sweeping someone on the range with a pistol is an entirely DIFFERENT animal and comparing apples to oranges.
as to the rest of it,
whatever. You can get into this as detailed as you want, or as minimal as you want. Just because someone else doesn't care to make a full DOE and do a complete and detailed statistical analysis doesn't make them a bad reloader.
Or you can just shoot as many chrono's as you want and see which ones work the best.
