There is no possibly killing a whitetail deer..it was hit and died with # 4, you know the chitt you said would splat on your skull. I would think a deer would withstand a buckshot load a whole lot better then a human. .
By possibly, I mean they won't kill you if they run away. I've seen lots of stuff shot with #4 buck, including a couple of exceptionally thick skulled democrats it didn't stop that 00's would have. I've also seen many killed with a load of #6's from a .410. I reckon it just depends how many times you want to shoot 'em and how far it is okay for them to run.
