Has anyone tried these for deer? Wonder if they expand? What about for groundhogs and coyotes?

I'm sure they would do just fine.... not quite as reliable expansion as XTP's but they would be fine.... ESPECIALLY for coyotes and other vermin....

Whitetail fine.  Mulies, be sure of your shot placement.

on SQL's note, watch your shot placement with ANY HANDGUN SHOT on an animal!!!
