It's old Folk Lore that Werewolves have a weakness towards silver. So in a game that involves body parts of Cthulhu, you'd expect that at least silver bullets would do extra damage to werewolves. This could also be used as a weakness with people using a moon charm. Even Wikipedia says that it should work that way! So, I'm saying, why not? You could even make silver bullets a bit more rare if you wanted to.
