Thread: Testing a conventional approach to load development

To be clear the "changes" visible in 3 shot groups are within the variation that happens within 3 shot groups of a single load. At present there is no evidence at all of any difference between the seating depths. SD is meaningless for a sample of less than 10 at minimum, more like 20-30. I've loaded 20 of each and I'll shoot tomorrow or Saturday and post results.
