[spoiler]That was a joke, and I apologize for not making that obvious. But for real, .5mm is not the same as 5mm. You have your calibers listed wrong and to anyone who knows weaponry, that's an IMMENSELY SMALL bullet. That's close to a BB actually. If you take away the . before every one aside from the .357 magnum, you'd have far more powerful stuff. The concepts are great, the listing for calibers just needs to be tweaked. I'd be very willing to help you out as well.[/spoiler]
