I have a 22 martini that has Canadian ownership marks on the receiver. This particular barrel actually had lumps of both lead and copper fouling on the tops of the lands. Cleaned it, cleaned it some more and finally just kept the barrel wet with hoppe's. Used brand new 22 bore brush that for some reason really fit the barrel tight. About a dozen strokes finally showed some flakes so kept at it. After about 20 minutes patched out the barrel and the lumps were no longer there. Had the same problem with a 1915 vintage 1895 win in 30-40 krag. Had what looked like lumps on top of the lands. 8mm bore brush and no longer there. That one had been soaking with hoppes also. Frank
