can someone under 18 years old attend firearms class?

We must abide by Nassau County Rifle & Pistol Range rules, which are the following:

Persons 12-17 years old can shoot firearms at the range, but .22 caliber rifles only. They must be accompanied by a certified NRA instructor (which we are) or a parent who has taken the NYS Hunter Safety Course. We will need birth certificate and school photo id, or passport for the minor.

Can i purchase ammunition at the range?

Nassau County Rifle and Pistol Range does sell ammo, but it is not a good idea to rely on them to provide the ammo for your class. Due to recent events, there are intervals of ammo shortages and if the range is out of stock on the day of your class, you may not be able to shoot. It is highly recommended to purchase your ammo far in advance of your class date.
