Guys there is no sexual connotation to my question. But after handling some of the VC doubles it got me thinking about 500 or even a 577NE. However I have seen in my research that the 416 Rigby (currant double rifle (for those that say you should have a rimed case go screw yourself)) will out penetrate any of the 500's. But saying that the 500's hit with a hell of a lot more energy. I have seen that the 416 bullets have a better SD but how much difference does it make. Now I can shoot the 416 well and feel I'd be able to shoot the 500's well too. so it boils down to impact energy or penetration. What will be more effective for a nice quick death?? Thanks as always Norfolk Shooter out.
