SEAL Sniper proof testing, card splitting from 45 feet slingshot shooting

An example of how I proof test my custom slingshots. When they’re about 95% finished I band them up and check out their accuracy... If they are accurate then they get finished and are sent off... if they don’t pass the test then they are worked on until they can pass... and if they still can’t pass then they’re thrown away. Each future custom slingshot will come with it’s signed proof target!
