Most of the Wilson barrels used on Rugers shot very well, though sometimes they had too-long throats--which wasn't the fault of the barrels but the reamers. The only really bad one I've encountered was on a tang-safety Ruger 77 7x57 a friend had. He could never get it to shoot, so wanted me to fool around with it. I couldn't get it to shoot either, despite a reasonable-length chamber throat, and eventually slugged the bore. The "tight" spots measured .287" in diameter, and there were some loose ones.
Dunno if I've ever owned a Green Mountain barreled No. 1, but have had Douglas and Ruger barreled No. 1's and all have shot very well, though it should be noted that Ruger started using shorter chamber throats when they started making their own barrels in the early 1990's.
