I have a Ruger RS wood blued gun in 338 Win Mag. Thinking of reboring to 358 Norma. Should be plenty of barrel with the mag contour. I have a Whelen so thought I would make the reloading process simpler with 358 bullets for both. Anyway tell me about the 358 Norma I think it is a really cool chambering. Also can one buy a new African stock with the crossbolts and forend tip and will my Ruger RS be basically a drop in?
