Bonstrosity

I'm thinking about taking my M1 deer hunting this year and I was wondering what my options were for using slugs in a smooth bore barrel. I've heard using rifled slugs w/ a cylinder choke. Or using a rifled choke w/ a sabot...but does anyone know where i could find a rifled choke for the M1...are they the same chokes as the super black eagle? Let me know if there are any other ways to take down my first white tale Thanks Joel
