    							Muzzleloading Shotguns
    Replicas of original muzzleloading guns are as faithful to the original de-
    signs as possible. For this reason, replicas cannot be made with many of the
    refinements and features the shooter has come to expect as standard on
    modern cartridge firearms.
    Each shooter should remember that now, just as in colonial days, there is
    no way to build a shotgun to absolve the user of the need to use good judg-
    ment.
    When handled properly, a shotgun is a safe and enjoyable firearm to shoot.
    If abused, harmful consequences can result. Remember, this shotgun should
    be treated with the full respect due any firearm.
    You should know that the warranty applies only to parts of this product
    which have not been altered in any way. Therefore, it is important that you
    take the time to familiarize yourself with each part and its function prior to
    shooting.

    							A. IMPORTANT CAUTIONS
    1. Always wear shatter proof shooting glasses and ear protection.
    2. Use blackpowder only. (See page 4.)
    3. Never fire a muzzleloading shotgun unless wad (or ball) is firmly
    seated against powder charge.
    4. Do not exceed recommended maximum powder charges. (See page 9.)
    5. Never lean over (or stand in front of) muzzle at any time.
    6. Never attempt to shoot out a wad (or ball) which is not firmly seated
    against powder charge.
    7. Treat a misfire or failure to fire as though the gun can fire at any
    second.  (See page 23.)
    8. Do not use any form of wadding except those recommended by CVA.
    (See page 14.)
    9. Handle a muzzleloading shotgun with the same respect due all
    firearms.
    10. Be sure all spectators and bystanders are completely behind you when
    firing. Flames and cap bits sometimes exit to the side of the gun.
    11.Never smoke while loading, shooting or handling black powder.
    12. If one barrel of the muzzleloading shotgun is fired, remove the percus-
    sion cap from the unfired barrel prior to reloading the fire barrel.

    							B. INTRODUCTION
    1. This manual contains instructions, cautions and dangers for the safe use
    of CVA muzzleloading shotguns. They should be FOLLOWED COM-
    PLETELY.
    2. When properly handled, a muzzleloading shotgun is safe and enjoyable
    to use, if you follow a FEW BASIC RULES.
    3. There is no way to build a muzzleloading shotgun to absolve the user of
    the need to use GOOD JUDGMENT. Do not abuse your muzzleloading
    shotgun.
    4. Your muzzleloading shotgun should be treated with the RESPECT DUE
    ANY FIREARM; in addition to the specific cautions and dangers in this
    manual.
    NOTE:If, after reading the instructions, cautions and dangers contained in
    this manual, you are not willing to accept the responsibilities in-
    volved in shooting a muzzleloading shotgun, return the gun (or kit)
    to your dealer before firing or building or write directly to: CVA,
    Customer Service Department, P.O. Box 7225, Norcross, GA 30071.
    CAUTION: If you sell, trade or give this gun (or kit) to another person, make sure
    you give the new owner a copy of this manual or inform him to get a free copy from
    CVA.

    							C. BLACKPOWDER
    1. BLACKPOWDER is the only safe propellant to use in any muzzleload-
    ing firearm. Pyrodex RS is an acceptable substitute.
    2. The term BLACKPOWDER does not mean any powder that is black in
    color. Modern smokeless powders are also black in color. Always be sure
    that the blackpowder used is commercially manufactured blackpowder
    for use in muzzleloaders, offered for sale by a reputable dealer. TAKE
    NO CHANCES!!
    3. The applications of the various granulations of blackpowder are as fol-
    lows:
    a.1f or fg—Coarsest granulation, used for model cannons and very large
    caliber rifles.
    b. 2f or ffg—Less coarse granulation, used for rifles .45 to .58 caliber
    and the only granulation for use in muzzleloading shotguns.
    c. 3f or fffg—Standard granulation, used for all revolvers and pistols
    and all small bore rifles (.40 caliber and under).
    d. 4f or ffffg—Fine granulation, used only as a primer for flintlocks.
    4. Blackpowder should be stored according to manufacturer’s instructions
    listed on container. Local fire regulations should be followed.
    DANGER: Use of smokeless powder in any muzzleloader will result in excessively
    high pressures and can cause serious damage to the muzzleloading firearm and
    possibly to the shooter.
    4 
    						
    							CAUTION: Never smoke while
    loading, shooting or handling
    blackpowder. Always  follow
    manufacturer ’s safety precau-
    tions, as listed on the container.
    D.PREPARATION BEFORE
    LOADING
    NOTE: T h e  s hotgun must be
    cleaned prior to loading
    to remove the factory ap-
    plied preservative and
    any foreign matter that
    may be in the barrels.
    1.Lock function and adjust-
    ment.
    a. Set the right hammer on
    HALF-COCK. At this set-
    ting it should not be possible to manually push the right hammer
    forward and the hammer should not move when the front trigger is
    pulled.
    b. Check the left hammer with the rear trigger in the same manner.
    5 
    						
    							c.Pull each hammer to FULL-COCK position. The hammers should
    be securely locked in that position. It should be impossible to
    push the hammers forward manually. Pull each trigger separately.
    Take care not to let the hammers slam onto a bare nipple by
    restricting their forward travel with your thumb. Allowing a ham-
    mer to hit a bare nipple with force can cause the end to flatten
    and create difficulty during installation and removal of percus-
    sion caps.
    d. If the locks do not operate properly, removal and adjustment by
    means of turning the sear adjustment screw is necessary (See
    Figures 2-4B).
    IMPORTANT: The sear must have secure engagement with the full-cock
    notch (See Figure 4A). This prevents a dangerous or lightweight trigger
    setting as pictured in Figure 4B.
    IMPORTANT: Do not set either sear so that the triggers require less than
    four pounds of pull to fire. Such a light setting could cause the second
    barrel to fire from the recoil of the first.
    CAUTION: Do not reduce sear engagement beyond full face of the
    sear point (See Figure 4B). To do so will cause rapid wear of the sear
    point and notch, creating the possibility of accidental firing.

    							E. SUITABLE BLACK POWDER CHARGE FOR
    MUZZLELOADING SHOTGUN
    1.The correct powder charge for a muzzleloading shotgun is never weighed.
    It is determined by volume measure and the same measuring device is
    also used to achieve the volume measure for the shot charge as well.
    This type of measuring is known as Volumetric Balanced Loading.
    2. A volumetric balance load will provide the most efficient shot pattern,
    regardless of the amount of shot chosen. Adding more powder will re-
    sult in a wide dispersion of the shot pattern; less powder will result in
    insufficient energy per shot pellet.
    a. Volumetric balanced loads will result in velocities from 1,000 to
    1,050 feet per second, regardless of the shot size or shot charge
    chosen.
    3. There are only three loads to be used in a 12 gauge CVA Shotgun:
    CAUTION: The adjustments mentioned in 1d are very critical. If you
    do not feel comfortable making them yourself, have a competent gun-
    smith make the necessary settings. DO NOT operate the gun with
    any faulty mechanism.
