Skitch,

My eight year old son shoots a gamo640 (640 fps). He's taken several squirrels with well placed shots, but he's also lost several. For small game hunting, you really need 1000 fps or more. My 11 year old shoots a gamo 220 (1000fps) and has taken squirrels, possum, and coons. Not to mention a few crows. The 640fps air rifle could never take a coon. In addition to following state game laws, make sure your town does not have an ordinance against airguns. You can call the local police or sherrif department.
