I am thinking of doing Dennis' cosmo dip, vacuum sealing then putting a diaper in the bottom of the PVC tube, under the vacuum sealed bag to collect any seeping moisture. Burying it vertically next to a fence post using post hole diggers or an auger? Tape a hacksaw blade out side, and mounting a strap on top of the cylinder to help pull it out. I may do it with a Mosin to see how it would do?
