If I was going to get a .270 it would be a .270 Winchester. I have a buddy with a .270wsm and he will tell you it's not the easiest thing to even find ammo for. If it's hard to find ammo for it right now while they are popular how is it going to be in 5 years? You can go to any Wal-Mart that sells ammo or even most other places that sell ammo and most all of them sell .270 Winchester ammo but not many have .270wsm instock.
