The guys are spot on, those new SST slugs surpass the ballistic performance of all but really stoked-up ML loads.

The icing would be accuracy. It would be straightforward to demonstrate that a ML with the same bullet is more accurate than a rifled shotgun barrel with these slugs. I have yet to see a shotgun that consistently shoots 1-1.5 MOA but it's easy with a ML. Not only don't you want the bullet to travel, but you want it to hit the deer you are aiming at. BOTH reduce the chance or errant rounds.
