So I left my to-go bottles of Ammo in the car not that long ago and it got down to like 19 that night. Question was what effects would getting this cold this have on it?
at least it was only part of a to-go bottle 
Nothing will happen if it gets really cold. Alcohol dosnt freeze so you dont have to worry about that either. Its heat that you need to worry about. Keep them in a cool, dry, dark place like your closet.
