I always go for 5 groups.
The only time I use 3x @ 100yr is with my high pressure magnums like .300RUM, otherwise, always 5x
My trigger is 3lbs max in my hunting rifles so squeezing consistently is not a problem.
 
If a rifle shoots consistent fairly tight three shot groups I'm usually happy. But if it will then group two more very close by I'm even happier.

I'm more concerned that it's shooting where I want it to, i.e. point of aim, rather than how it groups. Groups would be a secondary concern to that.
 
Heavy Barrels get 4x5 round groups and light barrels get 6x3 round groups to get a good group average. However after posting this, it looks like 5x4 round groups for everything might make the most sense.

Concur ... I do a series of one shot groups - maybe 4 or 5 in total, one a day, once or twice a week to verify POI is is as spot on as I can get it. Come opening day, I can pretty much rely on where the first one is going to go from a cold barrel !
 
I have a Win 70 Fwt which won't shoot 5-shot groups; the barrel heats too quickly. It shoots good 3-shotters, though. My Savage 99 and Browning A-Bolt are my only other CF rifles, I'll test them with 3's or 5's depending on my mood and how much of a particular load I built. I think it's more important to have a good consistent 3-shot from a cold barrel....and if you're REALLY lucky, from a cold, FRESHLY CLEANED barrel! How great would that be?
That said, I am a bit more impressed with the 5-shot groups; your rifle can be superfluously accurate, true. But it cannot ever be TOO accurate. I wish I'd never tossed out the target from my best-ever group from my .280 A-Bolt. About 1.5 inches for 10 shots at 200 yards. And truthfully, I'm not much of a shooter.
 
Generally i shoot 3 shot groups with hunting gus, 5 shot groups with smaller calibre rifles I shoot at targets(223) I have had a couple of rifles with pencil barrels that I shot repeated two shot groups that barrel heat would send all screwy if morethan that and they worked great for hunting. The key a a good hunting rifles is predictability of the first and maybe second shot. When developing loads I shoot three shot groups and several of them using average size to determine accuracy.
 
I voted for 5 but in fact that is what I use to develop loads for my Hunting guns but actually when I test them I prefer to fire 3 FAST shots without cooling off to judge their true potential under field rapid fire conditions. For terget work I want the gun to be able to shoot accurately from a hot or cold barrel.

I test the way the rifle is intended to be used.

Initial load work up is done with 2rds. Once I narrow down the accurate load/components, I go to 3rds or whatever the task is.

For a hunting rifle, I hope to never need more then a couple of rds but will test up to a full mag (you just never know). I always confirm a cold fouled barrel first shot hit at all ranges I intend to use the rifle. That to me is way more important then grouping.

For a F class rifle, it better shoot them well after the 25th rds fired under 15minutes.

I also test at the max distance the rifle will be used. Loads at 100 or 200yds may fall apart way out there.

I use 3-shot groups to evaluate a "hunting" rifle for big game. If it takes more than 3 shots, I feel I'm not doing my job right. As for Varmint rifles, I use 5 shot groups, since these I expect consistency from, even when warmed up from a fair bit of shooting. Rimfires get 5 or 10 shot groups. Regards, Eagleye.
 
5 overlapping one-shot groups. Shoot, wait, repeat 4 more times.


Or, for varmint guns, 2-5 shot groups in succession. First group is to see what it does as it heats up, second group show performance when the barrel has reached 'operating temperature.'
