It rarely gets below freezing for long in Northern Missouri, until January, but Murphy's law says that now that I have said that, you can expect bone chilling weather in mid November! :shocked2: :shocked2: :rotf: :idunno:
In cold weather( below freezing),
the air gets so dry that you don't have to worry about your prime getting wet. You do have to be concerned about what lube you use. I recommend using a vegetable oil, down to 20 below zero, and then switch to a synthetic lube for even colder temperatures.
Use Alcohol before going out to remove ALL oil from the internal parts of your lock. Shoot the lock "dry"! You won't damage it simply because it is not oiled for a couple of hammer falls. The presence of oil in the lock is far more likely to cause a "hiccup" for you in the field, than oil in the barrel.
I hunted one year with several members of my local BP gun club, and a couple of the guys had trouble getting their guns to fire. When I took the locks off, it was clear that these men had not removed and cleaned the locks in Months or Years! I used a toothbrush in my tackle box to clean them out, then used alcohol to remove oil and debris. Once that was done, the locks worked just fine. :thumbsup:
