Tom,

You forgot the Remington Core Lokts! They are definitely one of the top performers, depending on each particular gun.

Also, don't mix the sluggers and buckhammers, with the sabots shells. Those two shells have no sabots and can/will leave a lot of lead in your rifling. You must clean your barrel thoroughly after each time you shoot them.

I personally would not shoot non-sabot slugs in my rifled guns. That is only my personal choice though.
