Just got a new M2 20 ga. and was wondering about cleaning it. The manual recommends heavy loads for the first 3 or 4 boxes but doesn't say anything about needing to break it down completely and clean it before shooting it. In the past I thought I saw some threads recommending complete tear down and cleaning before even shooting the gun. Is this necessary or can I fire a few boxes of shells first, and then break it down for a complete cleaning and oiling?
