A lot of handloaders for typical hunting rifles would do well to carefully listen to that segment a dozen times or so.

Well, you're right with what I think that you are implying, but I doubt that many will really get the significance of what is being said.

Also, one would have to do a LOT of shooting to show that, if they shot enough, eventually they would have shots that reached the outermost deviation that SD's would show as possible, whether they were working with +/- 1 SD or +/- 3SD.

Many guys will not shoot a given rifle & ammo combination that much in a year............hence they don't believe it, unless they are statistically astute.

I guess pure mathematics aside, which clearly show a given possibility, doesn't necessarily mean that everyone (or situation) will ever display that behavior......................just depends on how many samples you want to collect to use as data points.

Hey MM, how many on here do you think would go out and shoot say 50-100 rounds in 5 shot groups = 10-20 groups over a chronograph of the exact same load to get an actual SD that’s valid?
If this would happen more and more, they would see the large to small dispersion of group size as noted, unfortunately most on here will shoot 3-5 shots, state they have an SD of 3 then never shoot over the chronograph again unless they think something went wonky.
Also 1500 rounds of the same load isn’t unheard of albeit in my case only 1/10th or 150 rounds was shot over a chronograph.
