Wildcat 12GA From Hell.--

hubel458hubel458 Member Posts: 427 ✭✭✭
I just got a super shotgun done,that shoots the real
fast sabots I mentioned in the sabot thread below..
We used a Savage 210 bolt action with heavy barrel and
stock.Brass cases are real long and we made them by putting
12ga size rims on BMG brass and straightening cases.Here is
picture of our case next to regular 12ga plastic.And our
chamber will also fire thw regular shells.Ed

    I've fired Ed's rifle, and it would be ideal if the Amish in our area decide to revolt [}:)] It also would work for taking down a whole herd of cats deer with one shot [:D]

    Of course if you want to be technical, you don't need anything bigger than a 30-30 for anything this side of Africa dangerious game

    zipperzap--It is just well balanced and points nice.
    And the weight really makes it nice to shoot.
    Here is picture of mine built on the savage 210
    bolt action.Ed.

    Let's just say you won't be wondering if it went off when you pulled the trigger. If you know HOW to shoot a boomer, Ed's rifle isn't bad at all (if you don't know how to shoot a boomer, it'll teach you real fast, hang on tight [}:)] )

    I fired it half a dozen times one afternoon, and it just slightly rocked my 185lb body. Only about 6" of muzzle rise and no brusing.

    No ports, no brake, just a single shot bolt action with a good pad, enough weight and properly balanced (barrel heavy)

    Bob is right-it kicks no harder than a 10 lb Lott.
    Here is picture of the case we fired 36 times,
    sectioned to show there is no stretching or thinning.
    Can't even measure any thinning with calipers.Ed.

    What kind of chamber pressure are you getting. At one time I wanted to try the same thing, but using a brass case about the same diameter as the .20 Ga hull and about 2" longer. Mine would have been a bottle neck due to the fact we would have used the .45 caliber projectile. I just wanted to do it to see if it was possible. I was a lot younger then and Grandad talked some common sence into me though. I think his speech contained some swear words and a comparison of my common sence level and the outhouse. I think I will stick to wild catting the .450 Marlin round.

    oneshot--In my Savage I hold to 30,000 psi. Other two
    guys with big Borchardt falling blocks can go
    70,000. Cases will take pressures for many reloads,
    as the following pic shows of one sectioned that I
    fired 36 times.No sign of thinning at all. Ed.

    Tested a 870 gr hardened cast bullet that Greg Addington
    makes.Got it to 2300fps at moderate pressures.Lightened it
    with hollowpoint and got it to 2500 plus with no leading.
    That will make Greg happy as no one else can test them that fast.
    Here is picture of 3 with one in case. It is seated out so
    to get max capacity. It is real hard. Good for big game.Ed

    We get asked about longrange bullets.In picture is a
    pointed brass bullet that will shoot flatter than
    regular shotgun stuff, because of our high velocities.
    Good for vicious p-dogs I guess.... Ed.

    We tested a Barnes 3/4 oz sabot at high speed.....
    All 500 S&W bullets will work in same sabot that
    Federal put the Barnes in.Also lighter 505 slugs.
    And real neat, the front section of BMG surplus
    bore rider bullets. Buy them by the bushel.
    Cut off the .510 diameter back and leaves front
    1.5 in long of .500 diameter. Fit sabot cup perfect.
    It is second in picture.Ed

    Shot a 610 grain hollowpoint Dixie hard
    slug into 6 gallon sealed pail of water.
    Going 2800 fps, and real big hollowpoint.
    First pic is pail with crimped on top.
    Pail full and has filler spout capped.
    Second pic,impact with water atomising,
    and pail blowing apart.In the next small
    fraction of a second is third after impact
    with shelf cleared, the hyrostatic pressure
    down, has bent top of steel frame shelf.
    Same blast put jug pieces all over.
    Got to get a 15 gallon one. Behind
    you see my wood bundle backstop...Ed

    Impressive to say the least Ed [:0].
    That's really a well thought out design you have, and the 50 BMG bullets in sabots is a great "plinking" round [:D]!

    I'm 51, 5'8, 185lb. Ed's rifle pushed me around a little, but not real bad considering the power it has. Ed reported thet the barrel only came up about 6" when I fired it offhand.
    Recoil level is in the 100-110lb range, which is about what you normaly find when your shooting a true "big bore" rifle (Medium bores like the 416 Rigby runs in the mid 60's).

    I picked up a 12ga NEF Ultra Slug gun.24 inch shorty barrel.
    Added weight and thumbhole stock.
    Gun weighted to 15 lbs so
    far. I got 600gr hard slug to
    1650-1700 so far, and shoots easy.
    Got 1 1/2 inch thick pad.Working up different
    loads.Should get over 2000.
    Cases eject easy,no resizing needed
    on bottom half of case,action opens easy,
    no evidence of binding.Started case 3.2 inch,
    settled on case length of 3.15-- Chamber being
    full size max 12ga size expands top half of case
    more than my minimum chamber in Savage does,
    so little more effort needed to size.Our case, though many times stronger than regular
    12ga cases is thinner at mouth, so that is
    why I used tight chamber on Savage.Still
    can't get used to mickey mouse short barrel.
    Anyone know of a genius who could
    make long alloy barrel with pivot mounted?
    Cases can be 3 inches on up to
    our length, and work.Ed

    We got 600 gr slug to 2000 fps in NEF.Used ball
    powder load. Case length of maximum 3.07 works.
    Can use our case shorter, but load developement harder.
    Anyone using our style case should also put in adapter
    for shotgun primer. Save a lot of work
    beefing up hammer speed and strength.Ed

    Being some guns need to much work
    to fire bmg primers, it easier to
    do the following with adapter bushings.
    Here is picture of cases for primer
    comparisons.1st is regular bmg
    primer. 2nd is adapted to a shotgun primer.
    3rd is adapted to large rifle primer.
    Of the 2 adaptations, large rifle is
    easier to do, just ream out pocket, thread in adapter, but adapting shotgun primer
    you have to deepen the original primer
    pocket a little, then thread and screw in
    a bushing.These two primers give about
    100 fps less than bmg primer.Ed.

    Temblor- That's correct. And we got a 730 hardened cast
    to 2900 using 280gr of Win W-760 ball
    powder in Savage today. Got 730gr over 2800 with 300 gr of
    RL-22 yesterday. And hardened Dixie slugs at 70 cents each are
    a neat deal. Ed

    That's alot of powder Ed!!
    Do you think the Dixie slugs would hold together on big game like Cape Buffalo, etc ?? That's pretty cheap shooting for such a big round.
    Keep us posted -- Interesting stuff.......[^]
