Alright, well as promised here are the results of me testing out three different kinds of "quiet" ammo out there.


From left to right: CCI Ammunition 22 Long 29 Grain Lead Round Nose, Aguila Super Colibri Ammunition 22 Long Rifle 20 Grain Lead Solid Point, Aguila SSS Sniper Subsonic Ammunition 22 Long Rifle 60 Grain Lead Round Nose, .40S&W WWB

First, I tested them out of my SIG Mosquito. Results were all three were loud as frick and I should have been wearing hearing protection. oh well.

So, I went and grabbed my 10/22 and the extra barrel length made a whole hell of a lot of difference. Here is the order of quietest to loudest:

1. Aguila Super Colibri Ammunition 22 Long Rifle 20 Grain Lead Solid Point. Very quiet for a .22. The report had kind of a softer air gunny feel to it. Does not cycle my 10/22 action. I could shoot these all day in my back yard without any neighbors noticing.

2. CCI Ammunition 22 Long 29 Grain Lead Round Nose. Not quite as quiet as the Super Colibri but still around the same as a higher powered air gun. The report from this round is a little harder and has more of a little crack to it. Does not cycle my 10/22. These probably wouldn't stir up too much curiosity from the neighbors, but definitely louder than the Super Colibris.

3. Aguila SSS Sniper Subsonic Ammunition 22 Long Rifle 60 Grain Lead Round Nose. By far the loudest. Not as loud as a regular .22LR and no where near as quiet as the Super Colibri. I would stay away from these if quiet .22ing is what you are after. Does not cycle in my 10/22.

Next time I can get to a decent range I will let you guys know how each shoots. But for pest control in my backyard I'll be using the Super Colibris.

Have you tried the Remington Subsonics? I shoot Rems. Wax Coated Lead hollow points.

I was told by a class 3 manufacturer/retailer about problems with Aguila ammo feeding and clearing rifle barrels. FWIW...

A couple weeks ago I'd posted a thread recommending these and love them. They don't cycle in my Marlin but neither do long shots right now.
I think it needs a little cleaning. For what I need it, cycling isn't necessary with the Super Colibri.

Fetched the thread to avoid repeating any shyt.

This made me laugh out load. Nice project though.

I've been away from my machine for awhile, and I was reading some older posts, and I came across this one.

There is an additional option, just in case y'all are interested -- and this is not an attempt to hijack this thread . . .

You may want to consider a bloop tube.

I've seen them in use by competitors in .22 rifle matches.

A bloop tube is an empty, open tube affixed to the end of the rifle barrel; the front sight is mounted on the end of it, and its main purpose is to increase sight radius. Some of them are elaborate enough to allow tuning, in order to reduce barrel vibration to a minimum.

Plain
Elaborate (and VERY expensive)

A secondary effect is that, while it doesn't change the volume, it completely alters the muzzle signature. The best way I can describe it is that it sounds like a very short, hollow, ringing "thump".

It doesn't sound like a firearm at all, and the sound is lower in pitch than an air rifle.

A bloop tube is NOT a silencer, and AFAIK (I haven't checked since the mid 80's), BATFE (formerly BATF) does not consider it to be a Class III device. No FFL required, although INTENT may be an issue.

You could even make a functional, detachable (but ugly) one yourself, from very lightweight aluminum tubing -- the greater the tube diameter, the lower the pitch of the "bloop".

Regular .22 LR match (or plain SV) ammuntion would cycle reliably in an autoloader.

Just my $0.02.

I shot the Aguila Super Colibri yesterday for the first time and was amazed at how quiet they were. No one would ever know that you were shooting a 22 in the backyard with these. I also shot the ones below... I like these better, but they are a little louder. However, they are nothing like a normal supersonic round but they have more power than the Aguila Super Colibri. In my opinion these would be best for getting rid of varment around the house.

ETA- the ammo below does cycle in a 10/22.
