A buddy and I were at the local gun gun shop the other day becasue he was looking for an "all around" hunting rifle. He is not a real serious hunter so he wants a "do-all" cartridge. Naturally the 30-06 comes to mind when thinking about an all around cartridge for North America. However we came across a really nice used Winchester in 300 WSM with a decent Leupold on top for a steal of a price. His concern was that the 300 WSM may not what he wants becasue it doesnt carry the notoriety/popularity the '06 and 270 carry. What do you all think about the 300 WSM's versatility and longevity? Do you think it will be the '06 of the 21st century?
