    .308 supersonic load to 1000 yards out of a 20 inch barrel??

    I am shooting an accurized rem-700 .308 with a 20 inch krieger barrel with a 1:10 twist. I normally shoot 168 GR HBPT's. I will shoot fed gmm, but it gets squirly out past 750 yards.

    I want to effectively shoot out to 1000 yards in some tactical competitions at my local club, but I am not sure that I can keep a bullet supersonic out past 1000 yards out of my 20 inch barrel.

    Do any of you have experience with reloading to keep a bullet supersonic in a short barrel out to 1000 yards? I was thinking of some hot loads with either 175 SMK's or Berger 155.5 commonly used by PALMA shooters.

    Any help or proposed load data you may have would be greatly appreciated.

    Thanks!

    155 Scenar (or 155.5 Berger FullBore)
    47.8 gr Varget (47.4 in Laupa cases)
    Win cases
    CCI primers
    2.943 OAL (still compressed)

    In a 24" tube will reach 1300 yards at Mach.
    In a 20" tube will reach 1200 yards at Mach.

    {Caution: very still load, right at the edge of sane pressures, start low and work up watching pressure signs.}

    178 AMAX pushed by some Varget will get you to 1000 easily as well. I get close to 2700fps with that combo from my 20" barrel.

    Oh WOW! Don't the 155s completely destabilize past 800?

    My shooting mate pushed 155 Scenars at 2830fps out of a Rem Tac with 20" barrel .... his load was 47 grains Varget, Lapua cases and Federal 210 primers. The 155 Scenars were stable and super sonic to around 1100 meters.

    Mitch's load would be great! and at 46 grains plus of Varget/AR2208 it's a compressed load so the case is full and the ES and SD comes down ....

    Great Info

    Thanks a lot! I will begin ...SLOWLY...working up to those loads. I am relieved to find that you can get 1000 YDS out of a 20" barrel.

    I just shot 1,000yds for the first time last weekend, and was nervous about the same thing. I have a 20" stock heavy barrel 1:12 twist on a Remington 700. I shot 175gr SMK with 45.0 gr Varget in Winchester cases, and chrono'd only 2514fps, and they made it just fine.

    Your 1:10 Krieger should do even better -

    The old 155 SMK (2155) and the current 155 Amax are pigs in the air, needing 3000 fps to reach 1000 yards above Mach. The new 155 Scenar, 155.5 Fullbore, 155 SMK (2156) only need only 2800 fps to reach 1000 yards above Mach.

    Go with at least a 175 gr to stay super at 1000.
    +1 Rob.. the 178 gr work about the best from what i've shot.

    The current 155 AMAX isn't THAT bad. BC of .438 when launched at 2800 it is super sonic beyond 1000. The DMR/S rifle with 16" barrel launched the factory HSM 155gr AMAX at 2800fps.
