Wouldn’t matter if it was rifled. The bullet isn’t going to touch the barrel.
Like Dookieman said, the barrel is much larger than the bullet (actually ~0.7" vs 0.5"), so all the gasses go around the bullet. Still dangerous, but I’d be more worried about firing it than getting shot at with it.
If this is a smooth bore barrel… then you’re loosing a fucking 50 cal that is not spin stabilized.
Oh god what a bad idea.
