Basically, be like John Wick and bury your shit, then cover over it with concrete. If you have a basement, this can be accomplished fairly easily.
Or, if you live in FL like me (they don't build basements in this State, as a rule) this is what you can do. Make sure the containers you use are air tight and water tight. Preferably metal because it'll handle the weight better than plastic and won't rot as easily as a wood crate. If you can only use wood crates, wrap tarps around them before covering up. Collapsible metal boxes work real well. I don't know what the other Branches called them, but the Navy/Marine Corps call them cruise boxes or det boxes. Army Navy stores can have them, or can find them if you ask.
Dig about a 4 1/2 deep hole and bury those under about 3 1/2 ft of earth. After that, pour out about a 2-3 inch layer of concrete. Smooth that out somewhat so you have it relatively uniform and level. Then cover it all up with more earth, making sure it's level with the surrounding ground, maybe slightly mounded over. But it needs to look natural. I say to use concrete because it'll help seal it from dogs and other critters, but mainly military search dogs. If you don't or can't use concrete, use tarps to cover/wrap the boxes before burying them. (Helps mask the smell from the military dogs.) But you'll have to go deeper than 4 ft. Most likely, 6 ft.
If you work diligently and expediently, this can all be done in a weekend.
The military is fairly thorough in it's searches and seizures and will notice when things seem out of place. And please trust me on this: U.S. military Working Dogs do not play around when it comes to sniffing everything out. I've seen those dogs sniff out everything that emits a scent, even when it was buried under a couple feet of dirt. But they have a hard time.finding it if they're in metal, sealed containers buried under concrete and earth. You can dig it deeper than 4 1/2 ft if you want, but that's a lot of fucking work for even just a few people (and I think any deeper is really over kill), but if they're using ground penetrating radar or lidar in these resource confiscations then you're screwed, but hey, at least you tried, right?
No idea how it compares to the containers you've described, but I have seen large capped and sealed pvc pipes suggested for burial purposes. Definitely will keep things dry and safe for a good long while. And very widely available and budget friendly.

Hopefully things won't get to that point, but...
Good luck.
