So im curious..(after watchin NuntnFancys Tavor review) If im trying to show the capabilities of a rifle should I show 3 or 5 shot groups?
3 shot or 5 shot groups @ 100yrds?

More shots-per-group is always better.
It is a better illustration of the rifle's consistency.

3 shots if im testing reloads or sighting a scope.
5 or 10 shots to actually check for accuracy.

Let me put this a different way. If you brag about your .5" three shot group, I'm gonna yawn, if you brag about your .5" 5 shot group I'll get interested and ask if you have shot more of those. If you show me your .5" 10 shot group, I'm going to assume your rifle can do that all day if you do your part.

i shoot 5 shot groups and when i say a gun is a moa gun or a 1/2 moa gun its an average of at least 3 5shot groups with that load. Its to easy to shoot a fluke 3 shot group. I dont need to brag on my guns, I need to know how accurate they really are.

Five shot groups at 100 yds is the "gold standard" in my book.....and as "Clutch" mentioned...shoot some ten rd groups for some real proof of performance.

How much time can (does) pass between the first and last shots of the group for those shots to be considered part of the same group? For example, if you shoot one round on the hour every hour until you have ten shots on paper is that one group or ten groups? My point is that you have to consider how that rifle will be used when shooting groups. A 3 shot group from a cold/clean rifle in under 30 seconds would be a good test for a deer hunting rifle. A 10 shot group from an AR308 in under 60 seconds could be a good test for a pig hunting rifle. A 20 shot group in 20 minutes would be a good test for an F-Class rifle. Another thing to consider is where the group is centered. If I had a $ for every small group I've seen that was nowhere near the point of aim I could retire. I've noticed that people are a lot better at shooting small groups than they are at hitting what they're aiming at. A small 3 shot group in the center of the aiming point is a lot more impressive than a small 5 shot group 2" left and 1" low. I've shot far too many of the latter.
One group of 3, 5, or even 10 means nothing to me. Anyone can get lucky once or twice. A series of groups over months is what I'm interested in. Doing it consistently range trip after range trip in varying environmental conditions is what I'm after. Three shots tell me everything I need to know on my hunting rifles. Five different groups of 3 shots tell me more than 3 groups of 5 shots even though it is the same number of shots. In fact a series of 1 shot groups from a cold barrel over the course of a year is more telling. Shooting 5 does not tell you anything about the rifles or loads accuracy that 3 won't tell you.

Do you shoot the group quickly? I tend to shoot the first three rounds in quick succession from a clean/cold bore (possible hunting scenario) and then let the barrel cool enough to shoot two more. The first three rounds represent actual field use and the last two rounds give me greater statistical confidence in the load/rifle.

Given today's ammo situation, I was thinking of going to 1 shot groups.

A display of accuracy is sorta like wine tasting. If you are serving wine, serve it with cheese and fatty meats. The oils that coat the tongue smooth out cheap, bad tasting wine.
If you are buying wine, avoid eating food with grease or oil so you can taste the subtleties in the wine and determine whether the wine is cheap and/or bad tasting.
If you are selling the rifle, its probably easier to impress the buyer with the accuracy by showing a three shot group if your rifle isn't all that accurate. If you're buying the rifle, then shoot more to minimize the chance that a tight group is as a result of luck

Some people will post a, "I shot this one three shot group in 19_ something". I read no further. I agree with an above poster that basically stated he will shoot multiple 5 shot groups for the day and take an average. Now that is method worth doing and a better indication of gun, load, and shooter.

To me it would depend upon the rifles use. If it is a target rifle, 5 or 10 shot groups would be pretty compelling evidence. For my hunting rifles, if they will shoot consistent three shot groups Im a happy camper.

I shoot 4-shot groups for adjusting scopes and sights.
I draw a horizontal line separating the top two holes from the bottom two holes.
Then draw a vertical line separating the right two holes from the left two holes.
The center of the drawn cross is what I consider the middle, and then adjust accordingly.
Everybody is different I guess.

It turns out that if you're trying to characterize your rifle, the average of three five-shot groups is a good compromise between precision and cost.

IMHO, it needs to be at least a 5 round group to be even somewhat significant. I'm painting with a broad brush here, but most of the time, a person may reference a tiny 3 round group they shot and use it to infer that they are an expert marksman, when in fact, everyone knows that the person usually shoots 2-3" groups consistently, but was just lucky that one time.
Yes.
My groups don't always hit right at point of aim, but I can consistently shoot sub 1/4 MOA 1-shot groups all day long, in any conditions, at just about any distance. Make those 2 or 3 shot groups, and the group size opens up considerably!
