Wild Bill Hickok fired his .36 cal. 1851 Navy Colt percussion guns every morning as Practice-, before returning to his room and cleaning the guns thoroughly. Then he put a new load of powder in the guns and reloaded balls in them, to carry the guns for the rest of the day and night. Its how he stayed alive as long as he did.
I shoot the loads out of my gun at the end of each day's hunt. NO, shots do not spook game away. We proved it the one year that 7 of us fired the loads from our guns, and then were standing around a bonfire talking when the largest buck anyone of us was to see that season came walking in towards us, and crossed the meadow we were in about 50-60 yards from us- with not a loaded gun in the camp! Another smaller buck was with him. That was a damp day, and while the 2 flintlocks fired the first time the hammer dropped, the 5 percussion guns failed to fire- only the caps went off-- when they first pulled the triggers. The moisture had gotten into their powder charges in the barrels, and they could not fire them off until they cleaned the flash channels and dut priming powder down the channels in front of the nipples.
When People ask why I fire off the load at the end of each day, THAT IS WHY! As Bakeover Bill said, the cost and time involved of firing off the load, and then cleaning the barrel is next to nothing when you consider the loss of the one deer you might get a shot at the next day when the load doesn't fire.
I also learned NOT TO USE a spit patch when deer hunting, because it dried out in the barrel, and left me a rust ring right where the ball should seat. I spent more than an hour with my bore brush and patches working on removing that ring, because I didn't have a source of steel wool. I had a permanent rough spot in the barrel, there, also. That was after hunting ONE full day. I can't imagine the extent of damage that would have occurred if I left the ball and patch down there another day or two! :nono: :rotf: :surrender: :hmm: :thumbsup:
