you ain't hunting elk with a .36 skwerl gun good find on the pedersoli. make sure to clean out the ante-chamber with a small bronze bore brush.
i'd say to stop yer searching around for used and get a new lyman trade gun in .54 bore - added to yer .36 you'll have a pair of guns that'll do things that a .45 would marginally do and be either under gunned for elk or over gunned for skwerls.
