Burying Guns/ Gear...
What's the best way to go about doing this? And what firearm(s) should I be looking to bury?
I've been doing some reading, and I understand I realistically do not need a Pelican case to do this. I understand a PVC pipe that is sealed is sufficient.
I understand that I need to grease the guns to prevent rust and bury the container below the freezing line.
I understand that I should be keeping some kind of manual with the gun, a basic cleaning kit, lubricant, enough ammunition and even some common spare parts if need be.
Gear wise, I can figure out.

What I'm struggling with right now is finding what gun i'd like to bury. I need something where ammunition is realistically easy to find, the gun needs to be reliable, however It also needs to be of a reasonable price.
I likely won't be burying a BCM AR down there.

Thanks!
