Subchapter 8 - STANDARDS FOR INDOOR FIRING RANGES FOR PUBLIC EMPLOYEES
Section 12:100-8.4 - Ammunition

(a) The ammunition used in indoor firing ranges during practice sessions shall be zinc bullets or nylon jacketed or copper jacketed bullets. Service ammunition routinely used by the public employer may be used for qualification sessions.

(b) When selecting the type of ammunition to be used to comply with (a) above, consideration shall be given to a potential problem of "bounce back" of the much harder zinc bullet from the bullet trap in some ranges. Consideration shall be given to the potential eye hazard to shooters which may make the use of the zinc bullets unsafe unless changes are made in the bullet trap.
