Probably the only people that might be interested in this are the ML hunters in the Pacific Northwest where we can not use 209 ignition.
But Knight does make a Western Kit to allow the Knight DISC Extreme to shoot either #11 caps or Musket caps. The new Western Kit has been modified was the addition of a protective hood on the bolt. The hood has cause some concern about the ability to post a Musket cap. #11's are not a problem at all...
So for information...
There has been some question as to whether you can cap the
new Knight Western Kit with a Musket cap... short answer - yes!
But, it needs to be the right capper. Most of the plastic type Musket cappers on the market will not work, they are to large to get into the opening of the hood of the bolt.
The Tedd Cash brass capper will work to install musket caps on the nipple post...

With a slight modification to the brass nose of the capper it will even be more convienient to use.
Here is a set of pictures showing the the process using my Knight DISC Extreme 52 cal elk gun.
