Hello! Today I got the Cobra Commando 80 ib "Pistol Crossbow". Without a manual..."So": 1. Should the bolt be placed as far as possible towards to the gunman? In a Video someone said, the bolt should barely touch the wedge (but in my opinion this is illogical, becaus the string would "kick" the bolt then - instead of "pushing it all the time"). 2. Is it possible to shoot longer bolts with my crossbow (longer than 16 cm) ("is it recommended")? 3. Are there bolts to buy with a length of about 28 cm (ca. 11,2 inches)? So the bolts would be overtopping, and I could use other bolt-heads. Thanks and bye bye!
