The first to try would be..

Lightfields
Winchester Partition Golds
Remmington Core Lokts


TheLightfields are great generic slugs, they seem to work well in many guns. Unfortunately they are sub-par when comparing down range trajectories to other premium sabots.

Winchester Partitions group very well out of the right guns and have great down range trajectories.

Remmington Core Lokts group very well out of good amount of guns and have possibly the best down range trajectories available.
