im still working on the video, im going to buy a bigger cylinder so itll shoot bb's and toothpicks, so you can see how good it fires, because you cant see 4mm peaces of wire shoot at height speed with my camera.
if your interested in this comment so i can make a tutorial.
i shot the gun at a big box from 5ft away, and it made a very loud impact for a little 4mm peace of copper wire. so i have no idea of its range but i know its well over 5ft, and the accuracy is rly good even with a small barrel.
