Guys, I have been storing my guns, primer, and powder in my browning safe. I was concerned about humidity so I bought a cheap little digital humidity gauge. For the past week, it is 33% and about 25% with a fireplace crankin. What is the ideal humidity and what level would you be start being concerned? Now in winter time, the whole house is dry but in the spring and summer, is when humidity goes up significantly.

Bigcountry,
For human comfort about 50-55% is good. So I'm guessing the same for firearms. As far as a good tool for testing humidity a sling psychrometer is very accurate. The higher humidity in the summer would be more detrimental to the primers and powder than the lower humidity. If you use A/C in the summer this should keep your house at an acceptable humidity level.

The lower the humidity the better.The labels on all powder,primers and ammo always say a cool dry place.

i think with all sythetic stocks lower would be better but with wooden stocks i wouldnt drive it too low. you might cause damage that way too.

Cool and dry is what I was told when I started loading .

Guys, I understand the cool and dry part. It been written on shells for better part of two decades or more. I just hear from some people that they have had their guns rust on them in safes. This is the first year I have ever stored my guns or powder in my safe and was wondering if someone knew a hard number (humidity and temp) that they meant when saying "Cool Dry place". I mean, dry is a realitive thing. People in Arizone might think, humid is 40%, but here in the east coast, 40% is a walk is dry. See what I am sayin?

Bigcountry,
You should be okay on storage of your guns. I assume you keep your home at a comfortable temp. 68-78F. Short periods of high humidity like rainy spring days shouldn't cause your guns to rust. We have about the same climate conditions where I live.
Like I said in my earlied post A/C does a good job of removing moisture from the air. If you don't use A/C you might want to invest in a dehumidifier or some type of dessicant for your safe.

The closer you can get to ZERO humidity, the better, for ammo, powder, etc. Same for guns, unless you have wooden stocks, which can shrink or swell excessively depending upon moisture content of the air. Then, it's up for grabs!

eldeguelo,
To get all the moisture out of the air you would have to store them in a vacuum.
