  • 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.
      Using a K&P 34" barrel on a BAT action.....Ed

      • 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....
