I'm learning precision rifle shooting techniques; shooting form & load development.
OCW vs Statistics
I watched 6.5 guys YouTube video describing their Excel Stats tool that can predict a good load from Chrono data alone. The prediction is based on the load that demonstrates velocity flat spot & low ES/SD
I shot 50 rds, 5 shots with 10 powder loads varying by 0.2gr using a Magnetospeed to generate velocity data. I also evaluated each target to calculate MOA.
Surprise! 6.5 guys statistical prediction matched my lowest MOA Target.
I'm a believer in their method.
