When developing a load, I use 5 shot groups until I have the best three. From those 3, I shoot 10 round groups to determine the best. Chrono readings are attached to target. That gives me powder weight for bullet. Process is repeated for powder change. Usually 3 powders. Then best is selected. When bullet is changed, the process is redone.
