XAUSA, John Buhmiller was "DA Man". I have an article somewhere in my files about his work in developing what turned out to be the 460 Weatherby, and using it on a Elephant culling operation in Africa many, many years ago.

You are absolutely correct about using something other than the Enfield action for a 505. I only want to do it for the challange, might turn out to be a candidate for the scrap box. And yes, we really do not need the case capacity of the 505, however, nostalgia creeps in and makes guys like me just want a 505. I have a 450 Rigby built on a CZ550, If I ever went to Africa, this would be more than enough gun.

NITROX, I would be interested in your 505 barrel if it was not so difficult in getting it into the US. What make, twist, contour, length?
