i suppose many of you guys that suggest cleaning your guns after every use have children that are emancipated. cleaning my guns are at the bottom of my priority. my benelli waterfowler gets cleaned once a year and that includes after hunts on saltwater. do you remember what it's like to have young children. i can't wait for my boy to grow old enough so he can help with the cleaning. the question is does it really hurt the bores to have some powder residue sit for a few months. the guns are stowed in a safe with a hydroscopic can.
