I find jump does not matter. Its about where the bullet leaves the barrel in the harmonics. There will be multiple seating depths that may work well, you just have to find one of them. Tuning .003 adjusts when the bullet leaves the barrel to a stable point in the harmonics and will generally find one to two good nodes. To be clear i mean 1, 5 round group at each seating depth, with 5-7 seating depths. Your talking 25-35rnds total and your done.
I went from 1.5in groups down to .75in groups in my budget hunting rifle, all i did was 25rnds, 5 round groups, 5 groups total.
I tried measuring off the lands and using the comparitor tools and had nothing but problems as well as wasting a lot of bullets, powder, and primers trying to do it. The lands erode as you shoot, your measuring off a moving point that is guaranteed to change. I have seen people on YouTube use much bigger jumps in seating depth and have trouble finding a good node. I found the method from eric cortina doing the 0.003, and it worked like magic
