Sir Jerry, Always and forever the truth about the .458 Winchester Magnum must be revealed ! BTW, Whatever happened to the Original Sharps .45-110 Buffalo Rifle you were looking at ? You never started a thread on the BPCR forum about that. Did you pass on it or is it at home on the range with you ?
When I get the mould for the .450"-diameter (-.000"/+.002") slick (550 grains in WW) it will be interesting to compare notes on your Hellbender load for the .45-110 to see if it can be imitated with the .458 WM-BPCR.
