Normal bullets will bounce off a fully transformed Werewolf or penetrate slightly depending on the age of the Werewolf. The older they are the more invulnerable they are. Each full Moon adds to their power base. Penetrated bullets will dissolve into their base metals, and be absorbed into the bodies paranormal chemistry. It not penetrated far enough they will simply pop out as the wound rapidly heals. On the other hand silver is like Kryptonite to Werewolves, and will shoot deep into a Werewolf. Once inside the bullet will instantly dissolve, and the silver will be rapidly absorbed throughout the body. Silver is a universal purification element that is known to destroy bacteria, and in this case demonic DNA as well. There’s no way to extract the bullet. The kill is virtually instant especially if it hits the heart. It might take one minute at the most. Once the Werewolf dies it transforms back to a human despite the full Moon.
If a Werewolf is shot in it’s human form by a normal bullet then a similar healing happens with the bullet being absorbed or self-extracted from the body. Although the process is quite a bit slower. If they’re shot with a silver bullet there’s a window of about 15 minutes for them to extract the bullet before absorption of the silver poisons them to death. If the bullet hits their brain or heart then death is nearly instant. The only hope of reversing any silver in their system is to wash the wound with unholy water along with drinking large quantities as well. However the side effect will be a feeling of being sick to ones stomach along with intense sensations of evil thoughts. Luckily the effects of this will wear off within 66 hours or so.
So it’s best for Werewolves to avoid the silver bullet wielding Werewolf Hunters who relentlessly hunt them down with a vengeance. Although some simply want to protect the public, and will try to capture a Lycanthrope first with death being the last resort. We here at Mystic Investigations realize that Werewolves are still humans at heart, and strive for incapacitation, and capture rather than the easy silver bullet ridden death.
