bgavin Posted November 24, 2020 Share Posted November 24, 2020 Q: Is it worthwhile to put some sort of desiccant packet, etc into a powder tub? I have 8 pound tubs of powder that I expect will last a very long time. These are kept indoors in a modest humidity environment (inland CA). As these containers empty, there will be more air introduced over time. Link to comment Share on other sites More sharing options...
John Kloehr Posted November 24, 2020 Share Posted November 24, 2020 Assuming you are planning to use used Silica Gel packets, put them in a 250 oven for a couple hours to dry them out (regenerate them) before putting in your containers. The packets can only absorb a limited amount of moisture and if they have been sitting out for any amount of time, they have absorbed that limited amount of moisture. And yes, they do work to capture any trace humidity in a small enclosed container. I'm just answering in terms of do the packets work... I leave it to other more experienced pards to answer two other questions... Are they necessary? Are packets necessary in an average environment like inland California, and by extension, are they necessary in areas that get fog seasonally (LOL, like parts of inland California). Can they cause problems? If packets are used to keep powder dry, does it get so dry that static cling is an issue in reloading presses? (No, it will not explode from static, I have researched that quite thoroughly). But will extremely dry powder cause metering issues due to static cling?

Cliff Hanger #3720LR Posted November 24, 2020 Share Posted November 24, 2020 The powders we use are manufactured with a specific amount of moisture in the powder. If you dry it out, you may get erratic burning. Just as if you leave a container open in a high humidity environment your also get erratic burning. --------------- Open your container and pour out what you will use. Put the cap back on tight. When done reloading, pour the left over powder in to a separte container and close it up tight. Use it the next time you reload the add to it as you use it up.

Warden Callaway Posted November 24, 2020 Share Posted November 24, 2020 I've used Unique powder that was 20+ years old with no problems. Just keep a lid on it. Link to comment Share on other sites More sharing options...

Pat Riot Posted November 25, 2020 Share Posted November 25, 2020 Keep the lid on and in a moderately temp controlled area and you won’t need to worry about it. Link to comment Share on other sites More sharing options...
