    Here is a picture of the 12ga FH brass case that Nathan

    Vale had Bertrams make. Next to short plastic case.




    Here is a picture of our 585BB headstamp. Perfect lettering

    for our case as it came from production line,.




    I like Hogue stocks, but they aren't made for singleshots.

    We use singleshots for our 12ga FH and 585HE.

    Here is picture of a NEF we set up for 24ga FH and we adapted

    a Hogue 1300 Winchester Hogue to it. Looks a lot better, and

    handles recoil easier than factory, Butt hollow, easy to add weight,





    Here is picture of 585 case in the Lawton bolt, and the wildcat

    375s and others made from our cases, work in bolt also. Ed

    Our friend Brian from the far north went to Africa with his 24ga FH he did in
    a NEF break action and got 3 nice buffs with it. Good job.


    Our 585HE, 700HE and the great 12ga FH are now in the new COTW book
    published in Oct, now out for sale,




    We now have our target 375 HE cartridge, made by necking down our 585 HE.
    The others couldn't make enough 375s, so we started our own. It has different
    shoulder taper, length, neck length, improved over the others...Got a bunch
    guys doing it, most into the 2 mile shooting venues, We're making cases,
    testing, reamer prints at reamer guys, we are getting guys going. The 2 mile
    shoot last year really got the interest booming for 375 necked from our case,

    Here's how, size and seat 375 HE, one simple die, a 1" die, no huge dies needed
    A die we can make with resize reamer from reamer guy, a regular die body,then
    pass on to the next guy, one reamer can make whole bunch of dies for folks.

    I do primer work separate, not in the press. SO First with lock ring set, I size cases.

    When coming back out of dies with case, we notice the case still well centered,
    held straight, when it is down as far as the length of the 375 HE neck... IE
    the sides and shoulder corner still supported tight.

    So we put washer or another lock ring on, same thickness as neck length,
    below original lock ring, screw down tight tight in press,

    Dies had a 5/8 x 24 thread in top, had powder fill bushing and other stuff same thread,
    reamed out from bottom to set bullet height, with ram, case,and bullet up,

    After priming, loading in the powder charge, we carefully start(boat tail makes it easy)
    bullet in case by hand, slide up in die, into holder, raise ram to to top, bullet seated
    perfect. Die can have different thread in top as long as big enough to hold seating
    bushing of some kind , that can be made from many items.

    These target bullets held in by strong neck tension, no crimping needed, and notice
    bullet point will get no marks or dents, fast, easy, no 380-500 buck special dies.
    Bushing centering bullet on ogive is very accurate.

    OVER 900 375HE cases piled behind presses getting done. About 600 on another
    bench nearly ready. Small batches in shelves.And we will do more.

    All 375 info, prints, specs, pictures, load data, etc, is public domain, worldwide,
    for any target, hunting, etc, use..Ed

    Here is picture of one of 3 buffs our guy from Canada got in

    Africa with our 24ga FH he did on a NEF, in 2nd picture








    Here is the neck die setup, with insert stems/plugs for the top that

    are set in .020" steps to make our 375 HEs shown behind

    from our 585HE cases. 900 cases behind and 600 on

    another bench, mostly done, and 600 started elsewhere,

    We also made a hydraulic form die, 375 HE test gun, starting with

    lighter bullets, for example got 340 gr to 3700,

    Will test up to 400gr We will find top speeds and powders needed

    to get that, and have info where to get powders. Reamer prints are

    at reamer guys, all prints and info is public domain... Ed

    That is a beautiful rifle!

    I'm guessing these things try to rip your shoulder off when you fire them?

    Picture of fellows at Vestals Gunsmithing test firing 585 HE

    they built for a guy. They got 750 gr to almost 2800 from

    ultra short barrel, not a full load . A regular barrel would be

    over 2900, 14000 ft lbs with full load..





    Picture of our 375 HE cases, with little 378 WEA on left.

    Middle case is with 330 gr, right case is 400gr bullet.




    Here is picture of out 375HE testgun, in heavy t-hole stock.

    So far 340 gr to 3700 and 360gr 3600.




    Next 416 HE target case, these run through the hydro-die,

    test gun done,will complete testing soon, to confirm specs.

