I use forest foam bore cleaner, problem is that bit of flexible tube is just too short and foam gets everywhere, so to keep it out of the action I use another piece of flextube 3/8 OD x 1/4 ID approx 9-10" long. Using an insulated scrwdriver, or some such, apiece of dowel, apiece of steel, slightly larger than OD of tube on can (which is 5/16" dia) force screwdriver into 3/8 dia tube for 1/2" pour boiling water over tube and screw driver end for afew seconds then do the same with cold water, remove driver, you've now swaged the tube ID to the same size as the can tube OD. Firmly push 9-10" tube into rifle action, push can tube into swage making a water tight fit, wrap cloth over stock,( you're bound to get a drip when removing can, sods law) fill barrel with foam, remove can, allow excess foam to empty into barrel, let it stand for 15 mins or so, then remove tube from action, walla, no mess in action or trig mech. callie
