12 commandments of firearms safety
1 ALWAYS treat every gun as if it were loaded.
2 ALWAYS be sure the barrel is clear of any obstruction.
3 ALWAYS be sure of your backstop, what lies beyond
and the safety of bystanders before you shoot.
4 ALWAYS use clean, dry, original factory- made ammu-
nition of the proper type and caliber for your gun.
5 ALWAYS wear ear protection and safety glasses when
shooting.
6 ALWAYS carry your gun so that you can control the
direction of the muzzle if you fall or stumble.
7 NEVER shoot at a flat surface or water.
8 DO NOT leave an unattended gun loaded. Guns and
ammunition should be stored separately, locked if
possible, beyond the reach of children and careless
adults.
9 NEVER allow your firearm to be used by anyone
who has not read and understood this instruction
and Safety manual.
10 DO NOT point any gun, loaded or unloaded, at any
undesired target.
11 NEVER fire your rifle near an animal unless it is trained
to accept the noise: an animal’s startled reaction could
injure it or cause an accident.
12 NEVER drink alcoholic beverages or take drugs before
or during shooting, as your vision and judgement could
be seriously impaired making your gun handling unsafe.
