This is something you should of addressed early this spring. Odds are, Knight is going to want your barrel and/or your complete rifle shipped to them. You may not get it back for a month or two. They will find the problem... if not... they' ll likely give you a new barrel or new rifle.

You still never mentioned if you shoot sabots or conicals (or) if you' re shooting with a completely dry barrel (or) what your cleaning methods are. For example: It could be you are using too mild of a bore solvent & have plastic buildup in your rifling.

All you' ve done is complain about your poor accuracy but you really haven' t told us anything you do (or) don' t do!

Another example: I just recently bought a side-hammer that was shot only 8 times in the past 7 years -- that cost $199 new for only $35. The oldtimer said it kept having misfires & no fires so he bought a new one & put this rifle in a garage sale.

Well... after buying it & inspecting it, the original bottom hole of the nipple was way oversized. It cost me only a couple of dollars to fix it. I took it out yesterday & fired 22 shots with it... no misfires & it shoots straight as can be.

We need more info from you (or) contact Knight to get it taken care of.
