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) for Scout XT.
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'.
