How to use a shooting range
Learn and follow all the rules of the specific shooting range.
You can usually pick up a pamphlet of rules for free, and sometimes rules are also posted outside the shooting range buildings. Make sure you know and are following all the rules before entering the shooting range.
The only common requirement of every shooting range in the us is that the shooter must be at least 18 or 21 years of age (or have a legal guardian present) and have signed a waiver beforehand. Know that a " hot " range is when the range is active and people are shooting downrange.
