RE: Knight disc extreme (vs.) older disc
I bought my Knight Orig. DISC at my local Scheel's on a special purchase deal they had with Knight. They had about a dozen Orig. DISC's with black comp. thumbhole stocks for $330 they special ordered from the factory at about the same time the DISC Exteme came out. I really like my Knight a lot. It is incredibly accurate, ultra reliable, etc...
I am comsidering buying the Extreme conversion kit for it for one reason...blowback. I don't honestly think that the new discs seal up the primer any better than the old ones when new (unless you like to submerge your muzzleloader). The problem is when I take the Knight to the range I tend to fire 20-30 shots or more, the little ring of plastic on the front of the standard disc, that seals the disc against the breachplug, blows out when fired (especially with Triple 7) and shoots a bunch of fouling back into the breachface and action. The new discs surround a nipple on the breachplug which would prevent blowback into to bolt better. The new discs are also much more durable, withstanding repeated firings without damage. The standard discs blow the seal out on the first shot.
