    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

    Here is picture Stevens Revelation 350 16ga
    now a 16GA FH. It got a 385 gr to 2000,
    which is good for gun without a real heavy
    barrel. I lengthened chamber for the
    3.5" brass cases pictured that I made from
    BMG brass. Anyone doing this can have cases
    made by RMC. Gun is weighted to 11 lbs.
    Action can handle more if barrel heavier. Ed

    Here is picture of the bolt for my big gun, the 700HE.
    It is holding a 700HE long case. The caseholder extraction system
    can headspace a BMG rimless case,no belt, so you could
    put on a 12ga barrel, straighten case more, from .700 to .729"
    and have the rimless 12ga. Could straighten case for a
    .750" bore, even to 10ga(.775") with a little thinning of the
    top one inch of the case. Experimenting is interesting
    to say the least. 700 slugs in pic are 1000gr Woodleigh,
    1000gr PA, 825gr Copperhead Custom(CC), 770gr FP CC,
    1000gr HP CC, 825gr HP CC..Ed

    There is a new heavy barreled rifled slug gun out,
    the Rossi Model S12 1230S. It will handle our heavier
    loads like the NEF. And it can have chamber lengthened
    for 3.5" plastic and RMC brass 12ga cases. Ed

    The BPI sabot is tending toward small diameter.
    With a .512" slug it measures . 727"---So I run slug
    into die and reduced it .020". It is lead, swaged easy.
    Shot a BPI sabot with 385gr Great plains slug in 700HE
    great big gun pictured above. That Great plains slug
    was reduced .020". With 300gr of super fast ball
    powder blend in 3.85" case got over 4500.

    Using slugs with locked on bases and RG's hollowbase
    jacketed slug in 3.5" RMC brass cases in the 1887
    Win levergun. RG's 670 gr HB- 2500 . Brenekke KO
    435gr- 2700, Lightfield 460 gr- 2600 . Even got
    a 385gr in BPI sabot to target straight.Levergun has
    34" smooth barrel and with chamber for 3.5" long
    cases it is run as singleshot. Barrel is a tight smoothbore
    going from .726" to .722". Took out lifter and other
    stuff and put in a bottom style extractor I built that
    is operated by the lever at bottom of opening
    stroke. Then take cases out with fingers, thus able to
    handle long cases in a short action.Makes a real old timey,
    neat looking, single shot blaster. Also have testing all done
    and loads set for 12ga Encore. It is set up for 3.5" plastic
    and brass cases for strong loads. I like to sell it to someone
    who likes the style. If interested contact me.Ed

    Before I posted about testing a NEF in 10ga with
    a medium heavy barrel. The newer one is better.
    It is the one I showed the ported barrel previously.
    I did some 10ga FH testing in that newer, real
    heavy barreled, NEF 10ga, that is going to soon be an
    8GA FH, after reaming out. The internal brake set up
    on the end as shown in picture above works great.
    I stopped all of the muzzle rise and cut recoil
    Gun now is 14 lbs and has thumbhole stock.
    Top load with 3.5" plastic case, 765gr slug,
    135gr of 4227, 2200 fps, 8200 ft lbs.Ed

    28GA FH new slug.. The Lyman cast 20ga slug made to
    fit in a 20ga shotcup for 20 ga slug hunters, works perfect
    in the 28GA FH brass case. It is a hollowbases hourglass
    shaped 362 gr slug. No wadcups or wads needed, loaded
    right on powder. It is the slug you buy the molds to cast
    your own or you can buy them from guys who cast for
    sale. I use slow rifle powders in case so no air space,
    they fill to the slugs. I got 2900 with moderate case
    expansion and it hits target straight on, from a smooth
    28ga heavy barrel on 695 Mossberg bolt action.

