Abstract: There is a disclosed method and apparatus for trapping bullets in an indoor range having a first end and a second end by use of a bullet trap. The bullet trap is formed from an upper plate and a lower plate and a liquid-filled trough. The bullet trap is positioned near the second end of the indoor range. The upper plate and said lower plate converge together toward the second end of the indoor range to form a horizontally positioned slot between an upper end of the lower plate and a portion of the upper plate. The upper plate preferably curves downwardly between the slot and the second end of the range and ends in a generally vertically downward orientation pointed toward the liquid filled trough. Bullets fired into the bullet trap from the first end of the range pass through the slot and are trapped in the liquid filled trough. The method keeps airborne lead concentrations at low levels.
