A kettie sport-shooting athlete, should be able to “knock down” the steel targets at distances of 10 m, 15 m, and 20 m reasonably consistently to be competitive. The SASF Standard discipline targets are designed to require a minimum of 2 lbs (2x British pounds) of energy to knock them over. In real terms, this equates to shooting an 8 mm (carbon steel round ball) with a mass of not less than 30 grains (1.94 grams) and not more than 35 grains (2.26 grams) at a speed that generates in excess of 2 fp/energy. For example, an average steel ball at 32.6 grains (2,11 grams) at 200 fs generates 3 fp/e to 2 fp/e at 20 meters, and 280 fs generates 6 fp/e and 4 fp/e at 20 meters. Thus, speed is not the issue; it is about accuracy (external ballistics); in other words, placing the precision (grouping) of the kettie on the target.
Round-Ball (Kettie/Slingshot) External Ballistics (Accuracy), is actually very complicated, and we suggest you read: Ketty PHDee articles on the Ketty.co.za website. Note that Firearm BC (ballistic Co-efficient) ballistic solvers (calculators) – nor intended for “round ball” ballistics, could provide misleading information. Know this: there is no such thing as a “flat shooting slingshot. ” The moment the round ball (projectile) is released from the pouch, “pellet-drop” due to gravitational forces takes immediate effect.
