Dude, I don't know how to put this. I'll try. Quit shooting soft loads in your 416 Rigby and get to some real recoil. The more full loads you shoot with the 416, the more you'll be able to shoot the 470. Light loads should be used only after you've been acclimated to full loads and they should be used mainly for quick sight acquisition(snap shooting) and to get that manual of arms into your muscle memory. In the scheme of things, the 470 don't kick that much, try a 577 off the bench and the 470 will feel like a 375.
