I'm a new member, so hello to all and a thankyou for any help you can give me. I just purchased an older Sako bolt action rifle, .270 caliber. This rifle was purchased new approx. 25 years ago and had not been fired by the original owner. Basically kept in a closet. Sadly, it shows some rust in a few spots on the outside of the barrel and action where the cosmoline finally failed to protect it. I'm hoping that when I clean it up, the barrel (inside) will be good and I can make it into a shooter. I recall that, at the time Sakos had an excellant reputation for accuracy and workmanship. My question, the stock has what appears to be a spanner head screw (flat with two holes) in the left side next to the action, similar to what I have seen on old Winchester Model 70's. To seperate the barreled action from the stock, does this screw have to be removed? What size spanner tool is used and where can it be purchased? To anyone with experience on this type of disassembly, who would give some advice, thankyou in advance. And I look forward to reading and posting on this site.
