If you are planning on some late season hunting with your favorite gun it is time to make a few small changes before going afield.
Gun oil/grease and cold temperatures do not mix well. If you are using an autoloader, this advice is especially important. Before taking off on your cold weather hunting trip take your gun apart and spray everything, except the gas mechanism on autoloaders, with a good gun degreaser to remove all traces of oil and/or grease. Let the gun parts dry for a short time and then apply a graphite power to the moving parts. Put the gun back together and go hunting.
When you are done hunting you should again clean the gun to remove the graphite powder and other residue and then apply a good gun oil.
