Recoil: .338-06 is like a .30-06 with 180's or heavier, depending on your setup. I had a mauser in a heavy stock, and with RL-15 under 210 TSX's, it recoiled noticeably less than my 700 Whelen shooting 250's.
Skookum: Having a Rigby in your stable means that at least 38.334% of the Campfire will bow down to you regularly. There's no contest on this one. And yes, it will take elk & moose without fuss: light TSX's driven fast, or 175 Partitions loafing along, it remains as competent & capable as ever. The Rigby/7-Mauser is the cartridge that delivers the punchline, "No, son - let's walk down the hill, & f*ck all the cows."