    When specs set, info will be sent to reamer guys

    Soon will have 408 HE with specs set up also, for guys,

    Smaller case 416s and 408s can be reamed out for

    our bigger case .Ed

    Here is picture of a brake on 12ga FH with real hot loaded
    hollowbase lead slug, brake needed more clearance
    for the expanding slug.




    Here is the before and after of 375 HE cases
    necked, 2 on left, and then formed in hydro die... Ed




    Here is pic of 416 HSM second from left we are experimenting
    with, going to see if we can make the ultimate 416 ELR case.
    Can be 3.60" to 4.00" long, a long one pictured.
    Holds over 280 gr ball powder under bullet. The
    3.6" case can hold about 250gr under bullet.. In picture,
    1st case is 416 HE, 2nd 416 HSM, 3rd 375 He, 4th 378 WEA.

    416 HSM will get 400gr to 4100 plus without needing BMG action,
    470 gr 3800 plus , it may be the ultimate target, singleshot 416..
    Case will work in fat bolt actions, with heavy enough barrel
    to have good, milder, barrel harmonics and be under 50 lbs.
    A lot of the 2 mile type shoots are adopting 50lb limit.



    Here is picture of the 416 HSM fireformed once,
    next to bmg case we make it from and as we
    improve wildcatting process next few weeks
    some specs may make small changes, now from
    base to shoulder is 3.45", case 3.97" long. Ed..





    Manson has 416 HE and 408 HE prints, as well as 375 HE
    He can also make you a resize die reamer from that info.
    We got 700 cases in 416 and one more pass if 408s wanted, ,
    Going to do lot more cases for these 2 sizes,
    PM or email. ph 989-644-5228..

    Here are final specs for 416 HE.
    Length 3.32", belt diameter ,655", base dia .635" ,
    length base to to shoulder 2.860" , 30 deg shoulder.Ed

    Guys asking about strong economical bolt gun to use for 28ga and
    410 ga and 32ga with brass cases and higher pressures than plastic cases.
    They can use a MN bolt action, here is pic of one with
    our 585 case in the action.Guys can get Magtech brass cases or have
    RMC make them....Guys can make 32ga case from 500 NE,
    410s from 9.3 x 74 brass, etc..



    Here is picture of our 416 HSM case sectioned next to original
    BMG case on the right sectioned, to show that we still have
    enough thickness in the sides to handle high pressure,
    in a case with 310 gr capacity..We are getting the wildcatting
    work set up so we can do at least hundred a month.
    We have lots of 585s, 375HEs, 416 HEs, 408 HEs.....
    And working toward getting 416 HSMs in big numbers.



    Here's comparison of 416 target cases, 1st 416 HE, have whole bunch.
    Second is model of what I'd have made on medium machine, if I could,
    the 416 HE Long. It has capacity of 230gr..
    Third is our 416 HSM which we are working on making by wildcatting bmg
    cases, And if had run long cases, make longer 375 HE necking down 416 ..




    Bryan Litz just recently shot 3 shot group at 2 miles using Paul
    Phillips heavy barreled, target rifle built by Lethal Precision in
    375 Lethal Mag(585HE necked down, very similiar to 375HE )...
    It grouped 17.5 inches tall by 22 inches wide.

    Applied Ballistics shooter Mitch Fitzpatrick just hit 3 of 5 at 3520 yards,
    weekend 10-13th at Valdina Ranch , west of San Antonio.
    Also used the 375 LM case similar to our 375 HE
    Great shooting at the 2017 World's Longest Shot Challenge. Ed

    The 12ga FH case now is in the new COTW book on
    last page in the wildcat section, I think page 324.
    They gave good credit to Rob for the idea of that case....


    The model 416 HE long case in middle, hydro formed one,

    has case capacity of 240 gr, and the 416 HSM in picture,

    on the right, we fired a case twice, capacity is 320gr.. Ed..




    More info out now; short, fat cases sticking, pockets not lasting as expected.
    Trying to get best speeds the things raising pressures are bad case
    proportions, too sharp of shoulders, too fast of powders...........
    and debth of the bullet into the powder space, as shown in the picture below..
    My 375, 416, etc testing, bullets loaded like bottom one, in longer freebore....Ed.
