It depends. Bullets can be made of silver and lead. Most bullets are made of lead because it's cheaper, while a silver bullet would be more symbolic (in the Akai and BO and Conan case). It was even proven on Myth Busters that a lead bullet is actually stronger and will do more damage than a silver bullet. Just a little bit of trivia for you!
Anyway, now for my question...
How many pages are in an average Bible? I'm not religious and I don't read the Bible, so I was just wondering...
