    My design shoots about 10 feet - using a pretty weak rubber band. It would probably go further with a stronger rubber band. I've made the gun that shoots over 200 ft., but messed up a little, but it still shot far.

    umm ok...if an elastic itself can not shoot tht far then obiuosly it cant shoot something elses that far. my best knex gun uses 4 5mm natural latex elastics and it only shoots bout 100ft. but i may be wrong. i might post an instuctable for a gun that can shoot strait through 3 layers of thick layered cardborad(mind you it has to have the right elastics.
