I'm talking about ammo that you've actually used.

I tried making a dart earlier, but kinda gave up since I couldn't find any plans for ones that worked with a 40mm barrel.

I've been trying to figure out what ammo most people use if they want to get distance and so far it's been either golf balls or darts. But is there any other ammo that can fly serious distances? Potatoes just don't do it for me anymore.
