I wonder how many transfers we'd have to do to actually break the system. If 20 of us got together and transferred 20 guns 8 times over the NYE weekend with each gun getting back to its original owner by (math math math... bah!) a bajillion different 8 person paths, would that tie them up for a week? A month? It's only 160 transfers, but with 80 of them having one date, and 80 having another date, untangling them could take a long time.
