Looking for a good accurate but quiet air rifle for hunting squirrel and rabbit

A .22 Walther Terrus is a great airgun for the money with good fiber optic open sights to start out with. It's German made, accurate and powerful enough to humanly kill squirrels. Also not as hold sensitive as some break barrels. Don't know about .177 but .22 would be backyard friendly in your stated environment. It's also an airgun you will not outgrow even if you do get into PCP later. I steered a newbie friend in that direction and he could not be happier hunting (several squirrels taken) and target shooting(accurate). In .22 you will want a pellet in the 14g to 15g range for this AG with H & N 14.66g field target trophy being great but a Crosman Priemier 14.3g from Walmart will work.
I own several higher end springers and shoot my brother's TX regularly. Started with RWS 34, then Beeman R9 then RWS 54 Air King and after shooting a Terrus it is a great price point airgun IMHO.

"StevieRay"Walther Terrus, Airguns Of Arizona (see ad bottom of page) has them for $189 I can do $189 and that is in my budget. Is this a spring break barrel .177 or .22? Are these loud and reliably accurate? Please post the link again on where to get this pellet gun. Is this the gun in the photo with the rabbits? Thanks
It'll be loud, as it is a magnum air rifle and it hasn't got a moderator. But we have one member who has one and loves it. He hunts. 

The Beeman R9 or Weihrauch HW95 can be bought from straightshooters.com (I like them; a small ma 'n pa dealer in Minnesota) pyramydair or any number of other places.

if you can stretch a bit and get the HW95, you will not regret it. It is in a higher class than the Crosman, Benjamin and Gamo springers. Much better trigger, quality and fit & finish. Not to mention a nice Beech wood stock. But they're not all that quiet. Not loud, but not quiet either. Your neighbors will definitely know you're shooting airguns in the back yard if you fire more than once.

Some of the mid level Crosmans are pretty quiet, but you'll need to tune the trigger to shoot them accurately, and they'll never shoot as accurately as the German guns. I have my eye on a Walther LGV, which are VERY quiet, but they're around $700 too.
Would just like to throw this out there, the Terrus is not a Magnum air rifle. It's rated for ~800FPS in .22, I own one, and it is not loud at all (I've not ran any 4.5g gamo ammo through it either though). I did get a Benjamin Maximus this week though, and I have to say I'm impressed. But understandably you're looking at $400 or so by the time you get everything set up, and this is one of the cheapest PCPs on the market. 
 
I agree kmd1984, it's kind of out of the range I was looking to spend. LOL Seriously is there no good air rifles in the $200 range? I have been inactive in my search as I just bought a Parker crossbow for deer hunting. That took a bite out of my spending money so again $200 is pretty much what I am looking to spend right now. There has to be a good air rifle for that amount that is accurate and quiet.

I agree with AirgunMan... I have a Benjamin Trail NP in .22, and I love it. It was a little frustrating during the break in period, but after putting 500 18.13gr JSB Jumbo Exacts through it, it settled down quite nicely. Good groups out to about 30-35 yards. Be prepared to find a good scope that is very resistant to recoil (I am on my third one), and you have to take the time to learn the proper hold for a spring gun. 
 
I have a big box store gamo .177 whisper fusion "1300fps". I purchased it thinking this is the most expensive and claimed to be the quietest one on the shelf to chose from. I live in a development (standard small lots) and have had a bunny explosion (eating my garden and wife's flowers) so that is why I purchased the gun. It was not what I expected what so ever. Loud is a under statement my ruger 22 with subsonic is just as loud and so far I can't get a solid group with a few different pellets. The heavy crossman dome tip seem to be the best and the little blue and red tip pellets are just as loud as my ruger with a standard 22 long rifle round. The crossman pellets get me a 4" group and that is in 10 shot most of the pellets are in 2" group but than you get a crazy flyers. I have managed to get 13 bunnies out the window but it sure cracks loud and one took 5 shots good thing the bunny was stupid and didn't move while I hit everything around it. The factory scope is so cheep the crosshairs don't line up in the vertical so I took it of and used a extra one I had sitting around.

Recenty upgraded to a PCP rifle which my wife is not happy since the accessories are expensive, but I'm happy and since I have to shoot the critters I'm shooting a nice gun that is quite.

Don't want to hijack the OPs thread... so... Consider getting some H&N Baracuda's or Kodiak's those are more appropriate to a heavy springer like the one you bought. Hopefully they will shoot better and also quieter. They won't be as fast but that is a good thing in the long run.

Anyway you have a PCP so have plenty of time to experiment now.
 
Just adding my experience and frustration in the spring gun world and I'm happy for the feed back that will help myself and maybe the original poster when he get frustrated. The guns are pellet sensitive which can be a pain since normal sports stores have very limited stock and selection so you need to order a few different types and it is not that fun to have to order a few hundred to find out they work like poop in the gun. Granted they are not to expensive but you are still wasting money.
 
I can speak to springers mechanisms being louder than the shot itself. But, even at that, my wife cannot hear me shooting from the bedroom window, so it's still fairly covert. If you're outside, yeah you'll hear it - but it's not loud.

What matters a lot is barrel length, and the energy of the power plant. My gun puts a consistent 10ft-lbs of energy into whatever pellet I've got loaded. Longer barrels, higher energy power sources, and price are what it comes down to.

Take a good look at the Air Force Talon and Condor. They look very much worth the price.
