West Central Georgia (Columbus, by Ft. Benning), U
I was curious and wondered if .22 sub-sonic bullets were more, less or equal to .25 pellets in power.

I tested:

10 CCI .22 CB Longs (29 gr), 

10 CCI .22 Quiets (40 gr),

10 JSB .25 Exact King Heavy Diabolo pellets (33.95 gr).



I own (with a stamp, of course) a Q Erector silencer for my Ruger 10/22 and that 10/22 is much quieter than any of my springers and may even be quieter than my .25 Daystate Wolverine R HP – as long as I shoot sub-sonic .22 ammo out of it.



I used my new FX Radar Chrony to collect the data

Of course, none of the ammo weighed what the box claimed. I pulled the .22 bullets from their cases to weigh them.

Five .22 CB Long bullets weighed an average of 30.60 gr, not 29 gr.

Five .22 Quiet bullets weighed an average of 39.53 gr, not 40 gr.

Five JSB .25 Exact King Heavy pellets weighed an average of 33.93 gr, not 33.95 gr.



I shot 10 rounds of each and here’s what I got:

The CB Longs’ avg velocity was 690.60 fps (high, 749: low, 649)

– the FPE of the CB Longs was 32.41 ft-lbs.

The .22 Quiets’ avg velocity was 683 fps (high, 770: low, 643)

– the FPE of the .22 Quiets was 40.96 ft-lbs.

The JSB .25 Exact King Heavys’ avg velocity was 819.17 fps (high, 823: low, 815).

– the FPE the Exact King Heavys was 50.57 ft-lbs.



Hands down, the JSB’s were the most powerful.
 
The JSBs do well at 35 yards, that's as far as I can shoot in my yard. Those CB Longs ain't worth a flip at that distance, but they can hit a 8 inch steel target at 35 yards all day long - but that ain't saying nothing. I have two of those steel spinner targets and the JSBs, can spin them easily - hit the paddle every time, too. The CB Long bullet is not very long, so I'm not surprised that not accurate - they don't often hit the spinner paddle. I haven't tried to shoot the Quiets for accuracy. Their bullet is longer than the CB Long, so I suspect they'd group better.

I think I'll shoot some .22 Qiuets at the spinner tomorrow (one spinner is out at 25 yards and the other is at 35 yards) and see if they can spin it. I suspect they can, if they'll hit it.

BTW, my .22 FX Royale 400, shooting H&N Sport Bsracuda Match 21.39 gr. spin the paddles with authority. And they're very accurate, too. Taken many a squirrel with that combination. That gun, on high power, is producing 32.54 ft-lbs of energy.

Apples do not make good sledgehammers. Why this exercise?

.22 rimfire performance is the antipathy of my interest in airgun.

I told everyone the reason for the exercise, I was just curious about their FPEs. I wasn't trying for accuracy.

Rimfire, air rifle, other firearms (30.06, .45 ACP, 45-70, what ever) - I just like shooting. Plus, it gave me a chance to use my new FX Radar Chrony.

Wins what? High Extreme Spread of the month? Holy crap, how can people shoot those past 20 yards with an ES of 100 FPS? That's at least a 3 inch variance at 100 yards... Unless the winds are howling, my money is on the King Heavies...

20 yards is a long way for these .22 rounds. The JSB's have no problem hitting the bullseye.

Which one wins at 50yd? 75yd? 100 yd or 150yds? Hint -it's NOT the JSB.

Of these three, it probably is the JSB. I'm a wheelchair shooter and I don't have a 50, 75, 100 or 150 yard shot.

This is what I was referring to............POWER (that's why I quoted that section of your post) The 40grain wins at all the other distances and even the 29G passes the JSB at 150.

Sorry, but your JSB Exact King Heavy Diabolo doesn't even come close to winning the low noise battle of FPE between airguns and rimfire, nor in accuracy at long range. Putting the best pellets up against the worst subsonic rimfire rounds is NOT a fair comparison!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Should have put the JSB's up against Aguila Sniper SubSonic, the REAL champion when it comes to hard hitting .22LR subsonic ammo. Firing Aguila SSS out of my CZ 452 I get 900 FPS and 108 FPE. No such thing as a 100+ FPS spread with SSS as a Ruger 77/22 will print 1" 10-shot groups at 50 yards with Aguila SSS all day long. Don't try this with a Ruger 10/22 as I tried it and the round was made for long barrelled bolt guns if you want it to strut it's stuff. Ruger 10/22 has massive gas leak in the chamber due to short case and loose chamber, and massive fouling of the action with continued use. The gas leak means it is NOT quiet at your ear!

Here is why Aguila SSS beats JSB EKH: The Aguila SSS uses a 60-grain bullet, which gives it 50% FPE advantage over JSB EKH at the same velocity. The Aguila SSS needs no suppressor to stay quiet as it was developed for special operations forces using a standard long barrelled bolt rifle as it gets its push in about the first 8" of barrel and then uses the rest of the barrel as the suppressor as the now expended charge expands and cools. A very small amount of powder is used in a very short case. There is absolutely no flash and no high pressure as the bullet exits the barrel. SSS shoots around 900-950 FPS depending on the specific model of bolt rifle. Faster in a 77/22 and slower in a 452 due to slight bore diameter differences. That long bullet has lots of bore drag. The 60-grain bullet will tumble on impact and cause massive damage and expend all its energy into a target of any size except the smallest of animals. A PD gets knocked over like the Hammer of Thor hit it. A suppressor is of no real use with SSS as it is only extra weight and expense. Buy several bricks of SSS with the savings and forget about the suppressor.

