I agree.
Lowest I would go is that 400 grainer in the pics and wouldprefer the 460 NEx over that one. If you want less recoil just reduce your powder charge. Recoil from that rifle with 80 grains of T7 FFg under a 500 grain conical isn't bad at all. Stock fit and geometry have a great deal to do with perceived recoil...the Ultra Mag stock is well designed.
