The story of my Slingshot Rifle....<br><br>After I shot holes into my wall by accident I decided to change the ammo.... So I went to the local Store and came back with.... Yes, with airgun BBs. <br>Their diameter is about four and a half millimeters, and they are the cheapest ammo you can imagine.... 1500 BBs cost me about 7-8 Euros.... But theres a BIG disadvantage: Its difficult to shoot because the BBs are difficult to handle....<br><br>They also need a long draw length for getting enough speed to penetrate properly... (That means they should get through 3-4 layers of cardboard)<br><br>The solution of all that is a slingshot that <br><br><br>-> shoots 4.5mm steel balls<br>-> is easy to handle -> should have a self reloading mechanism<br>-> has a long draw length<br>-> shoots as accurate as possible<br>-> has enough power to penetrate cardboard/ thin wooden plates<br>-> is easy to build...<br><br><br>And thats what I built:<br><br><br><br>By the way, the scope is about 30 cm long...<br><br><br><br>It has a changeable fork, just for the case i`d like to put other bands on it....<br>It is also useful because you can pre-adjust the direction of the shot.<br><br>As you can see, I just fold the rubber bands, put a tiny bolt between it, stretch it and put it into the slot. It is The easiest and fastest way putting bands on (imo). It also prevents from handslaps in case you use it on a normal slingshot.
