I do not see how you can blame William Douglass for faults of rifles made up on surplus actions by people who who have no idea how to make a double rifle!

Cape Outfitters imported William Douglass rifles into the US from England ,They were built in England and London Proofed.

WD made shotguns and double rifles 470NE & 500NE

The 470 is a LOW pressure round

The WD has Purdey style hidden third bite

Mono Block is NOT to thin, The WD has passed rigorous proof testing in London, My WD has over 250 rounds thru it with no problems, I know of others 2 in Australia, 1 in US , 1 in South Africa with no problems

The action was CNC machined in Holland, Barrels from Germany, The WD was built and regulated in England

The William Douglass is sound quality working rifle.

I would presume you have never owned a WD let alone ANY double and you seem to be pushing the Mexican Rigby's . Please do a bit more research before going off half cocked!
