I shot 110 grains of Triple Se7en 2f with the standard Extreme plug today and found no trace of a crud ring at all. In fact I kept using the same swab patch over and over for about three swabs before I changed to a new one. So far it is a nice rifle to load and shoot.

No it is not that if I screw it in and put the adapter into the bolt face I can fit a 209 in the end ..the combustion end of it looks just like the conventional FPJ breech plug. I know what your talking about and I may try that at a later point. Thanksw

Wow that is really good, 3 swipes with the same patch, I've never done that with any rifle with 777.
That is great. Chap

I think that what you have is a breech plug adapter for a #11 cap. My Knight Disc came with an Orangedisc that held a #11 cap. So my guess is Knight still puts them in with all their guns since some states only allow FlintLock and percussion cap ignition, not 209 ignition. Chap

If I am not badly mistaken he has the non full plastic jacket adapter. This allows shooting 209 primers without the red jackets.

Personally I kind of like these red primer jackets.. they are easy to load and unload, and easy to carry. I take out a small bag of 20 and when I am done, drive out the old primer using a bolt and a large nut to rest the jacket on. Then reload them and am all set for the next shoot.

I agree, especially while hunting with cold fingers.
