    Here are pictures of other guns we have setup.
    First a Mossberg 695 I rebarreled and made into a
    28GA From Hell, with a long brass 28ga case.
    Have a heavy 12ga barrel for it also.
    Second pic is 28ga FH cases.Regular 28ga works also.
    3rd is a Mauser GEHA I set up with a rifled modern
    12ga barrel from a Sav 210. I test up to 3" cases in it.
    It is originally a 12ga converted from 98 Mausers years
    ago..It used the rear bolt lug for bolt locking,
    but I added a second rear lug to the bolt.Works great.
    4th is a NEF in my 499HE case. This is where you take
    reamer and lengthen chamber on the NEF 500 S&Ws.
    With this you can use all of the variety of 500 S&W
    slugs which are in much better supply than
    the 50 cal .510" bullets at my gun shops.Ed.

    I am struck dumb with awe.

    What would one hunt with such monster firearms? Elephants? Tanks? Small planets?

    Seriously, I am envious as hell! Nice work, and keep the pics coming as you develop these things to perfection!

    Most of the worEk about 20 of us are doing-- nothing super special--
    that any of you folks can do also.. A start is to get a NEF 12ga Ultra
    slug gun with the bull barrel and reload some of our hairy loads
    for 3" plastic cases. Then ream it to 3.5" chamber and step up
    a ways with 3.5" plastic cases, and then get 3.5" brass cases
    for more power.Add weight to the gun and thicker or double pad
    and you going. Those that have pump guns can go to heavier slug
    barrels, and get good power.Rossi makes a rifled heavy barrel
    slug gun, in first picture. Ithaca makes one in 2nd picture.
    TC makes the Encore 12ga rifled slug gun in foreground in
    3rd pic with NEF behind, both with 3.5" brass cases showing.
    These and other 12ga guns with a little work, weighting,and
    reloading our beefed up loads give the
    equivalent of a 600NE.Ed

    And once you are setup with heavy barreled
    12ga guns you can load your own sabots, saving
    bucks compared to store prices.Here is a picture
    of sabots you can load own with from BPI.
    In picture is 420gr lead slug in the left two and
    a 385gr lead in right. You do up to 500gr in these.






    Once you have a gun with 3.5" chamber you can use
    both 3.5" plastic and brass cases.same for 3"
    Comparing brass cases.I tell everybody who are stepping
    up in power from 3.5 plastic, you can get 3.5" brass cases
    from Rocky Mtn Cartridge. Here you can see how heavy
    and nice they are compared to regular brass cases.
    They also make shorter 3" brass cases also.
    They fit the chamber tight and are long enough to
    get some serious thumping power.And they have a
    super strong, thick , solid head, not a weak balloon head
    like regular ones on the left in pic.Ed

    [FONT=Arial][SIZE=2][FONT=Arial][SIZE=1][FONT=Arial][SIZE=2]Tested my 499HE in a NEF.Sometimes you develop a
    cartridge just for a certain bunch of guns, those
    being all the underwhelming 500 S&W out there in
    NEFs. As well as shops always have these bullets
    in supply, much more than other big bore bullets.
    So I had a long case here that I made years ago
    as a long .510" cal, and I change the shape a little
    to fit all of the .500" cal bullets out there.
    Following loads easy on brass, I didn't have to
    full length resize the case, only top 1/4 of case that
    expanded a little. 325gr at 2600, 500gr at 2150.
    In my NEF I can get both weight bullets 300 fps faster,
    still extract very easy. With higher velocities they
    resize easy, And this case gets these great velocities
    at 50-60% of the pressure as the original case in NEF.

    I got finish 499HE reamer made by Manson.. Just run it
    in NEF 500 chamber and you got a blaster. And add
    a little weight and thick pad to the gun. I have
    a barrel ring to hold forearm along with original
    bolt, as I added weight there as well as the butt.

    Second picture a Mossberg 835 set up with a heavy rifled slug
    barrel, another gun that can handle heavy loads.Ed

    When we try to make hairy slug loads and need longer,
    heavy barrels to use the slower powders.......
    It is great when a company does it close to right.
    Some have heavy barrels but need to be longer.
    Finally an 870 with longer 1" muzzle diameter barrel. Barrel
    is heavier than most all add on pump gun rifled barrels,
    and it is 25.5" long, Something that would really get
    it on with the slower powder loads we have.
    Rifled barrel is solid mount in receiver, scoperail solid mount.

