its not just about killin stuff man you have to enjoy the hunt for more than just shooting stuff. i was always told dont shoot nothing you aint ready to clean and eat. remember that before you pull the trigger. but as per your question if you can shoot pellets it opens up a little more but really i wouldnt say much with just BBs. if you hit something just right then you can kill very small game but thats about it in my opinionhave B.B. rifle with pump up to 10 times, what kind of small game can i kill using it?
