Can someone figure SD of 5 shots?

In that circumstance you call that 3 shot group and your SD comes way down to 1.4 or if your numbers really suck. Just do 1 shot groups SD will be amazing.

^ the method I prefer! My guns shoot 1 ragged hole 1 shot groups with an SD of 0 and an ES of yep you guessed it 0!

There’s lots of numbers and ways to measure things. Getting repeatable numbers is a journey n stuff.

In reloading terms your SD is 13.349 which means the next bullet has a 90% probability of within 13.34 fps of your average velocity.( IIRC )
