You may have already tried this, but have you really cleaned your Nula. The only thing I don't like about mine is that it likes to be fairly clean. After about 50-60rounds it starts to open up. Clean it good give it 3 or 4 to foul the barrel and things are good again. Mr. Forbes told me to clean it after each time I shoot it after a range session. I didn't believe it was necessary. I've since found out with this rifle anyway it is.
