300 g. SMK Terminal Performance

I am awaiting a new barrel ( 28" 1 in 10 twist Lilja) for my 340 Weatherby. This is not the most idea launch platform for heavy, long range bullets, but it is what I have. My muzzle velocity will be low; probably 2600-2700 fps. What is the minimum upset velocity for a 300 g. SMK in animal tissue? A better question may be -what does this bullet do upon impact with animals? Does it mushroom, fragment vilolently, or something else? My other option will be a 250 g Nosler Accubond. I can probably get the Accubond velocity up to 2900+ fps. I tried to contact Berger, via email, in regards to their forthcoming .338 options, but no response. Does anyone have data on the 300 SMK in anmals? Other than it stones them like lightning.

    300 SMK, Bull at 526 yards in 2008. The 2009 Bull at 1130 yards fell in his tracks. Sorry no pics of the 09 bull or bullet.

    Jeff,
    Thanks for the info. What was your muzzle velocity? Since I will be slower than most out of the barrel I am curious what my minimum terminal velocity should be. I can calculate your terminal velocity from the 1130 yard shot if I know the conditions. By the way the 526 yard results are very encouraging.

    That picture of Broz's bullet says it all.

    There are mixed reviews on the 300 SMK. From the reports I've read, they tend to work well on large game at good velocities or maybe shoulder shots to encourage expansion. Deformation isn't always a perfect mushroom.

    If you read Kirby's opening post in this thread, you'll see that he was "less than impressed with the 300 SMK's performance on lighter game"

    Raptor LRSS progress report....

    Overall, folks seem to like them, but there are some newer bullets on the horizon that may make the SMK's obsolete, or at least way down the totem pole.

    -Mark

    I don't think thr 300 gr SMK will ever be obsolete, no matter what other bullets come out.

    Hi Bill, I am now over 2850, but the bullet pictured was at 2750. From my 338 Lapua. The 09 elk was 1130 yards and shot at about 5800 feet, 2850 MV. It was dark when I got to the bull and dressed him. Never recovered the bullet but he literally fell over backwards in his tracks. I took a WT deer at 1137 yards in Kansas probably about 1800 feet of altitude and the bullet passes through with a huge exit. DRT. I am close to 700 rounds through this rifle now, all 300 SMK's and two hunting seasons. Many antelope, deer, two elk and even some yotes, my farthest yote was 880 yards. Even the light rib cage of a yote at 880 yards made for a big exit. I have let others use this rifle to take deer and antelope at distance. Very few go more than a few steps if any.
    And I have learned to plan for the exit or loose the entire shoulder.

    Below is a video of 2008 in Wy. Two antelope at different distances. Both entrance was shoulder I still can't believe the first one ran like she did. Trust me she was running on pure adrenalin.

    Hope this helps.
    Jeff
