Nerf Vortex "Rockets"

Times have changed a bit and there is even more of a focus on safety especially at scenario games where the big guns and ammo tend to show up. About the only allowed ammo at most big games now is the Nerf type. The vortex is the preferred (approved?) ammo because of it's size and missile like shape which makes it fly nicely. While it won't leave a mark these also make no mess and are great fun to just play around with at home (using a launcher or not). Just remember to be SAFE and never shoot anything (nerf or not) directly at someone from a launcher. Shoot it up up and away and let them catch it on the way down. :)
