I bought an herb grinder and it's the best smoking related investment I've ever purchased. The bullet would grind it up way too finely. I don't know about the pepper grinder. I just say get an actual grinder. You wont be disappointed. Well, unless you buy a crappy one I guess. I don't think I've ever seen one that didn't do a good job at grinding herbs though.
