RE: which 300?
all your going to get here is opinions. some people have different ways of thinking. if its possible try before you buy. i have both the .300 winmag and ultra mag and i can tell the difference in recoil. i did add the limb saver kick pad to the butt of my stock on the ultra mag and the recoil doesnt bother me at all.i had the 300 wsm for about 3 months before i traded it in on a .308. i didn't like the wsm at all. good luck.
