    have questions please ask. Here is pic of our
    12GA FH on the right. Ed Hubel

    Here is closeup pic of Rob's 12GA FH, a Borchardt falling block
    action. It was the first gun that the 12GA FH was put in.
    Real nice. In picture is along brass 12ga case with one
    of Rob's 2000gr bore rider, solid, streamlined slugs.
    2nd picture is my Savage 210 that I added a heavy barrel
    to and did a whole bunch of testing.Ed

    Also we redid on of the 1887 Win replicas with a long
    heavy barrel. It has modern steel and heatreatment
    and an examplle load is a 435gr slug at 2700.Ed

    Good Lord, how much does each round cost? I bet that thing has the knockdown power of a Mack dumptruck.

    Don't cost much. Plastic cases we experiment with are 15 cents each, just regular shotgun components. We use wads where needed in brass and plastic.
    The brass cases we made from bmg brass cost about 6-8 bucks, but they
    can be reloaded a hundred times. Here is picture one sectioned tp show that
    there is no thinning after 35 rounds.Dixie heat treated slugs are
    75 cents. Jacketed ones buck and a half or little more.. Ed

    No- only guns that have chamber lengthened and most important with
    heavy barrels. The slower powder loads with larger amounts
    of powder have a longer taller average pressure curve and would
    split the barrels on regular shotguns. Thus the use of heavy barrel
    NEF Ultra Slug Gun, and adding a heavy barrel to my Savage.
    And a heavy barrel put on the falling block.Our longer chambers
    will fire all 12ga rounds that are shorter. Our brass case is 3.85" and 3.5",
    3", 2.75", and 2.5" 12ga will all fire in our chambers.Ed

    Here is picture of our case sectioned next to a
    thin factory brass case to show the great strength.
    And our case in pic was fired 35 times and shows
    no stretching. Ed

    First picture is NEF Ultra Slug Gun we lengthened chamber on
    to fire our long brass case, plus it will fire any shorter case.
    2nd and 3rd pics are of different slugs we've tested.Ed

    A fellow in GA is making 12ga jacketed 715gr hollowponts

    Here is a picture of RG's jacketed 715gr slugs in various
    loads.First are 2.75" and 3" factory foster slugs\ for
    comparison. 3rd is jkt HP in 3.5" plastic case, 4th in a
    3" brass RMC case. 5th in a 3.5" brass case with small
    primer, 6th in our long brass 3.85" case, big primer.

    Long case is made from bmg brass, has big primer.
    Top hairy load in long case in Savage, 2900..Ed

    Been testing the Encore with the Nef loads. Barrel breech is
    one inch same as muzzle, where the NEF is 1.200".
    It has dovetails cut out in bottom of the barrel for
    the nuts for the forearm screws. ... At the bottom of dove tail
    there is only .060" thickness. Before reaming had back one fill
    welded as it was where the taper for the forcing cone ended up
    with 3.5" chamber. I load it with 10 gr less powder than the NEF
    on all different slugs and weights. Like the BPI sabot in 3.5"
    plastic in NEF, 437 gr slug, 120gr 4227, 2400 fps, and in Encore
    110gr 4227, 2270 fps. In 3.5" RMC brass case, same sabot/slug
    in NEF 140gr 4227, 2600+ fps,Encore 130gr 4227, 2500.
    The Encore is now 12 lbs, with hollow in butt and recesses in
    forearm with lead shot.In pic you see NEF And Encore with RMC
    brass cases started in chambers. Ed

    My shoulder hurts just thinking about that round....

    I can't get to youtube at work so forgive me if this has been answered in your vids, but have you done ballistics tests and comparisons? How is accuracy over distance?

    What others are doing hopping up loads and experimenting.
    Brett in MN uses a Mossy 835 12ga smoothbore turkey gun, but
    it is backbored 10ga size all the way out to end and has 10ga size
    choke, and he uses 12ga AQ 441gr slug with locked on basewad, from
    BPI. Using top rib bead sight only he can hit a pail 5 times in a row at
    70 yds.Amazing accuracy for overbored barrel. He uses BPI X12X seal
    plastic wad, two 1/4" white felt wads, thin card then the AQ slug,
    with 65gr of Longshot getting 2200 fps. 3.5" new cases with
    roll crimp.......I asked him check it with a scope on it sometime.

