CVA™ Blackhorn 209 Breech Plug Installation Guide

Blackhorn 209 loose powder has become a frontrunner for black powder shooting and is one of the most efficient black powders on the market. For CVA muzzleloader owners, this powder option is only achieved through the use of the CVA Blackhorn Breech Plug. The CVA Blackhorn Breech Plug has a bored out flash-hole that allows the powder to ignite closer to the 209 primer, creating a faster and hotter ignition. This allows the use of Blackhorn 209 loose powder in the CVA Wolf, CVA Optima, and CVA Accura muzzleloader models that were made after 2010.

Accessories and Parts needed for installing CVA Blackhorn Breech Plug

How to properly install the CVA Blackhorn Breech Plug:

Step 1: Remove any debris and powder residue from the breech area.

Step 2: Finger-tighten the CVA Blackhorn Breech Plug until the breech plug is flush with the barrel – CVA Anti-Seize Stick is recommended for use on the threads during this step and will aid in future use of the breech plug.

Step 3: Tighten the breech plug with the CVA Breech Plug Installation Tool approximately one half of a turn, or until fully snug against the breech – there should be no gap between the breech plug and the breech.

Step 4: Test the functions of the muzzleloader: i.e. the trigger, the break action, and the hammer assembly to make sure the breech plug is properly seated.

Step 5: Loosen the breech plug using the CVA Breech Plug Installation Tool to complete installation. The CVA Blackhorn 209 Breech Plug should be able to loosen and tighten with just your fingers.

Important Reminder: Be careful when applying Anti-Seize on the breech plug as only a small dab is needed to be effective. Applying too much Anti-Seize can cause the breech plug to seize even more.  

If the CVA® Blackhorn™ Breech Plug is properly seated, then the break-action will close, the trigger assembly will engage, and the hammer assembly will cock correctly. If you cannot do any one of these three actions, the breech plug is not fully seated. This is a built-in fail-safe to ensure proper installation before firing. Simply repeat steps 3 and 4 until the breech plug is fully seated and your muzzleloader is functioning correctly.
