Come on, folks, use your heads. The time for hoping things will get better in 15 years was 1994.
Scouts Out! Cavalry Ho!
I’m in the camp of “Bury what doesn’t have an associated 4473, turn in the rest”.
Then, when the turn-in is done, it’s proven that “they” have irrevocably “crossed the Rubicon”, then dig the non-4473 stuff back up.
I can see the need to bury a few in order to survive the first round of confiscation. If it’s in your house and they’re serious, they will find it. You probably need to have a few to give them to keep them happy. I think you would need a quick, hard to find, stash point so you can get your good stuff hidden on short notice. I can’t help but believe they know who has what. You should also create some real plausible deniability to explain what happened to certain missing pieces. Start now to develop some type of minimal paper trail, like a for sale ad posted on some internet site etc..., an ad in a local trader paper etc... Get your story straight in your head now and visualize the “sale” scenario so you can talk about it at will with comfort. If you plan to tell them you sold it at a gun show, as a walk in, go to the gun show, walk around, get the dates and feel of the place in your head so you can refer to your visual image. Picture the guy you sold it to. Maybe some guy came to your house to buy a refrigerator from your craigslist ad. Use him as you mental picture of you “buyer”. Use this guys car as the mental image of your “buyer’s” car. Do the mental and physical work now so you don’t have to hem and haw around when you get asked direct questions on that day.
