WW Greener Empire grade 10 that I bought with barrels in severe condition, now has a monoblock by Ellis Brown in 4140, with a pair of .475" bore barrels in Pacnor #4 contour (very close to Searcy .470) fitted. Will be chambering to my wildcat, .475 Morrison, which is a blown out .45-110 to .475. She'll be strong!
