I am getting a safe in the near future and am trying to determine where I want to put it in my house. It' s not a big one, only about 300 lbs. which isn' t a factor in where it will go. The question I have is about what is a safe humidity level to maintain. My basement is probably the best place, but tends to be a little humid. Currently it' s at about 55% and the dehumidifier runs pretty much all the time to maintail that level. Regardless if I put the safe down there I am going to purchase another dehumidifer so as to be able to keep more stuff down there. If I can maintain 55% humidity is this an acceptable level to store guns in a safe for an extended period of time? What would be the max. level you would feel comfortable storing your guns at?

Thanks.