    NFG from Greybeard and Shotgunworld with pump Mossy and 18.5"
    with slug barrel. He gets a 525gr Lyman over 1800 fps with
    80gr of 4759/4227 powder. Hard alloy mix Lyman and shot one through
    17" of pine. Shown in the pic below it mushroomed to .800" and only
    lost 8gr weight. It is a wasp waisted slug that is shot from a 12ga
    regular WW12 shotcup. The skirt of the slug collapsed into the underside
    of the nose. Many guys say that these are as accurate as most
    other stuff used. He used 3" plastic, PGS wad over powder and
    WW12 wadcup with slug it. He cuts wadcup petals back to length
    of the Lyman.In pic on left you see the Lymans with hollowbase up
    and the shape of it when starting out.

    Ok I am going to get Lymans to test and Longshot to test.
    Got to see if the Longshot will get further up in velocity
    than Blue Dot. Ed

    Here is picture of a 12ga hard discarding sabot you can get
    for reloading, the BPI. From Ballistic products. In picture
    is sabot with a 437gr Hornady Great Plains 50cal slug I put
    in it. Also the 410 gr and 385gr Great Plains work.
    Finally able to load your own instead of paying 3-5 bucks
    each for loaded rounds.You can use the 500 S&W bullets also
    as well as shorter 50 cal blackpowder slugs... Ed

    [​IMG]

    Info to help loading BPI sabots in plastic,ok to use plastic
    overwad over powder, but should use cardboard card and
    nitro wads above that below the BPI sabot. Sabot doesn't
    tear up and accuracy much better. Personally I use
    cards over powder and nitro wads, And with used cases
    roll crimping onto the thin edge of sabot is uneven, so with
    my used cases I set the sabot and slug to right height and
    just redo the 6 point star crimp real hard, and the middle of
    all the crimp sectors set right on the flat nose of the slug
    in the sabot. I also do the same with RG's 715gr hollowpoint
    with the crimp sectors right on the hollowpoint in used cases.
    Roll crimping holds RG's slug in ok but its taper of the ogive and
    smoothness it doesn't open crimp all the way around when
    fired. The star crimp set slug at same height so you can get
    the same amount of powder. With RMC brass these are not
    problems but with brass to get good feeding from mag rounding
    front edge of mouth helps. Sectioned picture of RMC on right
    next to our long original case to show how well it is built
    thick and strong. One of cases has 20 firings, still good..Ed

    We get asked about putting brakes on the NEF Ultra.
    There is the concept called the internal brake that works
    nearly as good as expansion brake, with less back noise.
    Rob on AR did a couple with bunch of holes in the barrel
    in the end with the last 1.5" bored out .025" where holes
    go. Also many want more velocity in NEf and I added on
    a barrel section to mine. Combining Ideas we add smooth
    9" section of bore extension, that is same as groove diameter
    and 1.5" end of that for internal brake. Eight 1/8" holes
    top and same 45 degees to each side.And we have over
    a 100 fps in velocity gain. And with card or wad behind load
    it will seal pressure going from rifled section to smooth.
    And these types of holes won't bother wads or sabots.
    My extension is a foot longer and gets 150 fps extra.
    No need for brake in mine as the gun is 17 lbs with extra bbl.
    Here is Rob's two he fixed up, and is shooting.He has
    them reamed out longer for long 3.85" case, weight added.Ed

    Here is picture of my NEF 12GA FH as it is now,
    A while back I got tired of short barrel and
    added a foot on to it. Used breech end of left over
    Savage and a sleeve. Lined up rifling and it has
    same twist and number of rifling. Hard way to do
    it. No need for rifling, or extra line up work.
    Run many loads and it adds 150 fps with VV110,
    4759, and 4227 powders. Adds about a 100 with
    Blue Dot, and HS 7.

    Next one will be done different and easier.
    Next one will be a smoothbore add on piece of
    groove diameter, 10-12 inches long, make it one
    piece, 1 or 1 1/16" threads,about 1.2" diameter.
    Threaded 1.5" long on original barrel, and into
    add on piece, and will look like a brake and you
    could put in internal brake in the end.Ed
