I bought a new .920 bull barrel for a 10/22, and I can't clear it after I'm done shooting. The unfired round can't be extracted, and has to be fired with a dropped magazine so it extracts the empty casing itself, or I have to pry the round out of the chamber with a screwdriver. All other operations are normal. For the record, the standard barrel works flawlessly. Does the barrel need to wear in, or am I overlooking something?
