Would appreciate any guidance for an slightly older topper 12 gauge I think its an 80's model. Went through all the shimming barrel lug didn't touch the latch engage ment underlug. It seems to be latching up too close to the top of breech, most of my other collection of fie/winchester/marlin single shotguns lock up alot lower again the action. Any ideas? Thanks
