Funny you should post this. I mainly shoot a bow and I'm planning on seeing if I can take some small game with it this year.
However, I have been thinking of picking up a decent air-rifle too, so I'm interested to see what people say. (I was also hesitant to post up anything about air rifles here, but hey, you took that hit for me lol).
The Vantage isn't it bad. My buddy has one and I've shot it a couple times and he uses it regularly to rid his bird feeders of squirrels and chipmunks.
