CLEAN IT . if in any doubt about a pattern or point of aim shift , shoot a couple .
you'd be sorry for not cleaning if the piece failed you at the moment of truth.
if there is any water at all in the woods while i'm hunting , i'll remove forend and barrels and wipe her down and re-oil liberally. i keep a gun oil soaked , 100% cotton bandana stuffed in an ALTOIDS can . actually i keep two on hand , one in my safe , and one in my hillside sportin' room .
