300 WSM or 300 Win Mag both devlier superior trajectory than the .270, .270 wsm, and .338 and pack more punch than the .270, .270 wsm, 7mm Mags, and .30-06.

I love the .30-06 more than any other cartriage, but whenthe possibilty of shooting more then 300 yards exists, my .300 WSM IS my GOTO GUN!

I'll never purchase a .338 unless I go after brown bear.
