And how do sabot slugs spin, exactly?
Sabot slugs require a RIFLED barrel. period.
"Rifled" slugs have raised ribs that happen to resemble riflingto give them a "squash" factor to be safe in a variety of chokes. The ribs are diagonal in orientation to help prevent gas blow by in the barrel.
They are stabilized by their "weight forward" design. They naturally fly with the heavier part forward. The rifling has absolutely nothing to do with outside the barrel performance.
