"Anyone ever..." Yes. At least I started it. The wood-less and un-blued "project" is still laying up on a shelf in my shop, in fact I just got it down when my son visited yesterday. I to used the off-center liner method although for some reason I didn't think far enough ahead to do the same at the muzzle. Used a pair of 8mm Mauser take-off barrels to sleeve the mono-block. The .323 bores were close enough to the liner O.D. to make the idea inviting and most of the contouring work was already done. With temp. sights I got it shooting to minute of softball at 30yds. using the usual regulation method. Don't ask why I chose 30yds., I don't know!

I used an old Stevens action that was literally a (box) basket case. Approached it simply as a learning process and boy did I do a lot of "learning!" While the relatively weak Stevens/Savage design is not reccomended for anything not originally intended (and then only in good condition), I figured the .22LR would be safe enough. If you have LOTS of time on your hands, not terribly high expectations and a desire to have some fun with something unique, have at it!
