What PCP to choose

Hi, im in the beginning with PCP air rifles .I've shoot rabbits with my friend`s FX and I liked this type of air rifles .My question is: What PCP rifle to choose for 800-900$ budget.
My requirements are:
1-To be accurate
2-To be enough powerful to kill rabbits , pigeons , crows ,magpies and pheasants on 160-190 yards.
3-My favorite calibers are: .22 and .25

I saw the Walther Maximathor .22 and I don`t know is this rifle meets my requirements.

Thanks in advance for the tips !!!
 
160 to 190 yards? You’re gonna need a top-tier air gun. And do a lot of testing and tuning probably. So like was already mentioned, a used air gun would be the way to go for that price range.

This. Gona need alot of power to push out thay far. And a damn good barrel +tune +projectiles to boot. There isn't a uivversal recipe. Or one gun that can be guaranteed to shoot well enough that far out. But there are a few that can be made to. Any of the fx's that have large plenums. Or a 257 texan with a real nice barrel/slug pairing 
 
Buy an RWS model 54 or 56 for shooting 160-190 yards and a good scope and UTG droop compensating mounts. 

If you can find an FX Tarantula long gun or Career II 707 long gun or Sumatra long gun or Air Force Condor 257 or Texan in any caliber those would do.

The FX Impacts have to be tuned absolute perfect and you have to make your own slugs to do it reliably.
 
So, I don't want to be a kill-joy, but, do you have a fill system and scope? That might cut a major portion of your budget. Please take that into consideration. Long range shooting does require special rings for the scope, so cheapies won't do the trick. Figure on $70 to $100 for adjustable rings alone.

Now, to be a double kill-joy, I think you can forget the 160 to 190 yards with accuracy in the sub-$1000 arena. Probably need to move up to guns proven at long range which means a bigger budget.

The Extreme Bench rest was Extreme at 100 yards for a reason. 99% of air rifles just aren't that accurate at ranges of 100+ yards, so nearly doubling that does require a better gun. Perhaps a Crown or new Maverick? Both are double your budget but proven at ranges you speak of.
