The dry ice CO2 for air purge is a good concept and has sound physics principle. It should make a huge difference although a nitrogen or argon purge would be even better eliminating oxygen atoms completely thereby not only eliminating organics, but also rust.
metal detectors can find buried guns. I suggest you bury your cache on a property line for deniability purposes should it come to that.

I would have to say someone would have to try it to confirm it but I think it might be possible to use lead to mask the gun. I know if they try to use ground-penetrating radar the lead would mask the objects in the bucket but I had a thought that lead would help with fooling a metal detector. Like I said someone would have to try it to see if it would be possible.
Hey, 2bear, any idea how that nitrogen or argon purge might work? Also, I thought that petroleum (a la Vaseline) would degrade the rubber gasket on a bucket lid. At least, it is supposed to have very negative effects on a certain other rubber barrier.![]()
Pumping an inert gas like nitrogen or argon into a container pushes the ambient "air" (mix of gasses including oxygen) out of the container. Get a small bottle with a section of hose from a welding supply shop, stick the hose in down to the bottom of the container, place the lid loosely on the container so it holds the hose in place. Crack the bottle's valve. After a few seconds, the air will be replaced by the inert gas. Since there is now little or no oxygen in the container, oxidation is at least hindered. This means no rust, no corrosion.