Aguila SSS is probably unobtainium right now just like all the other rimfire ammo. There is NO rimfire ammo available of any kind at my local dealers. However, I was smart enough to put away a stash of Aguila SSS a long time ago, and NO, I am not selling any, unless somebody wants to make me an insane offer.

Been using CCI CB Longs for over 35 years now, but never in an autoloader. Mostly in my old Model 52 bolt rifle, sometimes my 77/22 bolt rifle.In the long-barreled 52 they are as quiet as my .22 Impact 700 mm with moderator. They chrono about 660 fps, and I don't have my notes but I don't recall anything like 100 fps ES. More like 30, so I do think the autoloader is relatively leaky. Accuracy is good out to 50 yards, though nothing like my Impact. They hit hard.

Aguila also makes a powderless, primer-powered round. They work in pistols, but the bullet doesn't leave the barrel of the 52.

Yes, the 10/22 is a very leaky loose chambered rifle unless using a tighter match chambered aftermarket barrel. This is likely a contributing factor in the 100 FPS extreme spread of the tested rimfire subsonic ammo.

Wolf Match Target is technically a subsonic round as it shoots at about 1010 FPS out of a CZ 452 American with 91 FPE from the 40-grain bullet. It is made by SK in Germany and about the cheapest true match grade subsonic round I have found. Not too noisy at the muzzle, and by the time it reaches a PD at over 50 yards, it is moving along rather quietly. PD's always focus on the impact of the bullet and not the muzzle report. ES is very low and 1" groups at 100 yards is the norm. I would not waste any money on the other 40-grain subsonic rounds if Wolf Match Target is available. I buy it when I can find it. It works extremely well on PD's as it is the fastest and most consistent of subsonic rounds I have used. It was once available at $50 per brick, but like all other rimfire ammo, it is now unobtainium. That's why the Lonestar .25 will be getting most of the action at PD Town this year.

Food for thought.

I recommend you guys go research Extreme Spreads in Justinamateur's thread called 50 rounds at 200Y over on snipershide. This thread clearly shows what poor ES, which is VERY common in 22rf ammo, and what that does at distance. https://www.snipershide.com/shooting/threads/200-yards-with-rimfire.6928541/

There seems to be mixed results with the SSS 60gr https://www.snipershide.com/shooting/threads/aguila-sss.7064037/

Well there are these posts concerning the SSS 60gr and you'd be surprised at the poor results.

Standard velocity 22rf ammo is usually subsonic but that changes with altitude, temperature, and barrel length, and most standard velocity ammo averages 1050 fps in a rifle give or take a few. 

Sure wind drift is going to favor the highest BC projectile given similar velocities.

HI I have tried them 22 rimfire subsonic and I was totally disappointed with how they shot , they dont group I thought i had a bad batch so I got other bricks of them like cb caps and a bunch of them eleys and again none shot well , accually horrible I could not even hit a soda can at 50 yrds , and with a pellet in any pcp I own I can hit it in same area with every shot ,

I would like to some day get out with my ruger 77/22 bolt action ss 18 inch barrel and put it against my other 22 caliber slug guns and see if it can stay with them , I personally think my taipan veteran , my R5m 22 , my rti prophet , will out shoot it , being they shoot slugs under 1 moa ,

Face it these PCP today came along ways and the 22 rimfire is only as good as commercial ammo is ,



I feel more confident taking out a coyote with my edgun R5m22 then my Ruger 22 rimfire , Now I also have a ruger 77/22Mag , now this one is winner hands down @ 155fpe and ia 22 mag

I have not had as much trouble with Aguila SSS as some other people have had. I haven't had any failures to fire or any extreme spreads in velocity. People with negative results tend to post the most on forums.

I shoot at over 3300 feet above sea level elevation. In my brother-in-laws Ruger 77/22 we shot Aguila SSS at 4400 feet elevation. You do not need as much twist at this elevation as you do at sea level, so 16" twist works for me for where I am.

One thing I did was polish my 452 bore with Remington 40-X after I bought it. I was having some leading issues before that. SSS can have major drag in the barrel so long barrelled guns will have to be clean and smooth. No secret that SSS can shoot faster and often better out of a short barrel, but it will not be as quiet.

As far as Velocitors go, I get 1400 FPS and 174 FPE at the muzzle and MOA at the target. I have yet to hear of any .22/.25 cal PCP rifle/ammo combo beating that performance.

Wolf used to used to be made by Lapua (which makes SK brand .22 ammo), but has been made by Eley the last few years. Wolf Match Plus is a higher grade than Wolf Match Target. Wolf is usually a very good value, but also usually is not quite at the same level as the premium branded stuff. People who shoot rimfire competitively select ammo by lots, and sometimes the lower graded ammo will outshoot the higher graded ammo.
