This probably belongs in the regular gun forum, but I am especially curious with respect to my flintlock, so...

I keep my guns in a locked case in the garage. The case is not insulated/temperature controlled in any way. However it does have "air holes."

With the temperature getting colder, are there any special storage considerations I need to take in to account due to the coldweather?

I live in Phoenix, Arizonaso we don't get as cold as you east coast guys-but it does get to below freezing at night.

Besides a thorough cleaning and coating of oil in all the usual places, is there anything else I should be thinking of?

Thanks,
