In what circumstances will a convicted felon be found guilty of possession of a firearm for receiving and possessing a firearm at separate times?

In Wiga, 662 F.2d at 1337, we stressed that " '[c]ommon sense and logic, however, will not support a holding that the receipt of firearms at separate times must merge into one possession, thus one offense.' " (quoting United States v. Bullock, 615 F.2d at 1085-86. To do so would allow convicted felons "to establish armories where all their weapons would be kept ... [and yet] be subject to only a single count of possession, although thousands of illegal and dangerous weapons were received and stockpiled at different times." United States v. Bullock, 615 F.2d at 1086.
