Longer sight radius means more precision in aiming.
That’s practical accuracy using iron sights and has nothing to do with intrinsic accuracy.

When you get deep into benchrest, you will find that shooters have discovered that it pays to have the bullet exit the muzzle at a certain point in its rotationCan you share a cite for that? I'm intrigued.
It's at a certain vibration point, which is how barrel "tuners" work.I don't remember, it's been a while since I read about that. Might've been one of the benchrest forums but that sort of thing doesn't interest me.
Ok, keeping with 22lr here, is there any consensus on what barrel length on average is most accurate? Not talking about sight radius, bedded stocks, better triggers, just barrels.
And yet some, like myself, prefer a longer barrel. IMHO, this isn't a decision to be made solely based on a data sheet.
For iron sight shooters longer barrels usually means longer sight radius and thus better aiming so all else being equal means better shooting.
For optics, at distances where the velocity differences don't make a tremendous differences the shorter barrels can be "more accurate" because they are generally "stiffer" and thus should have more favorable "barrel harmonics".
While barrel length is important for precision with irons, lots of service rifle National Championships have been won with AR15's and their 20 inch barrels.
Good observation.Open the field a bit, consider Match Rifles - while it might have happened, it’s a purty rare day when a 20” A2 bests a 29” Match Rifle
In fairness, Service Rifle matches don’t allow longer than 20” AR’s, and the irons are required to be of standard A2-A3 type, and in the standard position.
So this is basically saying competitions among 20” AR’s are won by 20” AR’s.

About .22s.....what will you see if you walk the line at a smallbore championship - either day, iron sights or any sights - mostly long barrels (forget the bloop tube) or mostly short? (How many short barreled prone rifles does Anschutz make?) What are the winners shooting?
There are lots of short barreled Anschutz rifles on the firing line. They did not come that way from the factory. Shooters buy a premium, aftermarket barrel, and pay someone to install the thing. Accuracy wise, an Anschutz barrel is just fine, but, shooters follow the herd.How many short barreled prone rifles does Anschutz make?)
I bought a Ruger Charger recently and it has a 10 inch barrel. In talks with someone about .22 accuracy and barrel lengths, there's a guy at his range that exclusively shoots .22 LR in matches and using high end rifles with 24 inch barrels and has been for decades. The person I spoke to asked this .22 shooter at his range what affect that barrel length has on .22 accuracy and the reply was something to the effect that the longer barrel burns the powder more completely, but doesn't necessarily add to the velocity with subsonic standard velocity .22 ammo because it is in fact so long, but that complete powder burn makes it more accurate.
