The Accutips have been accurate in all the slug guns I've used except one. That one hates everything. They may not be the most accurate in every or any gun but they should be accurate enough.
I have had good results with the Hornady SST slug in my Ultra Slug but it is a 20 ga. It is as accurate as the Accutips but they shot to a very different place.
In 12 ga I recently found some inexpensive sabots from Brenneke that brought a finicky Mossberg to trustworthy again. It loved the Federal sabots with the Barnes Expander but hates the copper sabot Federal now uses. They also showed promise in a Beretta 391 but that was only 3 rounds as that gun like Lightfield Hybrids which I have a fair bit. The biggest negative is the slug lands a good 6" lower than the current slugs at 50 yards so will need considerable adjustment if I choose to use them.
