Thank you as always Clark. I pulled apart the bolt and gave it a cleaning, in addition to a quick cleaning of the bore, I do intend to deep clean it, just didn't have the time this evening. Ran a couple snap caps through it afterwards, but operator error kept me from running through them very reliably. Guess I'm actually going to have to thumb through the manual, this girl's operation is a little more sophistamacated than my old Mossy 500.
