Recently completed a test with 1 x "Gun Dry" pack fitted at the bottom of my safe (10 Gun) and found that the pack only reduced the moisture to 60% Relative Humidity. The pack could not reduce it below 60% Relative Humidity.
At the start of the test the pack's weight was 128g and at the end of the test it was 248g. this indicates that there is definitely something happening.
The test was conducted from 15-8-2006 to 11-9-2006
Question is now.... is this 60% RH (DRY) enough to prevent rust from forming on the rifles inside?
I am planning to do another test fitting a 20 Watt light bulb inside the safe ?
Any comments is welcome... :dunno
