Skip the magnum buckshot rounds for home defense. Typically you get 3 extra pellets over the standard load, and at a lower velocity, yet with greater recoil, as you noticed. You'd be better served with the reduced-recoil LE buckshot rounds.

The sabot slugs showed only a slight improvement over the regular slugs, but when I stepped up to a dedicated slug gun (solid frame, fully rifled barrel) the sabot slugs gave pretty impressive accuracy.
Interchangeable chokes are fine for rifled slugs. I don't know where people get some of this information. Maybe certain chokes won't work with sabot slugs? IC is usually recommended on the box of rifled slugs for accuracy, but they shoot just fine out of my modified chokes.
