Im in S. NJ were its not uncommon to get some water (floor coating) in the basement during heavy rain. I have a Winchester (Tractor Supply special) safe with a de-humidifier inside and also a dehumidifier in the basement. I dont have a hygrometer down there but it feels dry and doesnt have damp smell. Whats your experience storing guns in similar fashion? Is it safe for the guns? They get used so I will not be wrapping them in any special covering. Also I would like to move my reloading equipment to the same area. How critical is humidity to powder storage?
