Using a silver bullet in monster mythology
Little do most people know that the silver bullet is supposed to be just as effective on vampires and other evil creatures created by evil supernatural forces. In other ancient legends, a werewolf can also be killed by wooden weapons, such as the usual wooden arrow to the chest.
At the gunshop the proprietor tells uncle Red that newly-minted silver bullet should be accurate. That is not true, not after I watched an episode of "Myth Busters". The testers fired silver bullets out of a lever action rifle. The accuracy was poor. The problem is, silver is harder than lead. It doesn't grip the barrel rifling adequately. To fire silver bullets accurately, a firearm's barrel would need different rifling, deeper lands and grooves. However, at very close range, a silver bullet would have enough accuracy to hit what it was aimed at, estimating 25 feet or so, which in the werewolf movies, is within the range usually when encountering a werewolf.
Also, in the movie Marty kills the werewolf with the silver bullet through its remaining good eye. The .44 magnum bullet should have exited the werewolf's head, making a gory mess in the process. This is not shown.
