When I lived in upstate NY, thats all we could use was a shotgun w/deer slugs. All our shotguns were the rem 870. We put rifled barrels on them made by Hastings. 3" Mag BRI saboted .50 slugs. 50yds, tac driver, 75 yads still on a paper plate. Nothing beyond that was a ethicle shot IOHP. With a smooth bore 50yds was our limit.
