    Here is picture of a NEF breach barrel section that I threaded
    monoblock style for a .585" cal barrel, to make a NEF 585HE.
    It goes on a SB2 10-12ga alloy, super strong frame. Its
    OD is 1.210" and the barrel that screws into it will be tapered
    to match contour and it will be 1.00" at muzzle, at 32" long.
    I know these are strong enough as my 8GA FH testing shows..
    Later will do couple more with heavy barrels for 28GA FH, etc,
    as all the break action 28 gauges I've looked at have too
    thin of muzzles for our slower, powder loads.I'll have 3 of these
    that fit one SB2 frame I have here.This makes switch barrels
    big power fun.Ed.

    I fired mono-blocked NEF this week with a 585HE 32"
    barrel and the gun is weighted to 15 lbs. Thick pad.
    I have cone breech as this case is belted with thick base.
    I'll have a pic of gun later. Gun is still tight after testing.
    I can take out cases with my fingers as they don't stick.
    First 650gr, with no extractor. The HBMG, WC-860,AA8700,
    Retumbo, Magpro, RE25, W-780 loads come out of the chamber,
    with my fingers.If I tip gun up they fall out.
    Top speed with RE25 and W-780 is over 2400. Now I knew what
    to load them at because I have tested this case in 3 other guns.
    I have all the different powders and bullets tested.
    This is example of a case extracting easy,
    due to proper side taper that my 585 has....Ed

    Here is a picture of the Zabala that was a 10ga double,
    that Rob has monoblocked in heavy rifled barrels, showing
    the quarter sight rib he has made, fitted to the gun.
    He has it chambered for 12GA FH long case.
    Really beautiful work and gun.Ed

    I found odd steel block with a square cornered
    1.0" by 1.5" hole through it. It solves a big
    machining problem for me in doing a 4bore.
    And I happen to have some 1" by 1.5" steel.
    The rest of machining I can do, and I have
    the levers, hammer, trigger, etc. But the parts
    and layout are not going to copy the Wickcliff.
    To many problems with all the parts riding on the
    breachblock and the crowded stubby extractor.
    Will be my own design with hammer and
    trigger behind breachblock. An extractor similiar
    to Ruger and its shape a cross between WIN 1885
    and a Farquarson.In pic you can see drawn outline
    on the block of the shape it will have.ED

    Here is the finished NEF mono-blocked gun with
    the 585 barrel, 32" long, 1 to 22 twist.
    Chambered for my 585HE belted case.
    I used a SB2 10ga action which is same as the 12ga
    Ultra actions.I cut it off to make a 4" long monoblock.
    and threaded it 1 inch by 14tpi. I'm going to do extra
    ones 28GA FH,others.. My 585 is best 585,as the info will
    show. I have a 45-70 extractor coming to rework for it.
    I am firing first bunchs of test loads without
    an extractor, and loads with 650 gr bullets at 2450 and
    750 gr bullets at 2250 didn't need the extractor. They
    come out with my fingers. Over 8000 ft lbs.I got thumbhole
    stock now, because those with higher velocities of 2-400fps more,
    were harder to hold on to grip. Trigger guard banged the fingers.
    And higher velocity cases come out with a pry from my thumbnail.
    Here is picture of rear of gun and the fixins(bullets/cases).
    You see a fired case in the chamber, and I have cone breach
    setup so that case is in same relationship to chamber as it
    is in my three 585HE bolt guns. And is why I can get cases
    out with my fingers.OR tip gun up. The hairier loads of
    650 at 2650, 750 at 2450 is 10,000 ft lbs. Ed

    Here's pic of my to be 4bore falling block with
    the block to be the breech setting in the hole.
    Breach needs trough on the top yet, but now
    it is done for exact width and height and the
    bottom recess and link hookup is done, since
    the picture was taken..Ed

    The falling block is coming along. I'm not copying my
    first models that were a scale up of the Wickcliff.
    Complete new design, mainly in shape and type of stock
    used, the bridge and reciever setup, and trigger/hammer
    behind the block. Block will have no curved outside
    shapes, front to back. Pics soon with the stock......

    Used wadcutter style 8ga slug made by cutting off part
    of a long nosed one in picture, in my 8ga with RE-17
    powder.. Over 2300 fps. Slug is a zinc slug from kiln
    gun factory load. With nose cut back and hollow I put
    in the base it was 800 gr. It had a .20" wadcutter nose
    on it.Good tribute to Elmer. The other ones in picture,
    just with nose cut off and solid base and is 870 gr.Ed

    Another couple months maybe 4 bore/ga will fire.Just have a
    chunk of shaft on front to simulate barrel to
    get a stock fit. Got to profile barrel, thread barrel,
    fit in hammer,trigger, couple bottom bolts into action,
    design and mount extractor.. some springs, firing pin, etc.
    May change/lengthen fulcrum on lever so it doesn't have to
    move so far. Lever is held closed by little feramic magnet
    in grip. Checking on different shapes for lever. When breach is
    lowered the lever stays open due to weight of breach
    block. Block moves smooth, no rattling around.
    Guys-,I need some Vulcan 50cal V-50 thumbhole laminated stocks.
    If there are any used extra ones around let me know.
    This way of doing a FB in one piece thumbhole stock will work
    for 12GA FH with an action about a 1/4" narrower.ED

    Here is picture of 4bore/ga action with lever open and
    breach down.You see bottom of breach block.The action
    and barrel will be held in stock with 2 bolts into bottom
    of action one bolt in barrel ahead of action and a recoil
    barrel ring in front end of stock. Didn't have to add
    any recoil lugs, as the wide back of the action is
    the recoil lug. This is now called the Hubel Falling
    Block Action. Second picture is of the 4bore cases
    and 2000gr slugs, with 20mm case I make 4bore/ga cases
    from and the 30-06 for comparison.Ed

    4 bore from 20mm cases! Suddenly my 12 gauge seems so inadequate
