Run a velocity test over the chrony and then tune depth. Brass prep and consistency is a big part of low ES in my opinion. But let's face it, for most of the ranges guys shoot, an ES of 20-30 isn't gonna make a bit of difference over 10-15.
When I’m starting load development I’ll start with a low charge. Load up some 3 shot groups starting at .015” off the landes or mag length which ever is shorter and seat each group deeper by .030”. Which ever shot best I’ll use that seating depth for my load work. I shoot a ladder over my chrono ( I use magneto speed, must have an accurate chrono for this!) target dosent matter. Look for my upper flat spot near max. Then I’ll load up 5 shot groups and fine tune my seating depth in .005” increments. If you don’t have a magneto speed or labradar then you could do 3 shot ladder test at 300 yards. This is my method that’s worked well for me. Yrmv
