I have a tradition buckstalker 50 Cal. I have used this rifle for several years. last season I got a sabot stuck during a miss fire. I got a breach plug removal tool and was able to get the round out. Didn't go to fire the rifle until last week, it would not fire. I tried several different 209 primer's and different loads. I cant think of anything else to do, I have tried tightening the breach more, cleaning, ect. and nothing has worked. Any help before I take it to a gun smith would be appreciated.
