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.

Mine is a similar process. I prefer to have at least 10 shots for the sample size. I may step 0.1 gr over a smaller range if I am confident where I may pressure out. I will also make my own target board with bright small circle stickers on cardboard with one per shot so that I have an easy record of each POI.
