    Wonder if a PTRD with 5 ft long barrel is stable enough

    for ELR , rebarrel to 416 and use our 416 HSM, 500 gr bullet ....

    .Here is up north guy using 585 HE in a PTRD with inserts,

    Light load.....Inserts are in the shape of the 14.5mm case....





    HERE ia video, 585 Hubel Express and water jugs - slow motion

    750 gr with 155gr RE17, just a moderate load.....Ed

    20mm Vulcan is a big case that works ok, without having

    the sides made too thick...They have thinner sides

    than smaller cases guys are getting that have the sides

    made too thick and won't extract easy or work with high pressures.


    Here Barnard P Cheytac bolt that would do for our 416 HSM..Ed......

    Got guys doing various 416 HEs..

    One just built a 416 HE, just been testing it a few days..

    And using 168gr of HBMG 475 gr CEB, tested it, in good

    conditions, 2 shots at 1800 yards and was within

    a 1/4 of minute accuracy...A few shots at shorter ranges

    had same accuracy. Ed..

    More about our 416 HSM from BMG brass, and
    our 416 HE & 460 HE from our 585 HE cases
    Got reamers for 375 HE, 416 HE and 416 HSM,....

    460 HE & 460 HSM are all spec'd, got HE reamer
    soon have HSM reamer...Our HSMs have a Wea type
    radius on the shoulder..

    The fellow that set up our 416 HE in an ELR rifle
    and got 1/4 min accuracy,
    They got some game out west over 1400 yds..
    .Here is the gun they set up.

    And have got 460 HSM specs setup, the impetus for that is some
    asking about one and new great line of 458 bullets CEB now has.

    It will hold more powder than the 416 HSM and will get
    a 572 gr as fast as 416 HSM gets a 475gr.....Ed..

    The guys that did the super accurate 416 HE did another
    416 HE that has an 8" longer 42 inch K&P barrel..

    Used a Stiller action and same load with 475 gr bullet, as in
    first gun and and gained about 200 fps with good accuracy.
    3065 fps. Tested 2 groups of 3 and less than 1/2 min moa.
     
    And loads they used are not the highest speed loads
    the cartridge is capable of....Here is  print with specs for
    the 416 HE reamer chamber ....Ed....

     416 HSM  chamber..There are 3 base sizes we have,
