A look at Blackburn Defense's video on shot dispersion in target shooting (   • Science agrees: 5-shot groups are pointless  , find their website simulator here: https://blackburndefense.com/tools/di..., and what a person should expect a large shot count target to look like. I build my own simulation in Excel, which you can download here (https://github.com/techdregs/Shooting...) if you want to play around with it.

Simulation is for randomly generated X and Y position, then extracting the dispersion and distributional characteristics and plots. Also calculates probability of shots landing within certain distances, including bullseyes and Circular Error Probable (CEP).
