The bullets cannot be fired from the same weapon because they require different sized chambers and barrels

Guess some stupid reporter out there has never heard of using a .30 / .223 sabot sleeve on a round.

More likely some stupid BATF "expert". One wouldn't necessarily expect the report to have heard of sabot rounds, but the "expert" the reporter talked to should have.

Of course it's possible this is disinformation to let the sniper think they are not onto this particular aspect, while in reality they are.
