Here is a few sites to calculate the needed desiccant per cubic in/ft/gal air volume :

Although the one says to use the left over air volume after filling the container with product, for ammo cans I'd think Id just go with the empty volume for my requirements

I keep a dehumidifier in my basement, keep it at 60% in my play area, I also keep cigars in my humidor at 70%.
