Are 2-shot test groups as statistically significant as 10-shot ones? That is, the same size?
2 shot groups are to find the rifle's various "nodes". If you shoot more than 2 shots, then which distance from which shots represents the true "node" spread?
Once you get the best group at that particular "node", adjust your POI to your liking. Theoretically, all future shots should land between the 2 original "node" shots.
However, we both know the human factor enters in, spoiling things. AND...as the barrel heats up, shots will wander outside the "node" group size.
The people at RAS Tuner say you can move the Tuner as the barrel heats up and keep the group size. I haven't tried that as of yet, as it would take some trial and error to figure which direction and how much.
As to your 2 group vs 10 group significance...the 2 shot group is the building block and the 10 shot group is the confirmation...THAT...the RAS Tuner did it's job.
