Silica jell packs

[lead chucker]

Does any one put those silica jell packs in your stored powder to help with humidity or moisture? I have some small ones that i put in my little bottles i store caps in. Not sure if it helps or not. Seems like it couldn't hurt.

Silica packs with my primers: I LIKE that idea! :)
As for putting them in with the powder, I cannot see why not.

Just don't load them when you use the powder! :bigsmyl2:

That would work in areas that are humid.
But here in Arizona.
I would only have to have those in my powder one month out of the year.

I have read that smokeless powder contains a small amount of moisture, by design;

While I use dessicant packs in my primer cans, I do not for my ammo cans for this reason.

Johansson explains that, as manufactured, most powders contain 0.5 to 1% of water by weight. (The relative humidity is “equilibrated” at 40-50% during the manufacturing process to maintain this 0.5-1% moisture content). Importantly, Johansson notes that powder exposed to moist air for a long time will absorb water, causing it to burn at a slower rate. On the other hand, long-term storage in a very dry environment reduces powder moisture content, so the powder burns at a faster rate. In addition, Johansson found that single-base powders are MORE sensitive to relative humidity than are double-base powders (which contain nitroglycerine).

So Johansson’s advice is to keep powders tightly capped in their factory containers, and to minimize their exposure to dry or humid air.”

Confirming Johansson’s findings that storage conditions can alter burn rates, Barker observes: “I have about 10 pounds of WWII 4831 powder that has been stored in dry (about 20% RH) Colorado air for more than 60 years. It now burns about like IMR 3031.”

Im talking Black powder not smokeless. It gets pretty damp up here where i live.

My apologies, I didn't see that this was the Muzzleloader subforum;

I use them regularly in BP.

Just make sure they are dry.

Strange that manufacturers don’t see a need for desiccants in powder or primer packaging.

[LAGS]

I would think that manufactures figure that people are going to use what they buy very quickly.
So why add something that is going to let the customer Store the items for months or years .

[imashooter2]

Maybe. I think it more likely the manufacturers have engineers that tell them desiccants aren’t required.
