I've always had a 30-06 and didn't see a use in me having a 7RM or .300 WM, but several of the men I know who have only one rifle (and fit the proverb with regards to caution with such a man) swear by it and their success afield bears witness to their well placed faith in it.

A 7mm RM was my only bolt action big game rifle for 20+ years. Bought it because my mentor recommended it and ballistics suggested it took a 200g bullet (with significant additional recoil) to exceed the 7mm RM/160g combo.
Finally scratched the itch and got a .300 WM. I shoot 180g bullets in it and don't see much difference.
