawing of case with dimensions.
    Then wait.
    Back to 12GA from Hell--Here is pic of case in a
    modified Martini Greener..Sometime will try to build a heavy
    wall version with changes to use case in.By building
    wider and thicker, can change pivot hookup, it will handle
    long case, It was originally regular 12ga action.Ed.

    rims shown in pic.Ed

    I thought Rob's Borchardt actioned rifle looked familiar, then I ran across a photo of it's greatgrandfather. Only 5000 pounds, maybe I could find a couple of guys to go in on it.

    What is it? Cogswell & Harrison 8 bore falling block. Nitro proofed, but for round balls. An old school beauty, I posted the pic to show just how close Rob's gun follows the work of a London gun makers falling block single. I think the family resemblence in uncanny.

    If you do your own work on building one like
    Rob's, you do for lot less than that...And that
    Borchardt is nothing like the old, in fact it
    is big enough for a 10-8-4 bore/gauges.Ed..

    of the bolt is to camera and up where top lug
    is and I wanted to show extension
    added to left lower lug that holds case along with
    top lug extension and extractor on opposite side...Ed

    Wonderful rifles. Well done! How many times can you reload the cases before they become unusable?

    Also, I'm wondering about the 4 bore's bullets. How on earth do you get jackets for that large a bullet? In the pic they look similar in shape to slugs, but larger and jacketed.

    Balog--At pressures in my gun, max 30-35,000, never wear
    them out.Have to anneal top third every 50 rounds.One fired 33 times and no sizing needed on bottom half.

    For 4 bore bullet bullets they use big hydraulic
    press(A Corbin) to make jackets from copper sheets
    and then to press lead and jacket together.Also there is
    a company that now makes jackets with a huge factory
    stamping press, supplying bullet makers.Ed.

    I can't get that site to come up. Looks like another stack of stuff for http://www.skippyslist.com or my addenda at http://www.michaelzwilliamson.com/rants/skippylist.php

    But yes, my oath DOES in fact authorize and require I start a revolution if called for.

    And if shooting tree down makes for a herd of
    mad squirrels you've got a stopper.Ed.

    Some have been mentioning using guns with lenghtened
    chambers and our case for deer in shotgun hunting areas.
    Already been fired once in an Encore 12ga. There was a
    discussion of game wardens. etc. Well most shotguns
    smooth and rifled have 12 GA and the length stamped
    on barrels.There is 2 1/2, 2 3/4, 3, 3 1/2, so I say
    stamp ours "12 GA 3 3/4 FH". Any thoughts from folks
    here about this.Ed.

    Stamp it 3 3/4" MAGNUM or something very distinctive. It's no ordinary shotgun round.
