I just ordered a new barrel for my 110C and the threads appear to be different. The thread pitch is the same, but the threads on my original barrel measure out to 1.050 inches, and the new one at 1.063 or so. (Best I can do with calipers.) The company I emailed said there may be a slight difference in older actions, but I've never heard of such a thing. Just the difference between large and small shanks. Any help?
