put in projectile in the pouch supplied
that thing between two elastic looking bands
grip pouch while holding the projectile in place
pull back too a comfortable tension
aim at say a tin can about 5 yards, 15 foot,4.6metres away from you
when you are happy with your aim
unpinch fingers holding the pouch
the projectile should wing it's way to the target
if it falls short,pull back harder
repeat until proficient
hope this helps
if i've missed anything
please carry on the thread
