Use alcohol instead of grease on your patches in cold weather. For as little shooting as most hunters do in cold weather, alcohol will work just fine.
You can mix the rubbing alcohol 50/50 with olive oil, cooking oil, or ballistol, of you think you need to lube the barrel. The oil will remain behind in the patch after the alcohol evaporates. Take a small bottle ( 2 oz. no more) with you to both clean the barrel, and wet your patches. You might check out Dutch Schoultz's Black Powder Accuracy System, where he described how to make and use his dry lube system. Its the best $15.00 you will spend on an education.
