    Here's another example for your friend. 55 grain BlitzKings fired from a Krieger barreled AR-15 with a 1:7.7" twist.

    All that is necessary for trolls to flourish, is for good men to do nothing.

    Absolutely; every barrel is a law unto itself. That being said, the Noveske N4 barrels are some of the most consistently accurate chrome lined, NATO chambered AR-15 barrels (of the same weight as government profile barrels) that are currently being produced. I personally own two of them (a 14.5" and a 16") and have plans for a third.

    I’ve conducted formal accuracy testing on my two different Noveske N4 barrels and their accuracy performance has been nearly identical. Both barrels were free-floated. The same match-grade, hand-loaded ammunition was used for each barrel and the testing was performed under as close to the same conditions as was reasonably possible.


    Noveske 16" N4








    I performed an accuracy evaluation of my Noveske 16” N4 Light Recce upper following my usual protocol. Testing was performed from a distance of 100 yards. Firing was conducted from a concrete bench with the free-float handguard resting in a Sinclair Bench Rest. The rear stock of the rifle rested in a Protektor bunny-ear bag. Wind conditions were monitored using a Wind Probe. A Leupold VARI-X III with a mirage shade, set at 25X magnification and adjusted to be parallax free at 100 yards was used for sighting.

























    Using hand-loaded, match grade ammunition I fired three, 10-shot groups in a row. The extreme spreads of those groups measured:

    1.29”
    1.18”
    1.31”

    for a 10-shot average extreme spread of 1.26”. I over-layed those three groups on each other using RSI Shooting Lab to form a 30-shot composite group. The mean radius for the composite group was 0.37”.




    Noveske 14.5” N4





    The 14.5” N4 barrel was tested in the same manner as described above. Three 10-shot groups fired in a row from 100 yards using match grade hand-loads had extreme spreads of:

    1.029”
    1.360”
    1.275”

    for a 10-shot group average of 1.22”. As above, I over-layed the three 10-shot groups on each other using RSI Shooting Lab to form a 30-shot composite group. The mean radius for that composite group was 0.37”.

    both of my 14.5 & 16" N4's, average around an inch at 100m using a varity of ammo.

    Can you be more specific? What's your experience with commonly available 55 grain ammo?
