IMPORTANT “SAFETY WARNINGS” — NOTE THE SYMBOL:
These safety warnings are for your protection as well
as the safety of others. Disregarding information in
this manual could cause injury, damage or death.
You have a responsibility to obtain proper training on how
to use and maintain your firearm. Certified and
reputable instructions are offered by the National Rifle
Association, the National Muzzleloading Rifle
Association, Black Powder Association as well as state
and local organizations. Seek guidance from an
instructor who is qualified by one of these organizations.
Do not attempt to assemble, load or use the
Muzzleloading barrel until you thoroughly read and
understand the information contained in the shotgun
Owner’s Manual and the contents of this Muzzleloading
Barrel Owner’s Manual.
As the owner of a firearm you must undertake the
full-time responsibility of safe firearms handling for your
own safety and the safety of those around you.
Be certain the shotgun Owner’s Manual and the
Muzzleloading Barrel Owner’s Manual are available for
reference and supplied with the shotgun and/or the

Handle a muzzleloader with the same respect due all
other firearms.
Use Black Powder or Pyrodex only. Use of smokeless
powder in any muzzleloader will result in excessively
high pressures and could cause injury, damage or
death. Do not use smokeless powder; Do not mix
powders.
Never smoke while loading, shooting or handling
powder. Always follow the powder manufacturer’s safety
precautions, as listed on its container.
Never lean over, or stand in front of, the muzzle
anytime.
Always wear shatterproof shooting glasses, ear
protection, and a heavy shirt with long sleeves.
Percussion guns may shower sparks and bits of primer
when fired.
Do not exceed powder manufacturer’s recommended
powder charge. The proper charge for a muzzleloading
firearm is an efficient load which provides consistent
ignition, velocity and yields pressure within safe limits.
Do not use a plastic ball patch. The ball to plastic
patch fit is critical. If improper fit or sharp jolt occurs, the
ball may roll down the barrel, leaving a gap between the
ball and plastic patch. The patch will then act as any
obstruction and could cause serious injury, damage to
the barrel or firearm, or death. WE DISCLAIM ANY
RESPONSIBILITY FOR DAMAGE OR INJURY WHICH
RESULTS FROM USING ANY TYPE OF PLASTIC PATCH.
Do not pour a powder charge directly from a horn or
flask into a barrel. If a smoldering ember is present, it
could ignite the powder charge in the larger container
as well as the powder charge, as it is poured into the
barrel. This excessive amount of powder could cause a
dangerous explosion. Therefore, be safety minded, use
a powder measure or other small measure device.
Never accept or attempt to fire a muzzleloader
charged (loaded) by someone else.
Never fire a muzzleloader unless the ball is firmly
seated against the powder charge. Firing a
muzzleloader with the ball off the powder or part way
up the barrel creates an obstruction and could cause
serious injury, damage to the barrel or firearm, or death.
Be sure all spectators are safely behind you when
firing. Flames and bits of primer sometimes exit to the
side of the firearm.
A misfire or failure to fire can fire at any second. Wait
at least one minute with firearm pointed at the target or
safely downrange.
Consult your local Wildlife or Department of Natural
Resources guidelines to confirm that this muzzleloading
product will conform to local seasonal and legal
requirements.
LOADING YOUR MUZZLELOADER