    Other new info on primers. Some of the guns can't have the
    firing pins or hammers beefed up easy like my Enfields
    With some magnum primers with hard cups you get delayed
    ignition if hammer doesn't have perfect hit and high strength.
    One test with a small diameter case/bore that any primer will
    ignite slow powders fine with good firing pin spring would
    show delayed ignition with shotgun battery cup style 209
    CCI Mag and 209 Federal Mag primers, and when I tested them
    in cases with just the primers, they only put in a small dent
    when they fired, but WIN 209, REM 209, RWS 209(used in
    Brenekkes, Lightfields, Hastings), dented in much more when
    firing just the primer. And with the smaller bore you had fire out
    the end of the barrel, so you could compare primer strength
    visually. The REM 209 was as good or better than CCI and FED
    209 Mag Primers. The WIN and RWS was close behind. We put
    the REM in same case/gun where that we had delayed ignition
    and it fired instantly, no delay. The two mag primer brands have
    the primer insert in cup rounded a lot and little harder metal,
    and the other 3 metal cup insert is almost flat and slightly
    softer. It is easier to get a better more solid strike and dent.
    I always figured mag primers were best in our hopped
    up shotgun loads but not anymore. It took a while but I finally got
    everything around for proper test. Hopped up loads(regular also)
    we have talked about, use REM 209, where the firing pins
    and hammers can't be strengthened. Even loads with Longshot,
    Blue Dot, Steel, HS6-7, etc.
    Hope this helps.....ED

    Here is picture my NEF, soon to be, 8ga gun.
    It weighs 15 lbs. The hollow butt and hollows
    in the forearm are weighted. It has a neat recoil
    barrel ring I added so forearm stays put.
    It has internal brake on barrel that I picture
    earlier in thread with the porting holes.
    Second picture is a Lyman 520 gr slug on the right
    that we are testing . They go in regular 12ga shotcups,
    and many folks have good accuracy with them, even
    in smooth bores. They are hollowbase nose-heavy
    design. These are the ones you cast your own.
    And there are guys casting some for sale.
    You see two in wadcups on the right.
    On the left is my prototype of the Lyman
    style, of 900gr for our 8GA FH. Going to get a
    mold made. The base of it will fit the 8ga shotcup
    used in the kiln gun loads, and the front will be our
    smoothbore 8ga size, .832-835". I designed this
    as the flat ended kiln slug without a hollow
    base and heavy in the front, wasn't designed
    to give 100yd accuracy in a smoothbore. Ed

    RIP on AR forums been testing starter powders loads, with
    shotgun primers,with Blue Dot starter and HBMG main load. And
    I just tested some variety of ones myself.
    Doing some testing with starter powder, 15gr Blue Dot, with
    slower powders that fill the cases with minimum wads.
    Tested in 3.5" RMC case in NEF with shotgun primer,
    with 36" added to barrel.Remember I have extra foot of bbl.

    These 4 top loads expanded case, where I check it, just above
    thick base section to .811" from .807" resized.

    1000gr jacketed, 230gr HBMG, 1800 fps, 7200 ft lbs,
    with 1/8" card and 1/4" felt wad.

    715gr jkt, 270gr HBMG, 2200, 7600 ft lbs, 1/8" card.

    600gr Dixie, 250 gr Retumbo, 2400, 7600 ft lbs, 1/8" card.

    385gr jkt AL core, 250 gr RL25,2900, 7200 ft lbs.
    This is faster than lighter loads in NEF, using 4227 powder.

    Now the starter powder loads, which a few guys like, increase
    powder speeds so that HBMG acts like RL25. In first example,
    with 1000 gr in RMC case you couldn't use 230gr of RL25
    as that would expand RMC brass too much and stick the case.
    A few guys have found that slow powder, with starter
    powder is easiest for 1000gr and heavier loads.

    On another note, I've heard around the grapevine that if
    enough of us ask for NEF to make available a 12ga Ultra with
    a 28" rifled bull barrel that they would do it.Start calling
    folks, maybe do some good. Just tell them these new sabot
    and fullbore slug loads need more barrel to get the velocity
    out of them. 1-866-776-9292. Ed
