I sold the .270 win to a buddy of mine cheap. . Basically so he could get into hunting. I grew up with the gun.That left me with a .30-06 and a .338 win mag.
I wanted a flat shooting rifle capable out to about 375-400 yards for sheep, goat and deer. The .338 seemed to big and the .30-06 didn't have the 200-400 yard ballistics i wanted. That is where the .270wsm came in.
the funny thing is i have never shot past 350 yards. would the .30-06 or .338 worked, yes. But i wanted to give myself a xmas present 2 years ago. since than the .270 wsm has acounted for 4 deer and a dall.
Basically it is what i wanted and liked. lol
