I've been using Sabotloader's method for over a year now with my Mustang - no grease, no loosening the BP, and especially no grease blow back into the action. It works great. I've never had any problem removing the plug even after a thirty shot range session and leaving the plug in the gun for a few days after the session. This September I shot one five-shot target with the Mustangthree Sunday afternoonsin a row. I cleaned the bore and breech areaafter each session, but did not remove the plug. A few daysafter the third session I pulled the plug with no difficulty. THANKS SABOTLOADER!
