I am getting a savage hog hunter in .223 or a Howa 20" threaded hvy brl and dropping it in bell and Carlson target/competition stock. With the Howa I assume I can use the legacy sports bottom metal and drop it in with a little fitting? For the savage since the hog hunter doesn't have a floor plate I'm guessing the stock will need to be sent to and milled for CDI? I assume the dark eagle mags won't work because they are designed for factory savage factory detachable mags. Don't need anything super heavy duty although it would be an added bonus. Any ideas/experience?
