I bought a brick of Remington Subsonic this morning. I don't have any experience with it. How quiet is it? Will it wake up the neighbors?

Unless you use a suppressor you likely won't notice a huge difference. Subsonic means it doesn't break the sound barrier (1128 +/- fps). When you shoot the sound you actually hear comes from several sources (muzzle blast, bullet cracking through sound barrier and gun action -- bolt, etc.). A suppressor takes care of the muzzle blast and the subsonic ammo takes care of the sonic noise - nothing really takes care of the gun action noise)....

In simple terms......

How far away are your neighbors? It doesn't have the supersonic crack of standard ammo, but it's not silent, either.

I'm not sure how load it is out of a 15-22, but when I use Rem Subsonic in my marlin lever action rifle, it is quieter than an pellet gun.

Thanks for response guys. The neighbors are like a block over. Not very far. I wasn't expecting it to be supressor quiet anyway. Thought maybe I could do some backyard plinking without getting the police called.

Is discharging a firearm legal where you live? Many cities have ordinances forbidding this.

Yeah it's legal to discharge firearms in what are considered "county" areas, but not in "city" areas. But I don't live in the country where there is no one around for miles.

I've tried Rem Subsonic with my 15-22 and suppressor. A great many go supersonic or fail to cycle the action when staying subsonic. If you are looking for reliable ammo that is accurate and will stay subsonic I would recommend CCI Standard Velocity or Subsonic. Aguila 60 SSS is quiet and reliable in my 15-22 (I don't use it for suppressed shooting) and good for small game. It is pricey.

I shot 100 rounds of that Monday. about the same as a standard load. cycled good though. no ftf or fte.

I'll keep that in mind Phil. I wasn't looking for subsonic ammo, but Walmart had a couple of bricks in stock so I figured what the heck. I've only had the rifle since January so I buy ammo when I see it (right now I have RWS, Lapua, CCI Blazer, Rem. Golden Bullet, and Win. 555 and M.22). It shoots it all. I'll definitely pick up some CCI Sub and Aguila 60 SSS if I see it.

Bamabred, I'm glad you asked this question.

My wife brought home a box of the same stuff, and we wondered if there was any reduction in noise.

It's about the same as a duck farting in deep water. No, but really its noticeably quieter than regular ammo.

have you shot the lapua? I bought about 200 rounds of it, the target trainer rounds. I have not had good luck with it. won't chamber all the way, even with a clean chamber and bolt. wouldn't fire a single round, even on my dad's semi auto browning hand gun. he had to actually push the bolt forward to get them to chamber fully. seems really waxy to me.

Those are the only ones I haven't shot yet. Mine are the match grade ones. But they are not waxy like I hear so many people say they are. They do have slight oily coating on them it seems, but it's not dramatic. I hope it does well because I have 250 rds of it.

I have had good results from the Win. 40 gr. HP sub-sonics,,,, quiet without the can,, whisper quiet with. I also have some of the Rem. and CCI sub sonic that I have not shot yet,,, after such good results from the Win...... Not trying to confuse,, just saying,,,,,

So they do cycle well, Ive heard back and forth about it not able to cycle and is just for BAR's only. I'm more then glad then cause I can get a box of subsonic 50's for 10 which Ill take. Better then 18 for 50, plus would like to have the ear muffs off when Im alone, the electric ones like to pick up cell reception... Scares ya when it randomly goes off.

Zeroed the night vision on 15-22 2 night ago, light snow, full moon, 3 am, with rem subs, Liberty Kodiac TL can and the wife did not know even though I was shooting right below the bedroom window. "Silent Night"

Oh yes! You will wake the neighbors. If you are looking for quiet you should look at Aguilar .22 Super Colibri. When I shoot them all I can hear is the striker fall and the bullet hit the target. They are not terribly accurate but are great for pest control and will scarcely penetrate a fence board. I wouldn't recommend your trying to shoot them in your 15-22 though. I use an old Winchester mod 67. My RWS 52 pellet rifle is much louder.

If you want quite, try the CCI CB's, there are about as loud as a pellet rifle.

Not to sound like a complete newbie (although I am), but the owner's manual suggest you not to fire any sub-sonic ammo in the 15-22. But, I see lots of people still do. Is it safe for the rifle? No harm intended, just curious.

I'm a newbie myself, but I think it has something to do with twist rate and bullet stabilization. Also, some of the subsonic stuff that won't cycle can be dangerous if a round gets lodged in a barrel. I could be wrong

Not gonna get lodged in the barrel. There is very little difference in velocity between subsonic rounds & standard rounds. For example, CCI subsonic goes at 1050 feet per second while the CCI mini-mag is at 1260 fps. At that speed, all will get down the barrel with no problem. Only difference is the subsonic will not break the sound barrier & you will not hear that crack. But keep in mind these velocities are nothing like a true AR shooting .223, which moves at over 3000 fps. IMO, you only see a real difference between higher velocity 22lr & subsonic is when shooting suppressed. Only then would you really notice the sonic crack.

The 22 bullet is an old design & not really aerodynamically sound. When it goes thru the sound barrier it is buffeted, not unlike the early jets that attempted to break it. It also gets bounced around when it slows back down. That is why almost all match ammo, where accuracy really counts, is subsonic. CCI's best target ammo, Green Label, is their normal standard velocity (which also is subsonic) but just is the cream of the production run & QC checked closer.

Look I'm a printer & not a scientist, but this is what I understand & have learned around here & on the internet. I will be shooting suppressed soon as my stamp comes in & I have a nice stock of CCI subsonic & standard velocity/green label ammo. All 3 shoot great in my 15/22 & I have never had any cycling issues or any failures at all. Plus, when the suppressor is added, back pressure will increase & help even more.

Though the CB's or CB longs are pretty quiet thare is still a crack. The issue with some subsonics in autos is that they are a pain to shoot because they may cause feed issues. This is especially true with the 15-22 with the charging handle and the protruding ejector. Shooting the 15-22 is great fun but it's versility is limited by the ammo it will digest without issues.
