I have an excellent condition Ruger 1B originally in 7 mm Rem Mag that I had foolishly rechambered to 7 mm STW. Before I contacct Ruger, has anyone ever had a #1 rebarreled by Ruger and the approx. cost? Want to gift this rifle to my Son for his first elk rifle. Do you think there would be any interest in selling this rifle as is to include dies, cases etc?
