for what its worth I shot the same squirrel 6 times with a .177 pellet and he got away pretty unharmed. I'd suggest finding a .22 pellet rifle if you dont already have one.

There are several reasons not to use BB's for hunting.

1.Steel BB's are not very efficient for hunting. A standard BB weighs only 5.1 grains and even if your gun was shooting that BB at 1000 fps your FPE ( foot pounds of energy) at the muzzle would be 11.32 fpe.

The standard fpe recommended for small game is 12 fpe. Not to mention that a steel BB does not expand when it hits, it would be like shooting a deer with a field point target arrow. A field point would sure kill a deer if you hit it in the brain or vitals, but not humanely.

2. Accuracy... BB guns are definitely not known for accuracy, this should also factor in to your decision to use it for hunting. If you can hit a quarter ( the size of a squirrels vitals)every other time at 20-30 yds by all means hunt away.

My dad has a gamo that shoots 1000 fps with lead pellets and 1200 with the gamo pba ammo. My mom killed a groundhog with it last year in her garden. Ot is deadly on squirrels. I zeroed it in for them at 25 yards and it shot through 1/4" plywood with the pba ammo.
