    That US-S pointed slug with discarding petals,
    and locked on base, shown above is called the
    Swift 12. And correction on the weight, it is 320 gr.
    And they plan on testing and maybe supplying 3.5"
    versions, planning on getting around 2500 fps with
    shotgun powders. I know in our 3.85" case in the long
    barrel Savage, I could get over 3000 with big amounts
    of our slower powders we load with.

    Bought some tubing caps And here is picture
    of those copper tubing caps, you can make bullet
    jackets out of, and fill with lead. In picture you see
    a rough one I formed with punch, and with a die they be
    perfectly formed. And with right die they could be
    formed with round nose with edge step for perfect roll
    crimping in plastic. And on the right see big caps that
    would do 4 bore.There are caps between the two sizes
    that would do 8ga...Ed

    More 12gs slug/sabot info-- About discarding sabots.
    Most factories making sabot slugs make them relatively light,
    300 to 350 grains, and that is why they are on average
    more accurate than what guys try to reload with heavier
    slugs in the sabots. Reason is light slugs don't damage
    the sabot, while they are trying for high velocity.
    Example is picture of Hornady SST sabot and it only has
    a one way plastic seal over powder, and a hard
    rubber cushion inside the sabot under the 300gr jkt
    spitzer style slug. Many 12ga hunters say these are
    the most accurate.

    Another slug idea is a blunt nose jacketed slug of
    675gr I made from one of RG's hollow point jkt slugs.
    I cut part of jacket off of the front and swaged
    it over to make blunt nose. These are for the guys
    trying to make short loaded brass case rounds
    in 2.5" brass and 2.62" brass to be no more than
    2.75" overall to work in certain guns. it is
    on left, 2nd pic. And gets good velocity with just
    good BPGS seals under it and slower powder.
    On right is US-S sabot with discarding petals, locked
    on base we tried in short brass case, and can't, due
    to length of sabot get in enough powder to get
    the higher velocity with heavy 700gr US-S slug, the
    guys want to get.....ED

    Here is picture some folks wanted of our
    big cases with smaller 30-06 for comparison.
    In picture, 1st my 2ga, 4ga, 8ga, 10ga, 12ga,
    my 700HE long case, my 700H 3.25", and 06.

    2nd picture is short 2 5/8" brass cases we
    are checking loads in, to see how much speed
    can be gotten.You can easily see the length of
    short full bore lead slug, compared to the
    saboted ones, allowing more powder in the short
    slug load for more speed..

    Now this doesn't mean saboted are no good, or
    that I don't like these saboted types. Great for
    smooth bores, the US-S with locked on base, are
    the best there is, I think, for big game.Just
    got to use longer cases. I always felt, that going
    longer cases is worth the effort where practical ED

    Here is picture of my big 585 cases.
    30-06 for size comparison.
    3rd is 585HE - I have it in bolt, falling block,
    break, etc, actions.

    1st is 585 Hubel Super Magnum - Designed
    for strong bolt guns. Have in a MRC PH.
    Can get 20,000 ft lbs.

    2nd 585 Rimmed Hubel Magnum and I have it
    now as a single shot in an 1887 Win.
    The 87 has a 30" heavy barrel. Case is
    designed to use in break actions and run about
    25,000 psi, but due to the size of the case
    has enough powder so can get 15,000 ft lbs.
    It is 4" long, and could be called 24ga FH.Ed

    Some 10ga experimenting with slug loads.
    In NEF with 32" factory, long bull barrel.
    It is smooth so we use hollowbase slugs

    Cases FED 3.5" plastic cases, roll crimped.
    900gr full bore slugs -180 gr RE17- 1800 plus.
    Use plastic powder seal and fiber wads.
    Slug hollowbase and hard cast.

    740gr 69cal hollowbase soft lead slug, in VP100
    10 ga wadcup. Deep hollowbase slug ..Wadcup has own seal
    and cushion. 180 gr RE17 -- 2000+ fps.

