Ballistician Bryan Litz posted an interesting dialogue on dispersion on Facebook.

In a nutshell…he proposes that if you shoot 20 5 shot groups, your largest group will be approximately 4x your smallest group and your average will be about 2.5x your smallest.
That is pretty close to what I’m seeing in this 20 group sampling at 50y. My smallest to largest is about 3.5x. This could mean that over a greater sample size I might get a slightly smaller average “small” group or a larger average “big” group.
Pretty interesting….If you read the whole dialogue.
