I am in the market for a new rifle. I wouldlike somethingthat I can use in all of North America (elk, boar, deer, etc.). I have it narrowed it down to 30-06 vs. 270 WSM. Trajectory,range, and energyat impact seem to be close. Ammo for the 270 WSM seems to be almost twice as expensive, but given over all volume, I amnot sure if this matters. Will 270 WSM ammo be aroundfor a while. The 30-06 will. Thoughts?
