POI shift with 1 grain powder difference?

Just curious what you have found your POI change has been when doing ladder tests in 0.5 or 1 grain increments. If all else is equal, does each shot with a different charge weight hit the same general area or can they be widely scattered?

From my experience it depends on where you are in relation to your node. It could drastically change your poi or it could be exactly the same. Lots of factors here but ime that’s the just of it.

Seating depth node or powder/velocity node?

In my experience, nodes are not repeatable and therefore not real. At sufficient distance, the fps difference from the extra powder will move poi higher by some amount.
