My 12ga 870 with rifled barrel really likes the 3" Winchester sabots in either standard velocity or high velocity (only 100-150 fps extra in the HV' s stated on the box). There' s been a lot of new slugs out since I did my initial slug trials about 4 years ago in my gun, but back then it didn' t shoot any of the Remington, Federal or others I tried worth beans. The Winchester' s group inside a paper plate with open sights at 100 yards. Longest possible shot where I hunt is 75 yards, so I' m happy.
