Humidity control

[mosh338]

Has anyone used humidity sachets to control the humidity in a powder container. I’m considering emptying 3-4 1lbs containers into a larger container and putting a humidity control sachet in the large container. Do you think this will work?

I have never mixed my powder. My first question would be are they from the same lot?

I don't know about sachets but I've been using these :

Yes from the same lot but trying to keep the humidity constant. I find that my speed decreases the longer the longer the powder is exposed to the air. I figured that if I have 3-4 tins that are at a similar humidity I’ll have similar velocities.

Do you just put the pack in the powder container?

I have a big one hence the reason for mixing the powders in a bigger container. We don’t get 8 pounders in South Africa only 1 pound tins

I don’t have any experience doing these but there have been a couple of recent threads about it.

How does humidity affect powder? A new experiment

The humidity of your powder can have an impact on your load's performance and consistency. But there's little in the way of actual public data about it. I wanted to collect the highest quality data I could, so I sent 120 rounds downrange to measure just that. I tested H4350 at five different...

Effect of humidity on powder during reloading?

OK .How much does humidity play in the effectiveness off powder ie. say you left it in the scale for a few days before reloading again in say a high 75% or more humidity area. vs say in winter when the humidity is relatively low? now this is more than likely a non issue, but started thinking. Stan

Here's more about the issue of the effects of humidity on your powder:

Humidity Changes Can Alter Powder Burn Rates and Performance « Daily Bulletin

The leaves are falling, and that means the rainy season will soon begin in many areas of the country. With rain comes increased moisture in the air, i.e. increased humidity. And that, in turn, can affect how your powders perform by altering their burn rates.
