I have been seeing excellent reviews on the Ruger American rifle. I have my eye on a 270 at my local Wall Mart. I am wondering if anyone here has compared them to the old reliable Win Mod 70. American Rifle has similar 3 Lug 70 degree throw bolt. Did Ruger copy old win 70 action here? Has any one tinkered with one, are barrels threaded on? Could a guy build off this action a better rifle? They are only around 300.00 new and complete! If this action could be trued and built off of ,it might be a bargain. I am only a hobbyist gunsmith, so I am asking you pros out there! Thanks ahead,
