You can do as you want, but let me just talk for a second. A lot of people reference that Berger recommendation and a lot of people have tried it. What I'm saying and others are saying is, you're jumping over the potential sweet spot for the bullet you want to shoot by moving in 0.040 increments. That's huge in seating depth. I don't like wasting bullets, powder, time, and barrel life to chase my tail with inconclusive results. I don't think many people enjoy that. I love to shoot but I love results and I love learning while I do it.
Having said that, I like using methods that deliver results and give me the results I want and results I can trust and reference. If you are serious and want to find the best results in the least amount of time, then start .020 off the lands and work back in .005 increments until you find a seating depth node. You're going to shoot 20-50 bullets doing this. The fact is, you're going to shoot 20 bullets doing Berger's recommendation and you're more likely going to be more frustrated after that test than with what I and others have recommended. If the Berger test is inconclusive than you have to start over or try and pick a seating depth and work around it. I can almost guarantee you'll find good groups with one or multiple of the seating depth jumps that you test with the method I suggested. Then when you are done you have definitive results and a bullet jump to work with. I don't like repeating myself or getting lost in the middle of something. You have to sacrifice some more time and bullets initially, but if done right, you'll come out with good results and a path to follow. Again, do as you want, myself and others are just trying to help so you get the results you're looking for.
