    In the email I received it says that this bullet is an awesome balance between a match rifle bullet and a hunting bullet.

    So, would you hunt with it?

    A load that worked well for me:

    Rifle: 16″ 1:7 twist medium contour barrel AR-15, 5.56x45mm NATO chamber

    Load: (work up, be safe, use at own risk, etc.)
    LC 09 brass
    CCI No. 41 primer
    23.8 gr Ramshot TAC
    2.255″ COAL
    RMR 75 gr 3GH (LOT 2)
    Avg Vel. 2,610 fps (10 shots)
    32 fps Extreme Spread
    8 shot group 0.33 MOA (actual MOA, not iphy)

    I might try 23.7 and 23.9 gr of TAC as I just stumbled on to 23.8 gr of TAC.

    I have no idea what the terminal ballistic performance is so I won’t speak to hunting suitability.

    these bullets are great.. ..
    Just starting load development for the .224 75gr 3gh…
    I have shot 2 velocity tests that grouped all shots with in 1.5moa…
    20 rounds total… 10 rounds each test… each round with a different powder charge..
    for me getting a 1.5moa group on a velocity test is awsome
    My velocity tests usually look like they were put on paper by a shotgun…

    I consider myself to be a mediocre to fair shot…
    rifle is a Savage Axis with a Shaw 26″ magnum barrel 1:8 twist 223 Wylde chamber …(cheap)….
    it wears a Leupold® side focus VX®-Freedom® 6-18x40mm scope…

    Velocities are faster then expected from 2882 fps – 3053 fps at the muzzle…

    Has anyone tested the terminal performance (expansion and retained weight) of these bullets?

    I guess it would depend on the powder and differences in the charges as to whether it should be shooting a 1.5″ moa group. You could have started right on a sweet spot node and only varied the load plus and minus by a little.

    As far as terminal performance, I too would be interested.
