A sling shot should be used the same way as a Bow. use the brace and do not grip the handle*. Just let it press against the palm of your hand. Grip the sling between thumb and the knuckle of your index finger. Like you are drawing an arrow. Look at the target. Draw in a smooth motion and loose.


* Gripping the handle imparts torque. Which causes the projectile to curve off to the left or right.
