My dear brother visited over Christmas and brought my nephew with him. a 15 year old boy who hasn't shot a slingshot in his life before. Of course that had to change! I decided that paint balls would be a good start, as I didn't really want to risk any catastrophic injury that would spoil the party... so I bought a pack of 500 .62 cal. powder balls, banded up 3 Rambones with weak bands (TBG straight cut 1,5 cm single layers) and put a Zombie target 15 meters away from the rain safe garage shooting stance. I taught the boys how to shoot target style (sideways, anchor point = corner of the mouth) and we started to shoot. At first they got good results, then they experienced a few fork hits, tried to avoid those, which lead to nothing BUT fork hits so I taught them how to flip and how to twist the pouch. That did the trick. The poor Zombie got chalked up but good! The fun started when we turned to volley shooting. All three firing at once. What a blast! Towards the end, when the women already started to call us in for more food, I took a really strong slingshot with hand protection and fired some high speed shots into the Zombie target. Amazingly, the powder balls did NOT explode (like they did when shot from the weak bands) but cracked the hard shell of the 3D target! You can see some of the intact balls sticking in the holes in the last two pictures. I guess those would have been very painful hits at a paintball range. Shooting paintballs is a great way to learn the sport safely and to build up confidence. Both guys now wouldn't have a problem shooting steel balls. But if I would have given them steel balls right away... oh my.
