When I started reporting the sounds airguns make, using my new smart phone app that is a sound meter, readers asked me how the sounds of a PCP compare to a .22 long rifle cartridge. The Ataman AP16 pistol that is part of the Godfather’s Gold Gun Giveaway registered 108 decibels on the meter, but a CCI .22 CB Short — a .22 short round with very little powder — registered 112 dB.
Reader Dave said he thought the CCI .22 long rifle Quiet was quieter than his PCP, and he sent me a box to try for you. He actually sent three different low-noise long rifle cartridges and today I will tell you how they all performed.
CCI Quiet on the left, then CCI Quiet Semi-Auto with CCI Subsonic for suppressors on the right.
The first cartridge we look at is the CCI Quiet. It is a .22 long rifle cartridge with a 40-grain lead bullet going out at 710 f.p.s. That is the same velocity as the CCI CB Short with its 29-grain bullet. The CB Short produced 112 dB with the meter three feet to the left of the muzzle. With the meter in the same place for the Quiet the meter registered 105.4 dB
The CCI Quiet produced 105.4 dB from a 24-inch barrel. Sorry for the blur. The camera was hand-held.
CCI Quiet Semi-Auto
We’ll look at the CCI Quiet Semi-Auto next. This cartridge has a 45-grain bullet and goes just a little faster than the standard Quiet round, at 835 f.p.s. A semiautomatic action needs a bigger push to open the bolt, and the standard Quiet round can’t do it reliably.
I tested the discharge of this cartridge in the same Remington Model 33 bolt-action single shot as the rest of the cartridges. This one registered 109.2 dB — just a little louder than the Quiet round. And although I had my electronic hearing protectors on during the testing, I could tell this one was more powerful just by the push it made when it fired.
The Quiet Semi-Auto was louder than the Quiet cartridge, at 109.2 dB. Sorry for the blur.
CCI Subsonic Hollowpoint
The last cartridge I tested was a CCI .22 long rifle Subsonic Hollowpoint. The package indicates it is made for guns with silencers. It puts out a 45-grain lead bullet at 970 f.p.s. at the muzzle. It’s the most powerful of the three cartridges I’m testing and, at 94+ foot-pounds, it’s close to the power of a standard speed .22 long rifle cartridge.
I expected this cartridge to be the loudest of the three and it was, though not by that much. It registered 110.9 dB on the sound meter.
The Subsonic hollowpoint pushed the sound meter to 110.9 dB.
My eyes (and ears) were opened by this little test. All three of these quiet CCI long rifle cartridges made less noise than the CCI CB Short, and the CCI Quiet cartridge was quieter than the Ataman AP 16 pistol! I would not have predicted that.
But quiet sound is nothing without accuracy, so last Friday I went to AirForce Airguns test range and tested all three cartridges for accuracy at 25 yards. I used a Remington model 37 Rangemaster bolt action target rifle for two of the cartridges, and a Ruger 10/22 semiautomatic rifle for the third. Let’s look at each rifle now.
Remington model 37 Rangemaster
The model 37 Rangemaster was Remington’s answer to the Winchester model 52. The rifle weighs about 12+ pounds and the 24-power Redfield target scope mounted on it adds another 2 pounds. The scope parallax adjusts down to 25 yards.
Remington model 37 Rangemaster is a vintage world-class target rifle.
The later model 37s like mine had what Remington referred to as the “Miracle Trigger.” When you squeeze the blade no movement can be felt. The rifle simply fires when enough pressure is applied. There is no overtravel to adjust because the trigger blade has no travel, whatsoever. Some target shooters consider this trigger to be the best they have ever felt. I wouldn’t go that far. It’s just a very good target trigger.
Ruger 10/22 rifle
The 37 is the rifle that shot both the CCI Quiet and the CCI Subsonic Hollowpoint cartridges. Now let’s peek at the Ruger 10/22 rifle.
The 10/22 is a rifle, not a carbine. It has proven to be extremely accurate.
Now we’ll look at the accuracy of all three cartridges. The first two are shot from the Remington and the last one is from the 10/22.
CCI Quiet accuracy
I shot at 25 yards using a 10-meter air rifle target. The rifle was rested in a rifle rest that has adjustable movements in both elevation and windage directions, via long screws.
The first shot with the Quiets landed 3.1 inches below the aim point and slightly to the right. I thought I would have to adjust the scope when I saw it. I didn’t want to hit the 10-ring and destroy my aim point, but I did want to land somewhere inside the bull I aimed at.
I was surprised when shot 2 hit the paper more than an inch and a half higher. Shot three was even higher — just outside the bull I was aiming at, so I decided to shoot a 5-shot group from there. Five Quiet bullets went into 0.527-inches between centers at 25 yards.
The first CCI Quiet hit over three inches low, but by shot three the rifle was grouping on the bull I aimed at. The top 5 shots are in a 0.527-inch group at 25 yards.
In the past this Remington model 37 has put 5 CCI standard speed rounds into 0.375-inches at 50 yards. That should give you a good idea of the rifle’s capability. Naturally one 5-shot group isn’t the final word, but for the sake of this test, I will accept it.
CCI Subsonic Hollowpoint accuracy
Next I shot 5 CCI Subsonic Hollowpoints. The scope was not adjusted. Five bullets went into 0.325-inches at 25 yards. That’s the sort of accuracy I expect from this rifle.
The Remington model 37 put 5 CCI Subsonic Hollowpoints into this 0.325-inch group.
Quiet Semi-Auto accuracy
The last cartridge I tested was the CCI Quiet Semi-Auto. I tested it in a Ruger 10/22 rifle. I own both a 10/22 carbine that is not accurate and the rifle with a 20-inch barrel that is. My rifle is scoped with a vintage steel Weaver V9-IIW, a 3-9 variable with a 32 mm objective lens.
I shot a 5-shot group of the Semi-Auto cartridges at 25 yards and got a 0.535-inch group. That’s okay but nothing special.
Five shots of Quiet Semi-Auto ammo from the 10/22 went into 0.535-inches at 25 yards.
That was when it dawned on me that this scope is variable and I had shot it on 3 power! So I adjusted the power up to 9 and then discovered that the minimum parallax distance is 50 yards. The bull was blurry on 9 power, but I shot another 5-shot group anyway. It measures 0.807-inches between centers at 25 yards. It’s the largest 5-shot group of the test.
Running the scope at 9-power did not help things. The target was blurry and the group is the largest of the test — five shots in 0.807-inches.
What to do? Three power was too low for precision and nine power made the target blurry. I split the difference and went to 6-power. That sharpened the target considerably. This time 5 shots went into 0.499-inches.
Six power proved to be the baby-bear magnification for this scope at 25 yards. Five bullets went into 0.499-inches at 25 yards. The target was sharp and the group is the smallest of the three I fired with this cartridge.
Dave was right about the CCI Quiet. It is quieter than a lot of PCPs. And to my surprise it’s quieter than the CCI CB Short that shoots a 29-grain bullet at the same 710 f.p.s. as the Quiet’s 40-grainer.
It’s not super-accurate — at least not in my Remington 37 target rifle. But it’s about as good as the CB caps I tested for you in 2011. Those were tested in my Winder target rifle that’s chambered for shorts.
Not that any of this ammo is available in the U.S. at this time. They are being made but they are being snapped up as soon as they come to market. You can request the dealer to alert you when a shipment becomes available and that’s about the best you can hope for until things change.
