Now that Spring is around the corner, my brother and I are planning on planting several guns and necessary ammunition. In kicking around several ideas last night, we have the following questions: 1. Since we live in a region with a high watertable, how does one best guard against water damage because of leaks in your burial tube? Grease? Total submersion of the weapon in say mineral oil? My brother suggested a plastic lined tube filled with something like mineral oil. If the ground does shift and the tube does crack, the weapon will still be encased in at least one layer. 2. What is the best way to store ammo? Vaccuum packing? Inert gas displacing the oxygen? 3. What countermeasures are effective against metal detectors? Scattering metal around burial sites? Fake/dummy spots? Metal rebar a couple of feet above tube? What about coating the burial tube? Is a coating effective, like asphalt? 4. Do you think there are any countermeasures for seismic probes?
