I know a lot of people claim they do not have problems with breech plugs getting stuck, but I am not one of them that can say that. The first day I shot my new Black Diamond XR I stuck that breech plug so tight, I ended up breaking that wonderful wrench (junk) that came with the rifle.

When I got my knew Knight Disc, I was more careful.. and it still had to be put in a vice and twisted out. So the best thing I found is what I call my ten shot rule. After ten shots, I take my wrench and twist that breech plug. Since my rifles are not fancy break open, this gives me time to clean the hammer striker, the breech area, the nipples (all but my disc shoots #11 caps), and gives me a break from pounding lead down range.

I am real glad to hear that you got the breech plug out. I know how frustrating that is.
