  • 300 AAC Blackout / 300 Whisper Bullet Options

    Sierra has announced a new 308 flat-based bullet, 125 OTM MatchKing, that is intended for the use with the 300 AAC Blackout. Remington has added this bullet to their factory load ammunition under the Remington Premier Match product line.

    G1 Ballistic Coefficients are as follows

    .310 < 1600 fps
    .330 - 1600 to 2000 fps
    .338 - 2000 to 2650 fps
    .349 - > 2650 fps

    Other options from Sierra include

    110 grain FMJ Pro Hunter
    110 grain HP Varminter
    110 grain RN Pro Hunter
    125 grain SPT Pro Hunter
    135 grain HPBT Match King

    For those looking beyond Sierra

    Berger offers a number of 308 caliber bullets that would be ideal for the 300 AAC Black and 300 Whisper including

    110 grain FBHP
    115 grain FBHP
    125 grain FBHP
    135 grain FBHP
    150 grain FBHP

    Would be interesting to try a Berger 155 grain Hybrid as well with a .483 G1 BC

    In addition, Berger has their new 308 Hybrid offerings including a 185, 200, 215 and 230 grain weights. The 215 or 230 Hybrid may make for an interesting subsonic round.

    Speer has a 125 grain Speer TNT that does very well accuracy wise.

    Taking a lesson from Palma and FTR competition, give the Lapua Scenar 155 grain a look.

    Would the 240 grain Sierra work with for subsonic use or would it encroach on the case capacity?

      I don't think reducing the case capacity would be the issue for subsonic. Only thing to see is how long a Sierra 240 MK is and more specifically how long the ogive is.
