Best generic load dev video I’ve seen.

100 yards.

You can shoot them at any reasonable distance though. Some guys shoot them at 600 yards to look for a vertical “node” between charge weights, but that’s above my pay grade lol

A few minutes into the video I realized he's essentially doing an Audette-style ladder test (that's normally done at longer ranges) at 100 yards. I used to be a big believer in doing load development that way but when rigorously tested they quickly fall apart due to small sample variability. I'm not going back down that road again.

So the novelty he’s proposing is if you want to search for pressure with a ladder, put them all onto a composite group and you sort of get for free a group size measurement under some degree of variable conditions (?)

Exactly. And since I’ve seen huge differences between barrels, I’m essentially always looking for pressure with a given combo before I do anything else. So it’s a 3 birds with one stone type of thing.
