Blackhorn 209 is designed to work with standard 209 shotshell primers. For the best results, we recommend the following brands:

  • CCI 209M
  • Federal 209A

We DO NOT recommend any of the 209 primers designated for muzzleloaders (Winchester Triple 7, CCI MZL, Federal Fusion, or Remington Kleanbore). These primers are all weaker than standard shotshell 209 primers and do not provide adequate ignition for Blackhorn 209 – especially when used in a poorly designed breech plug system. We also DO NOT recommend #11 percussion caps or musket caps.

THE IMPORTANCE OF PRIMER FIT
The looser the primer fit the more blow back you can expect and the less likely you are to transmit sufficient gas and flame to the powder.  Observe the condition of your primers after firing.  If they are largely black, you are getting excessive blow back.  Below is an example of same brand primer fired in two different muzzleloaders.

If your primer looks like the one on the right, call your gun manufacturer.

Not only does this result in a large loss of energy in the wrong direction, the escaping gasses leave excessive fouling in the breech area.  These gasses can also exit the gun, cause damage your scope and is not considered safe.  Safety glasses should always be worn when shooting a firearm.
