I would start trying to tune a load at 300 yards it will show you a lot more of what your groups are actually doing than shooting at 100 yards.

First thing I would do is a ladder test at 300 yards with different powder charges and the standard COL then think about bullet jump. Here again I wish I was less redneck and more of a intellectual. But alas where two or more of your powder charges come close to each other in the string of shooting your getting closer to your sweet spot charge.

Nomercy or Ridge could explain this better.
