I have a Mossberg 930 SPX that I shoot on occasion. It's mainly for home defense. I just shot about 16 shells 00buck through it. The gun was clean before that, because I had field stripped and cleaned it about 2 months ago after a day of shooting it. My question to you guys is how often should I field strip it after shooting it? I mean I always clean the bore and chamber even if I shoot three shells through it. But not really sure when to do a complete field strip.
