.270 win/wsm question

[Madhouse]

Hey guys, I just picked up a Ruger American Rifle in .270 Win, then proceeded took up a couple of boxes of .270 WSM ammo (noticed when I got home).  Are these interchangeable, or completely different?  I mean, I know it's the short mag rounds, but does a rifle in .270 win accept both?

I think the cases are completely different.

Madhouse, you could trade with me some 270wsm for 270win.

Win Win situation !  <thumbsup>