    Here are pictures of a couple other different guns in
    my long 585HE cartridge.. 1st is Olympic Arms
    BBK bolt gun, in a target style stock with palm
    swell pistol grip...2nd is the one I made on a CBC
    single shot by mono-blocking in a heavy 585 cal
    barrel. Barrels- CBC breach 1.18"-- BBK breach 1.32"
    1.070 muzzles.Ed

    Ed, can you tell me some more about your .700 HE cartridge?

    If I understand things right, it's basically the 12gaFH, except you swaged some of the taper out of the case to provide a belt to set headspace.

    Does this cartridge use the same .72 caliber bullet as the 12gaFH? The only spec I found says the neck diameter is .740, which looks about right.

    If you can point me to a page somewhere where you explain things in detail, I'd appreciate it!

    My state has no caliber restrictions, and the last gun show I went to had new, unfired BMG brass for $2 each... since I have to build the chambering and sizing reamers from scratch anyway, it would be cheaper and simpler to go with the .700 than the FH, as long as I don't have to eat the barrel I already bought...

    My 700 use a .700" caliber bullet, not the .729 12ga size.
    I do have reamers for my 700HE 3.25". And I have dies.
    My short 700HE 3.25", mouth is .740.
    the long 700HE, mouth is .735"- 3.87" long.

    I make 700 cases by machining and swaging, ending with a
    belted case, where on 700HE the belt is .795" - base .775"-mouth .735".

    If you set up 12ga FH with 3.5" chamber, and then you can use regular
    available 12ga 3.5" reamers, and get brass 3.5" cases that fit same
    chamber from RMC.And chambers will take plastic 3.5" also.
    Maybe the most versatle way to do it as long as you
    already have 12ga barrel. What gun is barrel for..Ed

    Some 28ga FH info and ideas.
    Brenneke now has 28ga slugs, with good speed,
    decent smooth bore accuracy. About 260 grain
    slugs. SAme style as their 12ga ones with locked
    on base.Work in 28ga NEFs of course and
    28ga O/Us.Some real good 28ga O/Us out there.
    28ga is a .550 Inch bore.

    But now Rossi has out, a revolving 28ga shotgun
    with about a 19 inch barrel. Should work ok with
    those slugs. You could also get RMC 28ga brass cases
    about 2 3/4" long, maybe 3", depending on chamber,
    a shorter version of our 28GA FH 3.25" case.

    Maybe I get one in the future, and put on a longer
    heavier 585 cal barrel and set it up for my
    585 Short HE. Have a switch barrel 28ga/585.
    Neat gun.Called Circuit Judge....Ed

    I found a picture of 28ga Rossi Circuit Judge. Barrel is
    smooth bore , could be little heavier barrel, but it will do
    ok with the new plastic case Brenneke slugs,
    260 gr at 1450 fps..Could do 2000 in a little longer
    brass case from RMC.

    28ga is a 550" bore in a rifled bore.
    24ga is about .585 same bore as my 585, and
    most all 577/585 stuff. The 28ga chamber with minimum work
    would fire my shorter 585 with a switch barrel 585 bore.
    And still work with 28ga with 28ga barrel put on.
    Difference is the case thickness with the 28ga case
    being nearly the same OD as my 585 drawn, stronger
    brass cases.

    The Brenneke slug has a long locked on base and seal,
    connected by long post, that you can see inside
    the case in picture and pictured on the box
    Quite a long tail so to speak for
    good smooth bore work.This is a great step forward
    for 28ga slugs, as most reloading slug stuff was only
    100 grain balls or other super light slug designs...ED

    Some have a need for supply of full bore 12ga hard alloy
    slugs about 620-650gr. So a couple guys are opening up
    their Lee Key Slug molds to full bore .729" It will still
    have the partly hollow base and key. I will do the
    short brass cases with the first ones I get, to get loads
    developed. The slugs are about same length as
    the 730 gr Dixies.They have blunt round nose and
    can be roll crimped in plastic cases ok. Load of 90gr
    of IMR4759 in the short brass or 3" plastic cases
    will get 1800 plus in 24" barrels.
    I'll Have pictures later to post.

    Also here is picture of my 585HE in a Khan
    shotgun action. Operates as a straight bolt,
    straight pull action for now. Barrel is heavy,
    30" long, the butt is weighted. thick pads,
    it fits nice, looks great. Ed
