Curious what this looks like for a 5 shot group that is 1.75”I've done some statistical analysis and simulation of how sample size affects group size, as well as WEZ simulation for various variables.
In the first, I plotted shots fired using Gaussian distributions of shot location on a grid, analyzing average ES group size, mean radius, and mean distance between shots, with 100,000 shots fired for each sample size (e.g., 3-shot groups means 33,333 groups fired, 5-shot groups means 20,000 groups fired, etc.). I made the assumption of ~0.75 MOA on average for 3-shot groups, which I thought was fairly realistic for a decent hunting rifle and load. I have a lot of data and results, and here are a few of them:

As you can see, with large populations of 100,000 shots fired for each sample size, 35- and 50-shot groups average about double the size of 3-shot groups.
And assuming that a rifle/load averages ~0.75 MOA for 3-shot groups and ~1.5 MOA for 50-shot groups, here's a WEZ using a 1 MOA rifle/load at 400 m (with various other parameters and uncertainties):

Have them shoot at 400 and they'll show themselves.Curious what this looks like for a 5 shot group that is 1.75”
Asking as that is what most of my Fudd buddies shoot from their rifles. I would like to show them the hit % at 400 yards. But then again it may show them they have a 70+% chance and would make a poor decision.
