The ideal powder charge/bullet weight combination should be one that is tolerant of a charge spread of 0.2 gn. Which is about the tightest you can get in practical reloading, unless you want to weigh each charge on a chemical balance. I spent a great deal of time optimizing the charge for my Eddystone, and found 2 optimum charges (48 and 50 gn with Swiss N140, 168gn HPBT Sierra or Lapua).
Changing that charge so much that the POI is noticeably affected would mean using a charge that is very sensitive to tiny load changes, and would produce poor groups! The difference between best and worst group size in my 30-06 testing was a factor of 3. A 1 MOA load is a potential competition winner. With 3 MOA you can stay at home.
Optimum load first, THEN sight correction!
