Re: Guys lets talk. POWER POWER POWER in the short action rifle

With all this discussion of 338's, I've gotta toss in a monkey wrench....how about 7saum? it will send the 180bergers at 2900 out of a 26" barrel. If you went with a 28 or 30" barrel, you could probably get darn close to 3000fps.

    Hay my thread is going again. Lots of great ideas, I love the 338 ideas. This thread was started before the introduction of bergers new 30 cal offerings. I think the only way to get more power out of the SA is to use a case with a larger diamiter than the wsm.

    After reading all the 338 WSM data people posted here I am very glad I made a 338 RCM instead.
    Results are almost identical.

    225 accubond from 22" barrel and RL-17 2750fps
    --------------------

    Still think the Lazzaroni cases offer more than the WSMs.

    I have to ask this one question before I attempt to play.....

    By "most powerful" are you referring to raw energy, raw speed, or does this badass have to be top of the line in BOTH qualifications?

    Re: Guys lets talk. POWER POWER POWER in the short action rifle

    Well if your looking for any random idea, put this to thought, with Matrix making a .277" cal 165 vld with a claimed J4 jacket that would make its design practically identical to a Berger hunting vld and matrix claims a .650 G1 bc, with that put in a 7mm wsm necked down, 40* improved case and a stiff charge of H1000 or similar should get 3200+ fps from a 26-28" barrel and could be loaded to 2.995" oal. Its bc is right there with a 7mm 180 berger and has less drag. Run the numbers with that and you may be shocked, they are easily getting 3150fps in 26" barreled 270wbys and the 7mm wsm has about a 1.5grn powder capacity over the 270wby in its standard 35* configuration. Then again if you are like me and do not like the 27 cals then id consider the same configuration in 6.5mm, but it would not be barrel friendly.
