well, today with my cousin chase, we finally went out and bought about 4500 BB's, and tested my gun out. i encountered several problems, most of them were jamming, but other than that, it performed perfectly. when chase had gone inside, i took a popcan and set it on a branch, and kind of emptied the entire gun into it (300 capacity) the popcan is incredibly contorted and mangled. soon, when i get home (i'm at my cousins house now) i'll take a pic of the damage. its absolutley insane what this thing does. i'm hoping soon that i will get a long pellet gun barrel attached to it, which should increase its performance greatly.
