Looking at a .30 or .25

I have a Wildcat in .30 and it is a tack driver at 40 yrds. It has more than enough power to take coons at that distance. I really enjoy the gun and I am sure .30 cal would get the job done. That being said, there is limited ammo options and it uses a lot of air so frequent recharging. 

Ditto on the Wildcat .30. It is my favorite hunting rifle and great for off hand shooting.

I shoot mine from inside my house all the time. I have a "sniper nest" in one of my bedrooms lol. As far as easy to work on that question is subjective... how mechanically inclined are you? I find them pretty easy to work on in general.

There are quite a few .30s and .25s in the classifieds. 

maybe the airforce condor SS in .25 never shot 1, but they seem very quite and more then enough power. im sure somebody here as 1 and can add some real world input. 

You have a sweet gun already. Would be easier to lower your velocity and add an aftermarket LDC but if you are just wanting an excuse to buy a different setup I would choose something in .25 caliber for coons. I say this because it does get tricky shooting at night and you might not get the exact yardage right. Having a flat shooting projectile makes it easier. I headshot this coon at 95 yards Feb 1st. A shot like this made it possible because I was able to count the trees and I know how far apart each tree was. Another suggestion is to have a gun with a mag for quick followup shots. Years ago I went prairie dog hunting in a truck with a disco and it wasn't fun trying to load your next pellet in a bumpy/moving truck.

I just got a Condor SS in .25. Great gun, but not backyard friendly. Even with a DonnyFL, it will stir up every chicken in the coop and kid in the house. It will drop any critter that might bother the coop, but not quietly.

I second wyshadow on this one. Taken a few coons with my .25 cricket out to 60 yards and it has worked great. The cricket is very quiet stock no need for an added ldc. Mine is setup to shoot the 25 gr JSB at 950 and puts out the 34gr JSB at 870, both of which will drop coons or foxes at the distance you describe. I dropped two fox at that distance this past fall within 30 seconds of each other.

I am hearing great things about the uragan .30 or even .25 like 90 shots in the .25 its getting.

I have an Airforce Escape SS in .25 cal. I have it set on and 8 and the sound is quiet. I have taken out foxes at 60 yards without any problems. The Condor is the same rifle just with a larger air tank. I get about 20-25 useable shots and the condor gets around 50-60 I believe. If my memory serves me correct. The FPE on either one is about 60 FPE Maximum. its very light and durable. I love the fact that it is rather inexpensive so I use mine for hunting and I am not worried about getting it wet or a little dirty. Mine survived a house fire. and worked like a charm afterwards. 

My FX Royale 500 is very quiet on its own but with a Donny Ronin it is "mouse fart" quiet. My FX Boss .30 also is very quiet with the Ronin (about as quiet as the Royale without the Ronin) Absolutely back yard friendly. IMO.

One shot a coon two weeks ago with Impact .25 700mm at 60 yards dead right there. My buddy and I have almost 20k pellets thru our Impacts with not one issue. Dont worry about leaks, any gun can leak. Very low noise signature as well. Coon are a tough critter so shot placement is key with any caliber. 

The FX Impact is one fine airgun. The modularity sets it apart from other air rifles in my "herd". Initially, I was in awe of this rifle, however, after owning it (more than one currently) I have become adept at tuning and maintenance. My Impacts are accurate and powerful, depending on the tune.

I've taken coons at 40+ yards with my FX Impact .22 cal.Gen 1. I've also taken them with my FX Wildcat .25 cal at ~30 yards.

Don't allow the reports of problems with the Impact deter you. I think you would be quite pleased owning one.

I take them all the time at 60-80 yards with a .22 caliber at 33ft lbs and a .25 caliber at 46ft lbs.

Recently my .357 is my go to gun at 212ft lbs.

An accurate high 20's ft lb .22 will do nicely and can be quieter.My AT44 has a Neil clauge LDC on it.Homemade depinger and the hammer strike is louder than the discharge.I shoot it in the house alot.

.25 cal bullboss with special baffles it still too loud for inside the house..357 Bulldog....no way I'd shoot it near the house at night.

Both calibers would be very capable at that range. Obviously shot placement will be more important if you go with .25.

I had the same decision to make about a year ago. I ended up going with the .25 FX Impact mk2 700mm. It is quiet, and no leaks or issues. The deciding factor for me was shots per fill since I'm new to this game and didn't have the coin for a compressor.

Here is a shot I took on a nutria rat at 97 yards. They are similar in size to a raccoon.
