Factual error: When Wolverine is being chased after the explosion of the barn, there's a Humvee chasing the motorcycle. The movie is supposed to take place in the late 70's - the Humvee started production in 1984 and started service in the late 80's.
Other mistake: When Wolverine and John Wraith arrive in New Orleans, the street is jammed with people and the casino they find Gambit in is also completely full of patrons. Yet somehow Wolverine being thrown through a wall, his loud shouting, his slicing a fire-ladder to pieces and Gambits massive shock thrust somehow draws absolutely no attention from anyone except the main characters.
Answer: That would indeed seem to be the case. Granted, it would have to be an extremely lucky shot to find one of those holes under his flesh, but, yes, it is an apparent vulnerability.
