Todd. The part about bullet selection is off base as the 270 and 270 WSM use the same bullets.
Yeah, if you reload they do. But the guy specifically stated that he did not.
If you don't reload then you are dependent apon the finished cartridges that the stores keep in stock. When I test fired the guns my buddy loaned me to try I drove to two sporting goods stores and the local wally world to buy some ammo. Wally world had only one type 270WSM cartridge and the two Sporting goods stores had two types. Compare that 5 different types of ammo for the standard 270 at wally world and 7 or 8 different types at the other stores.
