I keep telling myself that I need one of these like I need another armpit, and that for what I hunt, and where I hunt it, it would be slightly less useful than a rubber crutch.

Then I catch myself looking at left-handed Savage 20-ga. bolt shotguns, and wondering......

    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,   
     2 on left necked,  2 on right formed in hydro die after necking..



    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. In the 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 srtill  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 also,
    Questions, 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
