Re: most accurate long range shotgun.
I have a Benelli M1 with a rifled choke. Seems I can usually get 3 holes touching at 100 yds. (from a rest) with Hornady SST slugs and a cheap Simmons 1.5X -4X shotgun scope. Saboted slugs are HORRIBLE!
Yeah, a fully rifled Benelli barrel would be nice but here in the west a Browning A-Bolt .300 Win. mag rifle is my toy of choice.
Later I'll be getting a Desert Tactical Arms in the same caliber. Just have to wait for a year backlog.
