So my plan was to take a "middle of the road" powder charge and do a seating depth test, and then refine where i went from their with a ladder test. Is each process time critical or should one be done first. I know that after the first go around i had planned to go back for fine tuning, but is there a series of events that makes things go faster or gives better results? My plan example: 223 rem 30" shilen barrel and savage action. Lapua brass 1. choose 24 grains varget. I have been shooting 24.4 2. Do a berger VLD seating depth test. 3. Do a ladder test in .2 or .3 grains from 23-25 grains and stop when i see pressure signs. 4. Check a similar powder like h4895 to see if it performs better in the same ladder test. 5. Check a different bullet of the same weight like eldx, and a match king. 6. depending on results try a different shape like a 77 gr MK If i dont have a decent shooter at this point i would be off grid and begging for help.
