Cut pistol bullets?

[IronSpike]

Found these cut bullets within a 10' diameter area. Based size I'm guessing pistol/revolver. Why are the bullets cut?

Thanks
I wish I could be of more help on this. It is odd that some are cut side ways. I don't have any idea on that. I guess it's possbil but bullets were taken out of shot game and the cut into pieces at a later time. That's just guessing though. Hoefully someone will have the answer. Right now I'm going to the P.O. then I'm goin' diggin'
