This sort of retrofit project is practical or impractical, depending on whether or not you do your own work. Because I can do so, I often re-purpose barrels as described. When I was actively gunsmithing, I always had some customers of limited means. For these guys, I would try to stretch that gunsmithing dollar by just charging a relatively modest hourly rate and utilizing take-off barrels. This allowed them to enjoy their hobby and afforded me the opportunity to do some problem solving. For myself, I have shelves full of barrels and often swap them around, just because I can. So it is that I have Savage barrels on Rugers, Sako barrels on Winchesters, Winchester barrels on Mausers, Mauser barrels on Enfields. Often, they work out nearly as well as I imagined they might! WH
