longest barrel commercially available .22 rifle
TimR
shooting in areas where the noise might carry.
I saw a hunter in Germany using a long barrelled .22 and .22 short
ammunition to eliminate pest rabbits in an urban area without anyone
noticing. I didn't have enough language skills to ask him about
equipment.
But doing some google I didn't see any .22 rifles longer than 22
inches. What else might be out there? Are long barrels hard to drill
accurately, so there is a practical limit?
Thanks

The Contender G2 Carbine comes with a 23 inch barrel. The CZ452 Lux
has a 23.6 inch barrel. The Encore and Marlin 39A have 24 inch tubes,
as did the Savage Model 24 combination gun. And yes, the longer
barrels are vewy vewy quiet with CCI CB longs...

22 inches is pretty much out there. I think I have one that is 24
inches, an old Stevens 86C. Quietest gun I have. With CB caps, the
loudest sound is the bullet striking the backstop. The only other sound
you hear is the sound of the hammer/firing pin as it strikes the primer.
It's literally quieter than my spring-powered pellet guns, and a lot
more enjoyable to shoot.
CB caps well-placed are good for rabbits or smaller in areas where noise
is an issue.

I don't know about longest but the Romanian M-69 2LR training rifle has
a 23.5" barrel, I thought it was longer but that is the figure given by
http://www.surplusrifle.com/romanian1969/specifications.asp
I know it is pretty quiet shooter.
Some Marlin 39A's have 24" barrel. They are so quiet shooting CB's that
I can't fire it at the range, can't hear the bullet hit the target and
can't see the hole at a reasonable range.
Mossberg made some 26" barrel models search "26" barrel 22LR" also saw
mention of 28" target model rifles, sounded pricey.
The more practical limit is velocity. A 22LR slows down after about
18-20 inches of barrel. If you go too long one starts to worry if the
bullet left the barrel. That is why when shooting the CB's in my rifle I
want to see or hear the bullet strike, as they warn you it might not
clear the barrel in rifles.

Basically, the .22 LR only has a certain amount of space for
propellant and it only produces a certain amount of gas. Velocity
only increases to about 16-18" of barrel length, after that it
literally starts running out of gas. Longer barrels on target guns
are for longer sight radius and balance, not for increased velocity.
Some fellows want longer sight radius, so chop the barrel off to 18"
or so and put on a longer tube for just that purpose, called a bloop
tube. The theory is that the short barrel gets the bullet out that
much faster and any quiver or wiggle on the part of the shooter has
that much less effect. So .22 LR barrels are usually shorter than 24"
because anything longer is wasted metal.
For quiet pest shooting(in the US), you can get any number of high-
power air rifles, their energy rivals .22 Shorts at close range. Many
other countries put a limit on air rifle energies and those are not as
suited to pest control in those locales. On the other hand, firearm
suppressors are usually easier to get there than here. A suitable air
rifle can be had for as little as $100 for a spring gun on up to as
much as you want to pay. A lot of localities will tolerate air guns
that will put you in jail for discharging a .22 Short.
I think who you saw in Germany was a professional game management
fellow, they have special status. Not just anybody can whip out a
rifle and plug pests with impunity over there. Regular hunters have
to go through what amounts to a college course on game management
before being issued a very expensive license. The the jagdmeister
tells them what they can shoot, where and when on their leased hunting
grounds. Anything else is verboten.

and the bullet start to slow down before leaving the muzzle.

One reason for 22 barrels to be no longer than 22 inches or so is that most
22s reach their maximum velocity in barrels from 16 to 20 inches in length.
Any longer and the powder is burnt up and the friction of the bullet and
barrel causes it to slow down. Also shorter barrels are usually stiffer and
are more accurate for that reason.
If you want a quiet shooting gun, get the CB caps. That is just the bullet
propelled by the primer. They will not cycle an automatic action.

Seriously, look at a Gammo Whisper. Had a chance to try one and it was a
lot of fun. Very quiet, 1200 fps and very accurate.

