About William Douglas double Rifles.
William Douglas sold a bunch of actions to Cape Outfitters in the 1990's. Some of them were made by private individuals or unknowing gunsmiths into double rifles, they were shotgun actions,period. William Douglas never made a double rifle.Only shotguns. They will not continually take the pounding of the 470, or any other high pressure rifle round. They have no 3rd lock. And the Mono block is too thin for the cartridge. You may fire 10 shots, but number 11 is going to be your last.Period.Maybe you will live, probibly not. If you sell this peice of crap, get ready to be sued. They were made in Holland, barrels made in Italy, and assembled in the U.S.A. with no proofs. If there are proofs, someone else stamped them in the U.S.
Call Rigby and they will tell you the same thing, or call Ken Owen, in Tennessee.
