When I bought my cabin I inherited a sako riihimaki in .222 from the previous owner of the place. I thought it was a great score but I never really paid much attention. It just hung over the mantle where he left it. Over the summer I tried to shoot it and almost blew my face off. The guy drilled his own scope mounts and left holes behind the bolt and just in front of the action. Gas and unburied powder seap out. Of coarse he never warned me. I was thinking to save the riffle converting it to .223 since I would have to buy a new barrel anyway. Does anyone have any experience or know how to do this?
