having never shot one, i have to wonder, would the little bitty .17 bullet penetrate the skull, or just blow away a lot of skin? i would think that a skull would be different than a grounhogs body...
At 2,500 FPS, at about 60 yards, the .17 hits HARD. I've fired into a range of objects for fun and I'm very sure that a deer skull would present absolutely no problem for it.
