If you like real long barrels......................................

That’s pretty neat; if I still had a range out back I’d be all over that as a dedicated, “always by the sliding glass back door” piece!

At what point does barrel length stop being beneficial in .22lr?

At a certain point, the friction overcomes the velocity gained, right?

It’s something like 20 inches for .22lr. So yea this will shoot slower than a 20” barrel. I bet it would be very quiet though.

….but look at that sight radius!

I've got an old pre serial Winchester single shot with a barrel that is probably that long. It can hit coke cans all day at around 30-40yds. A fun squirrel gun with no instant follow up shot.

Using cci 22-quiet it makes my springer pellet gun sound like a .22 pistol in comparison. Maybe it's burning up all the powder before the muzzle?

18 to 20" seems to be the magic spot for 22 lr.

The match rifles that Anschutz sells for prone and 3P competition came in factory variants as short as 500mm (19.7"), and as long as 690mm (27.2"). Out to 100m, there is no accuracy difference between the two, only balance is affected. It is not uncommon to then throw a 10" "bloop tube" on the end to extend the sight radius considerably. This is a pretty standard setup for that style of shooting, and when you're trying to eek out sub-mm differences at 50 feet and beyond, it makes a big difference since any aiming error is magnified by the additional length.

I realize this is conventional wisdom, and likely in the right ballpark, but can anyone point me in the direction of somewhere where that has been tested and chronographed over 18 inches?

That's where http://www.ballisticsbytheinch.com/22.html stops and some rounds seem to still be getting increases at 18 inches. I have meant to test this myself for years....but keep forgetting to.

Here is a guy that started with a 48 inch barrel and cut it down in increments. It looks like in this test, with SV ammo, optimal was ~16”.

Saturday Movies: How Velocity Varies with Barrel Length « Daily Bulletin

For most larger centerfire cartridges, increased barrel length augments muzzle velocity. That's why you see F-Open rifles with 30 and even 32 barrels. But there is a limit -- at some point, increased barrel length may not yield any additional velocity. And in the case of rimfire, too much barrel...

Wow, 48 inches! Thank you.

Wish he would have tested more varieties than just standard velocity. What a great, and for most of us, unpossible opportunity, with so much more that could have been learned at minimal extra cost.

My curiosity is in where the highest velocity offerings, Stinger, SuperDuperMaximum and friends peeter out. But the Standard Velocity info is still much appreciated.
 
I’d like to have one of those. Though I’d be afraid it would end up with a Simmons scope on it
 
I had the 455 version of this several years back. It was killer with Tech Sights and really quiet with standard velocity ammo.

This is my 452 UL, basically the same as a 457 Jag. I mounted a 6-24x50 scope and a Sinclair F-class bi-pod. I use it for ARA factory class that I've won matches with.

Bloop tube??

Also - someone made a comment above - does extending the barrel reduce noise? If so, how?
 
I’ve got a 457 22 mag Lux. Love that rifle. Need to shoot it more. I kinda like the Lux length. Although I may try a longer one at some point.

10 seconds after you do an internet search for that term, you’ll know…😉

Yes. More propellant has burned by the time the projectile uncorks at the muzzle. If you’ve ever been around somebody shooting a 7.5” 5.56 compared to a 16” 5.56, it’s extremely obvious. Same theory with a 22LR, but the difference won’t be as extreme when comparing an 18” barrel vs a 27”.

Anyone ever measure the decibel reduction?

(that said, my Winchester 52 with the long bull barrel is very quiet)

It's not super quiet, but when you realize that the difference isn't being made by a can, or a pillow, or whatever your favorite verboten tuber is, but simply a slightly longer barrel, it's pretty significant.

And legit! Not that there is anything wrong with that.

We call it a bloop tube, because that’s the noise it makes when you shoot a .22 with one. It’s a sight extension tube - think of a long, thin-walled flash can with provisions for mounting your front sight. It’s only function is to extend sight radius, though some have barrel tuners built in.

I remember way back 10+ years ago someone on rimfirecentral.com did some testing and determined 16" to be ideal for max velocity but I don't know what ammo was used. Since then I've always considered longer barrel lengths to only be useful for longer sight radius, so if I was planning on running an optic on a 22lr I would stick to carbine length barrels.
