You can start by hand lapping the bolt locking lugs,hand lapping bore,bolt cocking notch,pillar bed,remove pin that locks bolt while on safe,rod that locks striker,by ALL MEANS do a good trigger job on it. Think that will do you for starters? I take things a step or 2 farther by blueprinting action while I'm waiting on new barrel to come back from being cyrogenically frozen,and work up a good load for it.