I read this, too. There is definitely a point of diminishing returns when
it comes to barrel length.
Bill Marrs
Theory: Most 22 LR has burned up all it's powder by the time it gets
16"-18" down the tube. Beyond that the barrel is drag, and only
serves to slow the bullet down. So is the long barrel actually slowing
the bullet to sub-sonic? Sound of a normal shot is 2 things. Gas
pressure escaping at the muzle and the bullet breaking the sound
barrier. Long barrel equals low pressure escaping gas, and sub
sonic bullet??

You can also use a .223 Rem primed case. Use a .22 cal pellet held in
the case mouth with a little bullet lube. If the pellet has a skirt,
fill it with bullet lube too. These shoot pretty good out of my NEF
Handi-rifle.

Interesting. I've done the same thing but I used a Lee factory crimper
to close the case mouth enough to hold the pellet. I'll try some Alox

Years ago I tested this commonly held belief by shooting a variety of
22 LR ammunition in a PPK/S 3.35 inch, M41 7 inch, Contender 10 and 16
inch, and a CZ452 23.6 inch. The ammo included standard velocity,
high velocity, CCI Stingers, and Remington Yellowjackets. With all
varieties the longer the barrel the higher the velocity. Don't recall
if I tested CCI CB Longs but wish I had as that is on the case where a
fella can imagine they might start to decelerate in the longest
barrel. Wish I could find my old data, or the post...

I have a mil-surp Romanian training rifle in .22LR with a 24" tube.
Anything longer than about 16" is a waste in that chambering, though, and
velocity is lost to friction in longer barrels. My souped-up 10/22 has a
16" bull barrel and is plenty quiet with CCI brand "CB Longs". Give them a
try. They're a lot cheaper than buying a new rifle! ;-)
Good shooting,

If you use the .22LR SSS Sniper SubSonic 60 grain by Eley Prime
it would be silent in a rifle. In a pistol they bang still but
are not like Blazers or such. The brass looks like a short and
the head is double length.
Some of us used to shoot targets and now are shooting metal or targets
but not hot and heavy any more.

The CZ USA model 452 Lux is a quality bolt action 22LR with a 28"
sporter weight barrel and a 10 round detachable magazine. It's MSRP is
$427. I have one and it's very quiet and reasonably accurate shooting
Aguila SSS 60 gn subsonic ammo.
See it at:
http://www.cz-usa.com
The reason most 22LRs are shorter is that maximum velocity with 22LR
ammo typically occurs with around 16 to 20 inches of barrel length.
After that bore friction usually results in lower velocity. Longer
barrels may be more accurate because of their inertia, and maybe sight
radius. Ballistic performance may be better or worse with higher or
lower velocity near the speed of sound, but rarely good if it's
transonic shortly after leaving the barrel. The bullet and propellant
gas are both subsonic with barrels of 24" or more with the SSS ammo and
are about as loud as typical air rifles.

Could be. If I find one I'll put it through my chrony and see.
That Finnish gunwriter (Pekkonen? something like that) wrote of using
a 32 inch .22 barrel. Though I suppose it could have been a
conversion error from centimeters.
I imagine custom barrels are pricier than I'd be willing to pay. Yes,
I have airguns available, just wanted to explore the rimfire end.
Something like the NEF Handirifle available in various barrel lengths
would be ideal.
Martin H. Eastburn
The bullets don't seat tight and there is some escaping gas.
Match rifles form lead when the bullet is seated. Match bullets
are lubed specially and fit very tight. Sport bullets don't fit tight.
So the science of this and that varies over wide areas.

The extra length may have been a noise suppressor - aka "A
silencer". Getting one of those in the US might be a problem, they're
a restricted item at both the Fed and State level. (In Washington
state, you can own one, but you can't use one.)