    It is the REM 870 Super Slug Gun.
    Nice long heavy barrel, and thumbhole stock for
    handling recoil better. Plastic case 3" slug loads of ours that
    gets 600gr slugs to 1800-1900 fps, work great in this
    Like the ones I load and roll crimp in second picture
    that are setting behind the little vise, and the one in the
    vise ready to be crimped...Ed

    Yes it really a great thrill to take big bores
    on a shotgun caliber platform, and get power out them
    that is like what dangerous game rifles deliver.
    And the secret is slower powders in larger amounts,
    in guns with heavy barrels, preferably longer barrels.
    And weighting the guns with thick recoil pads,
    completes the process for great shooting.
    Reloading and wildcatting is tremendous vocation, and
    doing the more powerful shotgun slug loads in plastic
    and brass cases just adds to the fun.Ed

    Here is a novel slug idea, hard plastic support ring on
    the front, and a locked base ring/seal. Metal never
    touches the bores. Work in great rifled and good in
    smooth barrels. These are steel, lead/copper would do
    great also.Could be made heavier and different points.
    If you could get plastic pieces you could cast your own
    with grooves put on the plastic and save some bucks.
    Flat point shown would do great damage to game.
    On the net- ammunitiontogo.com
    This one is about 500 gr.

    Second picture is the 499HE to use in redoing the 500S&W,
    shown on the also, in single shots, etc,for those wanting
    much more power at 40-50% lower pressures.Ed

    Well we got grizzleys, and African buffalo which
    can take a little extra to kill.

    We've experimented a lot with slower than shotgun powders
    and it really has worked out for great power increases.
    Some more testing with RE17 powder. I've used it in 2.75",
    3", 3.5" 12ga plastic, 3.5 and 3.85" brass. I like it the
    best of all, as well as the real slow powders in our
    long case with BMG primers that we started out with.
    Following tested in Savage-max pressure 35k psi.
    I took couple of our first made 3.85" long BMG based
    long cases and bushed them back to use shotgun primers
    to fire off the RE17. Works great, with 715gr jacketed slug
    and 220 gr RE17 getting 2700 . With 420 gr slug in
    BPI sabot with 250 gr RE17 getting 3200 plus.
    Following tested in NEF-max pressure 25k psi.
    Using 3.5" MRC brass, 715gr jkt and 200gr RE17, got 2500.
    420 gr in BPI sabot and 220 gr Re17, got 2900 fps.
    And we get real good velocities in plastic with half the
    basecup expansion of factory mag loads. So that solves a
    problem-of regular guns having trouble firing BMG primers.
    IE, being able to use regular firing mechanisms and
    shotgun primers, with large enough powder charges to
    get hairy velocities at mag shotgun pressures in plastic
    and higher in brass cases with heavy barrels.A good powder
    for plastic and brass loads it has worked out to.
    I see now that Lightfield Co has the Commander 3.5" Plus
    slug loads with 600gr at 1900, probably in a test barrel.
    But that is great- nice, as it seems we're being copied!!!
    WE had 600gr load in 3" plastic, that fast, 3 years ago with our
    slow powder loads, that we had lab pressure test, and it came
    in less than 15,000 psi.

    Here is picture of the cases we make from BMG brass with
    a bushings in for smaller primers. Left bmg primer, 2nd shotgun
    primer in bushing,3rd a large rifle primer in bushing.Ed

    Great work!

    Most are just shotguns that would be legal there, Like the REM above,
    like NEF Ultra Ultra slug gun. Like other with heavy barrels, The you
    reload hairy slug loads. You can probably use 12ga brass cases. I
    heard that Bruce has 12ga brass cases or is going to do some.
    And you can get different slugs like shown above and below.

    So many guys want sabot type slugs to reload their own.
    Here is an interesting combination slug available in Europe
    and they are working to get distributors/stores here.
    Any interested stores and shops contact them. We need
    many sources of saboted slugs for reloading. The sabot
    petals discards completely as slug exits muzzle and locked
    on base stays with slug, making it nose heavy so it will give
    decent accuracy in smooth bores.Will work in rifled barrels
    also. Slug is .629" diameter, comes in 570gr, 700gr, 970gr
    weights. They are selling these for reloaders only.
    It is called the US-S slug, and their site is
    europeancartridgeunlimited.com ..Ed

    The company kindly gave me few US-S slugs to test at high speeds.
    I had helped him test another slug a while back.
    He sent me some each of the US-S 570 gr, 700 gr, 970 gr.
    I tested the 570 gr so far and in 3.5" plastic case in the 1887
    smoothbore 35" barrel and in the NEF rifled 36" barrel at
    1900 fps. I got that with 130gr of RE17 with one BPGS
    seal under the sabot on the slug. The bottom of the sabot seal
    is exactly like a BPGS, so a BPGS added gives double sealing.
    Both smooth and rifled gave 3 shot 3" group each at 50 yds with
    peep sights and bad eyes. This slug does as good as advertized
    in smooth barrels, and smooth accuracy is as good as rifled.
    My smooth barrel is tight, measuring 723" at muzzle.
    These should be a great deer and hog slug. Folks need to
    ask their dealers to work to import these for them
    to have what seems a good slug to reload...

    On another note we may have found a guy who is gearing up
    to make 10 ga rifled barrels. I'll know later this winter
    If so I will put one on a bolt action and use the 4.1" long
    10GA FH case I made or get some like it from RMC..Ed
