Also, all other persons should remain behind the shooter. Never climb or jump with a gun. You can't control the direction of the muzzle if you stumble or fall. You should safely lay the gun down or hand it to a companion while you climb or jump over anything. Never shoot at a flat hard surface or at the surface of water.
Ammunition can ricochet off of water just like a skipped rock .
Keep the muzzle clear. Never let anything obstruct the muzzle of a gun. Don't allow the muzzle to come in contact with the ground. Guns not in use should always be unloaded. Keeping guns unloaded when not in use is critical to the safety of you and others.
