Vihtavuori has published a very interesting article telling about the moisture percentage in the powders and its influence in the burn rate, pressure and velocity. They have tested the same powder with different moisture levels and recorded the difference between the two. This little study...

Powder manufacturers don't put desiccant packs inside the jugs---- is there a reason why?
I wonder how much humidity / moisture gets inside a container during the time you open to pour then close so as NOT to spill rolleyes... We need to figure out:
How much humidity at time of opening container:
Time of exposure:
How much moisture in container when new:
So many variables, It's hard to quantify... Why not just toss a couple desiccant packets directly in the container, would this be more efficient??? Kewl idea though...
I have moisture sensor but just realized it'stoo big to fit in the jug was going to monitor it for a week or so. Guess I'll have to order something smaller to test. Id assume it doesn't change much.
Moisture content will definitely affect the burn rate and characteristics of powder. There has been several articles released lately. Powder supposed to be kept around 55% humidity. If this is the route you wanna go there is humidity control packs you can buy to put in there.
