I'll chime in here since we have the exact same rifle. I've never shot mine from prone, and don't plan to. However, I don't plan to hunt deer with it either. What I can tell you, from experience gained in a recent safari, in real action the recoil is just not that bad...especially when the heart is pumping and adrenaline is rushing. Of the eight animals I took, six were with the .416 Rigby and the recoil was unremarkable (though I did get a slight kiss from my scope once). You've made a good choice; the mighty .416 Rigby is an outstanding caliber for Africa!
