Distance Determination

When performing distance determination test firing, special precautions must be taken to ensure safety including the following:

Keep the firearm and ammunition at the firing line.
Load and fire one cartridge at a time.
Fire only towards the bullet trap.
When marking distances to fire known-distance patterns, do not place hands in front of the firearm. Use a steel measuring tape projecting forward of the muzzle or a hanging string in combination with known distances marked on the floor or ground.
Vary the orientation of the target rather than the firearm when simulating angled bullet paths.
Prior to firing, announce your intention to fire.
Clear the firearm before leaving the firing line.
