The way I work a new load for a new gun is different than a new load in a gun I have already made other loads for. With a new gun I take the start load and subtract it from the maximum load. That gives me the number of grains that I have to use in my load workup. I divide that number by 10 and make five of each step. At this point I am looking for two loads that produce the best groups. Not that they will be acceptable groups but it will give me a new range of powder charges to narrow down for the tightest groups. I continue the process until I get to 0.1 grain increments and I select the three that make the tightest groups and then test them over a couple of months to make sure they are consistently accurate. The best selection for me is the load right in the middle of the three or more accurate load. This has provided me with the most consistently accurate loads.
Here is the form I use in my workup and keep for my records:
