    My thinking is along the lines of a 260rem, 7mm-08, or 308win.

    Those cartridges will probably preform the best in a shorter (18"-20") barrel.

    good enough for 600 yards. I shoot a 7wsm and I'm getting almost 2900 fps out of a 17.5 inch pistol barrel with a 168 smk and 4831sc. do some reading inthe specialty pistol section... my buddy is planning a 300wsm pistol with a 18 inch barrel

    +1 The 260 and the 7/08 will have better ballistics in a 20" because of bullet weight and
    BC.
