Question about rust and older gunmetal
I have a Sako Finnbear from the late 60s and whenever I take it out hunting I often get a little surface rust on the crown and in the first inch of the barrel from the muzzle. This is the only gun of mine that rusts like that. Is there anything I can do to prevent it? Or is it just a fair weather gun? Thanks.
