Walther talon magnum .22 or walther falcon hunter .25?

The Falcon, if you look at the specs on Pyramidair.com, you see that the .25 is only 609 fps with a 17 grain bullet. Thats not enough to kill then, maybe stun but not kill. I would go with the Talon Magnum. I had the Falcon for a little, it was my brothers, I gave it back to him the next day. Its terrible.
