No, we don't recommend shooting stones out of modern adult slingshots. However, we know folks will do it anyway...so we suggest you use a bandset that is made for shooting stones. This kit includes one RockerChucker Linatex bandset($10 retail) and two sets of FlipClips($10 retail).
The RockChucker bands should be fitted to the Scout in the 'over the top' or 'OTT' configuration ONLY!! Do not attempt to shoot stones 'through the forks' or 'TTF'.
