My first thought is Trijicon, or Nightforce.
I have not had problems with my Trijicon's, or VX 6's on 375's. or 404 Jeffery, but the Rigby is a another level.
The Rigby is where my recoil tolerance ends. YMMV
I mounted a Trijicon 1-4 on my bud's M-70 .416 Rem. It works great and is a tough scope. He trusts it and so do I.
He took a 43" buff in RSA couple years ago. 400 gr. SAF at 2,375 fps. The Trijicon allowed him to shoot the buff a couple more times before he could get away. Triangle reticle is good for fast offhand shots.
