    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....

    Away for a time, sickness..
    Here is print with chamber reamer specs for the
    416 HSM chamber..There are 3 base sizes we have,
    depending on actions used. Got reamers for all 3..
    Got cases for all of them..
    Our cases are public domain, so that is why I post
    info and specs. To help guys do their own setups.
    Manson makes reamers I use,,, Ed.
