Whatever you do, do not put a Leupold on an Ithaca Deerslayer. Parts of NY are shotgun and my Deerslayer might as well be a "scope slayer". Two Leupolds, a Simmons and a Zeiss Conquest all went back to the factory for rehab after shooting 385 gr. slugs at 1900 fps. Nikon Slug Hunter seems to be holding up.
