I have killed lots of animals with my .25 Marauder.
Used a scuba tank to air it up mostly.
If you have trouble with accuracy, try different pellets... they will shoot some well, and some awesome, and a few pellets don't shoot well at all.
It's a 50 yard rifle for the stuff I shoot. Maybe further, depending on the game. But if you put it in their ear, they fall right there.
