I hunt with a friend and he uses a SBE II and there have been a couple times that we have been goose hunting in layout blinds in harsh/COLD conditions and after his first shot the gun literally freezes up wont cycle in a new shell. I've heard that if you use a light coating of certain types of oils your gun wont freeze up as bad in really cold conditions. Just wondering what are the brands and types of oils that would be recommended in these types of COLD conditions??
