I have a Rem. 11-87 with a rifled barrel. I've used the Winchester 385gr partition sabots for the last 2 years with decent results. Two weeks ago I did an experiment. I bought 1 box each of the 2.75 inch Win partitions, 3 inch partitions, Hornady magnums, Remington core lokt and the Win Platinum Tips. I shot 50 yard groups. The three best 50 yard groups were the 2.75 inch partitions, the Platinum tips and the Remintons. I then moved to 100 yards and shot 1 box of each of those 3. The Platinum tips are the best & I am switching to them for this season. They group about 2.5 inches @ 100 yards. I will tell you that I discovered that my barrel has to be cleaned after 5 shots or accuracy deteriorates big time. I think it has to do with plastic fouling from the sabots. The Platinum tips are 1700 fps vs 1900 fps for the core lokts & partitions. The 3 inch partitions @ 2000fps were not bad but they feel like the paint horse that made me fly when I was 8 years old.
