Best of luck to you....handloading is about trying to do better!
Indeed it's essentially a personal six-sigma manufacturing...
Just read your earlier post again.
Ground is soft, but it's more like a shooting stick type set up. So I am not worried about it being to hard.
Rifle sits in a padded wooden cradle. Plus military sling plus elbows on knees. So it's pretty stable.
I have run some factory loads from cheap range benches using a pack as a rest and done well under MOA, but I was still figuring out how the PO had it sighted at that point.
So far w/development I have gotten them into contact. Then I went back for smaller steps around the contact charge. Then I got that diagonal stringing on the lower side. I had seen vertical string on earlier steps, but the there was barely a breath of wind that day.
So I looked for the "why" and I noticed that I had consumed mass of primers of .33, .36, .37gr.
Hence my question about primers as the other cartridge measurements were as consistent or more consistent. For that string.
