Well, I don't know how well equiped you are, but here is a possibility. I read on one forum that you can fit a Ruger 22/77 barrel to a Savage receiver. It requires moving the shoulder on the barrel back. Apparently on his receiver, the Savage barrel shank was longer than the shank on the Ruger 77/22.
The hardest part was getting the Savage barrel out of the receiver. A very tight fit.
His finished project looked very nice. A fluted Stainless Steel barrel on a blued receiver.
Just a thought.
