All sabot indexing means is orientating the sabot to the bore to get as much of 2-lands on each sabot petal in an 8-land bore. You’re probably wondering what difference this makes? Consider this, the lands are what provides the sabots with pressure to grip the bullet. The more land contact, the more surface tension that provides the sabot a stronger grip on the bullet.
Will this improve your groups? Not significantly but does maintain a better, repeatability for group consistency. Still, it is an improvement IMO.

The nice part is that no extra equipment needed. Just care when loading the bullet/sabot into the bore.
You will probably find that aligning a sabot petal split to the center of a bore groove pretty much gets you there.
Some may wonder why I post so much about my SML experience and some might think I seek recognition. That’s farthest from the truth. What good does my gained knowledge do when my time is up and not shared. My reward is knowing this shared knowledge has helped someone with their SML experience.
For now I’m going to stop posting for a bit as it seems like I’m hogging board space, chuckle.
