Figure of Merit and Accuracy

Post by Brent » Mon Nov 18, 2019 10:36 am

Here is an EXCELLENT little video of how the English measured accuracy in their military rifles. This is infinitely better than how we currently do it by measuring group size. If you really want to quantify and compare rifles or loads or techniques (or even shooters), this will be the way to go. ... it-vs-moa/

Brent that is a good way. I look at the average even when I see 4-6" groups at 200. With 2" or 3" that land out the group the average can still be good.
You can still shoot 8's, 9's and 10 and get a couple 7 will still win the match with a average 3 MOA :)

The article on my web site on this includes some illustrations from 19thC plots and description of how figure of merit was determined. See: Measuring Accuracy.

Figure of Merit seems to be fairly widely misunderstood - and with regards to the Whitworth (that sparked the debate/video) there's some vast overstaing of its accuracy appear from time to time in internet chat.
