Yesterday I was out squirrel hunting, and one of the squirrels I got had some shot in his back right underneath the skin. I would have to guess it was 7 1/2 shot. Maybe with a better placed shot it could have killed the squirrel, but this squirrel lived to see another day. Until I got him with a .22 headshot that is.

Heres proof that 7 1/2 shot will kill a squirrel.Got him with my Mossberg 500 .410 with 3'' 7 1/2 shot.

I always used #2's on them. It was very effective on getting them out of the oak and hickorys. They weren't full of schrapnel either.
