Distance at range

3 - 5 yards shooting paper

then move to 7 yards....10 yards....15 is about max for a small snub 38 revolver or pocket semi like a 380 (for the average person)

I've seen experienced shooters hit steel plates at 75 - 100 yards pretty regularly with snubs

Important thing for a new shooter is to learn trigger control

If a using a hand gun this is best done shooting a revolver with a decent trigger..... double action

Always go back to the basics