I have a Winchester 52 with a 28 inch bull barrel and use a 16 inch
bloop
tube to extend the sight radus. It giges the gun a distinctive bloop
sound
if you were to line this with felt to absorb the sound waves it would
be quite
quiet with sub sonic ammo anything under 1195 fps.
Question is would this now be considerd a silencer and not a
sight extension

Often the match barrels are shorter than 20 inches. What is called a bloop
tube that is added to the end. That is to give a longer sighting radius
when open sights are used.

I'd be reluctant to risk it. I'm not looking for a silencer, just
thinking if I add a .22 rifle, the longest barrel would give me the
quietest "urban hunter" with subsonic ammo and a normal .22 the rest
of the time.
Another thought: they make .22 adaptor inserts for shotguns, and
shotgun tubes are often 30 inches. That'd be a built-in bloop tube, I
guess. Has anybody shot one, and could comment on the noise?

The rifle he spoke of was a Marlin 39 with a 24" barrel. The ammo was
a 22CB. I think CCI still makes them.

It's been done, by American Rifleman at least. However, they may have used
a revolver for the test (for legal reasons, you practically have to use a
pistol -- or something that's legally a pistol -- for barrels under sixteen
inches and it's easy to turn a custom revolver barrel). Something with a
more positive gas seal might produce quite different results.

It's been done, results posted on the net...somewhere.
Perhaps someone has a link?
At any rate, I think the barrel would need a decent crown each time.

It was tested in something I read 40 years ago. Barrel friction is the
reason it starts slowing down. Bullets with a larger powder charge keep
accelerating in the longest barrels apparently, though the rate of
acceleration may start to decrease

I know, a target doesn't take much to punch a hole...
But to have a young teen lug a long bull barrel around and teeter their
bodies just for fun ? I think not. Also, was this a match chamber ?
..22LR is not the same as .22LR Match. Match is tighter.
I can see the change, but not all that much.
And the Olympics have been using long barrels since day one.
So do various like target range / arctic sport. Wonder if bad
science proved that the gun they had did that but that others who knows.....

It's certainly been discussed in American Rifleman:

Velocity and Barrel Length, May, 1977 (Questions and Answers)
Barrel Length and Muzzle Velocity, Davis, June, 1977

Nothing so complicated is needed. An Encore Pro-Hunter 28 inch 22
rimfire barrel will do the trick. Switch from a buttstock to a pistol
grip as you pass 16 inches. Ought to be able to test all the way down
to three inches or so.

# The CZ 452 Ultra Lux has a 28=94 barrel for more precise shooting
I have the 28" CZ Lux. I see no evidence that the long barrel gives
better accuracy than my 24" barrel Anschutz. Why I have it is that with
Aquila SSS 60 grain ammo not only is the bullet subsonic but so is the
propellant gas that follows it. The extra 4" of barrel gives a very
noticeable reduction in noise level relative to the Anschutz with the
same ammo.\

That true of most supersonic 22LR (rifle) ammo. With the SSS ammo the
pressure starts dropping much sooner. Under 6 inches. That's the objective.

I think he meant not *in* the first 16-18". *After* the first 16-18".
And no, the shorter barrel is louder.

My father was chief engineer on the M107 design with a long barrel. Detroit Arsenal decided how long it would be, but he was making money. Long barrel projects just COST ME money.

Nope...the pressure is greatly reduced in the 28" barrel..because it
stopped expanding in the first 16-18"
and as the volume grows (space..not sound)...the pressure starts to
fall off in the next 10 "..and rather dramatically.
I did some review of the subject..and many 22 rounds use the first
11"..

Ayup. So the round is "coasting" the next 16" in a 28" barrel..and the
pressure falls fast!

And 10" closer to your ear ?

My 22" barrel 10/22 is much quieter than my 6" Model 41. It is the difference
between "pop" and "WHAM" on my poor ears.

In Germany RWS used to make .22Z (for Zimmer = indoor use), gad a
lighter .22 bullet, slightly shorter shell and Vo of about 200m/s.
Extremely quiet, but weak.
