Gary,
If you are considering a .416, go with the Rigby. The Rigby operates at low pressures. My .416Rigby produces less felt recoil than my .375H&H. Its a much slower push. Whenever I take that rifle out of the safe, I get those butterflies in my stomach that only a teen gets going on their first date with a new girl.
Is there any reason why the Rugers' interest you?
Well, the Rugers are a more modern design, less expensive everything especially ammo. How much did you pay for those butterflies? That sort of thing in general...
