I got 50+ ft with one rubber band.

How in the the hell do you shoot this? The band is supposed to catch the bullet but it just ejects the bullet out the side.

author
rec0n (author)Smasher5552010-07-24

change the blue rod of the bullet to an orange connector.

author
Smasher555 (author)rec0n2010-07-24

rec0n (author)Woox2010-04-08

It uses about as many as the Z35. tie your bands together.
