    Just thinking about a new rifle and thought I'd consider a 338-308.

    I'd only be interested in using the 300 grain Sierra MatchKing.

    Any info would be appreciated and any speculation at velocity with the 300 from the 308 Win case.

    Dave,

    I'll guess if you use a long action, and seat bullets out a ways, 2000-2100 fps might be doable.

    I have thought about the same thing. Or maybe a 338-06 with the 300grMK in mind. I've guesstimated the 338-06 could move the 300grMK around 2200fps from a 24-26" pipe.

    Not impressive velocities, but considering the bullet mass and outstanding BC, it should carry plenty of power to 1000 yards.

    I would be very interested in your results if you do this.

    Dave I thought about doing the same thing. Did find this little bit of info: 24" barrel Hornady 200gr 2500-2800fps,using 44.5-46.0grs Accurate 2015. Hopes this helps. Why not just build a 358 Winchester, it uses the same case basically (a necked up 308). A bit over 2100fps with a 250gr from 22" also 300grsp with 43grs. IMR4895 around 2200fps from 24".
