what my favorite slingshot ammo is ceramics mud balls. Healthy and easy and fun to make myself.
And I have two types mud balls, one is safety ball, no bounce when hit object.
Another is hard-core balls, as powerful as steel ball.
When i saw the video i wod think to my self: it´s a lovely way to shoot. Immediatily i buy 1745 and now i am trainning... try yourself too.
I've learnt that surgical tubing is the mosted used for serious homemade slingshots. But in my opinion, 'homemade' doesn't mean you must use material in home. You can use any material as long as you make them at home. I used to buying commercial tube in meters and make my own bands at home which should be 'homemade' too.
