To the 5'rs and 3'rs I say just this. A 5, 10, 18 shot group say more about the consistancy of your AMMO, crosswind conditions, your ability to deal with fatigue and mirage off barrel heat. Shooting for pure precision, my vote is on the 3 shot. Half the time a 5 shot will mangle the POI to shit anyway ('yeah right' they say in unison)
I actually don't understand this opinion. "For pure precision", does this mean you can get smaller groups with a 3 shot group? With this argument why not go for two or one shot groups? Dispose the inaccurate ones and say you have a laser shooter of a rifle.
An accurate rifle will shoot tiny 3 shot groups. Tiny 3 shot groups looked at individually does not mean an accurate rifle.

What is POI? Point of impact?

No I'm not. What on earth gave you that idea? Why do you take it so personally?
My 22-250 has a barrel that has probably done 2000+ shots on it and groups consistently within .8" at 100 m (hunting conditions, no bags), 5 shot group that is. Extrapolate that out and it gives me 2.4"at 300 m in ideal conditions. I bring my maximum sighting range in quite a lot in wind as I'm only shooting 55 gr's. Rabbits have a kill zone of about 4". That would mean it's possible for me to hit rabbits at 400 m but very unlikely. Longest 1 shot kill on rabbits 337 m.
I'd say that is an adequate rifle for purpose, but nothing to write home about. Will chase better accuracy and range when I rebarrel. It shoots great 3 shot groups though hahaha, but I always shoot a couple more and fuck it up 😝

Not personal, quite frankly don't care. Just seemed everyone elses idea of accurate was not good enough
If the rifle is defective you will not be able to make a string of 'tiny 3 shot groups'. So the ability to shoot them does clearly demonstrate the rifle's cold to warm barrelled precision.
*Have a try of this - do a run of 5x 3shot groups and take the average, then again do 3x 5shot groups and take the average.
I reckon there's a good chance you will actually get a higher average with the 3 shot groups as you've had to break your position more often.
Just a working theory - If I remember to do this I'll post up my results (like the wildly flung monkey excrement they may be - just warning everyone in advance)
Only just read bits of this thread, 3 shots is enough for me for my hunting rifles.
Here's a group I shot this morning developing a load for the swede I got off buzzman a couple of weeks back.
I then went out to 400 and put two shots dead centre 2.5" apart, good enough for me. Only 10x scope.
Time to show it a deer.

I don't see this claim being made. If the question is how well a rifle shoots and how far to progress load development, then discussing the means of quantifying this seems reasonable. Samples size follows a diminishing returns curve as a predictor of population, so while I wouldn't myself make use of 18-shot group data IMHO it is a mistake to use 3-shot groups as a predictor of where subsequent shots will impact when 5-6 shots are so much better. As has been pointed out this is more significant for quantifying shot dispersion than for estimating the true point of aim. Load development using 3-shot groups is more likely to lead to incorrect conclusions being made than if Feather or Shoot's advice is taken. This type of thing gets aired on this site quite regularly; pictures posted of a number of groups with requests for interpretation, when all the groups - being 3-shot groups- are statistically the sort of normal variation one would expect from a fixed load.
Bit of an experiment today.
Got a mate over I work with.
He is ex navy but has only fired military weapons and a .22 prior to coming to stay with me.
He is not a hunter or has he ever fired a hunting centerfire.
I needed to fireform some cases so I let him fire 10 rounds at 100 yrds in 50 mins.
His first shot was perfect but he and I were not happy with the next 3 that went left and had a vertical spread.
I adjusted his position as best I could and explained a few principals we all employ.
Either he listened or fluked everything.😆
Not bad at all. 7 rnds 3/4 of an inch once he was sorted.
He put 1, 5, 6, 7, 8, 9 and 10 where they should be.
Pretty sure my rifle is accurate😆
