Before taking any gun into the field to hunt, I give it a coat of spray furniture wax, both inside the barrel and lock mortise- which I have already sealed with stock finish--- to further water proof the wood. It only takes a few minutes, and I do it as part of my usual preparations, which include checking to see that all screws are tight, but Not TOO TIGHT, everything moves smoothly, and gets a fresh drop of oil, and that the barrel is flushed out with alcohol to remove any excess oil, or congealed oil from the breech. The inside of the lockplate gets a fine film of oil, along with all the parts, as a further rust prevention measure. I inspect the flints in the gun closely, and replace any flint I believe has seen its better days, with a new flint. The Gun, empty, is tested for sparking, so that I have no concern that the gun will fire instantly in the field the next day.
When the gun is ready, and back in its case, I then check and put together all the necessities for my hunting pouch, day pack, powder horn, etc. All this gear gets put together near the door, so I don't forget it. I also take my range box, and my range rod, to stay in the car as "back up", in case I need to make some repair in the field. I found its a lot better to have my "stuff" and tools in the car, or SUV, rather than sitting useless back at home- often hours of driving time away. :surrender: :hatsoff:
