Well the last bit might be a little bit humorous because if you try 10 different powder and bullet combos there goes a barrel before you even finish load development.
Using average anything is problematic. Smooths over variation. I like the idea of standard deviation from point of aim. Put up the article if you find it. Sounds interesting.Quote:

i dont have any personal stake in which is best on this 3 shot vrs 5 or 10 shot groups . . to me its which is more appropriate to what your trying to achieve.
only ever fired one 10 shot group with a centrerfire . . but plenty of 10 - 20 shot groups with rimfires.
use to follow a thread on a US website that started off as a bunch of guys talking about what kind of wildcat to build . . . one was a gunsmith who would build the rifles, they used different actions/barrels/scopes but used the same reamers n bullets . . . these guys were all over the US.
long story short . . . they posted regularly on their progress over months with lots and lots of groups to show how they were getting on, all were 10 shot groups . . . anything less would have proved next to nothing.
but if you own a hunting rifle . . . 2 or 3 shot groups are OK, they're good enough . . . but dont turn up to a meeting of serious shooters with your ' this is the best 3 shot group '
