As I said in my post, all animal don' t always fall within sight, even with solid hits. If they all fell in their tracks, a trail wouldn' t be necessary. I have had lung shot deer to run 100 yrs. The areas I hunt are rugged, not flat midwestern land. I' m only interested in other hunter' s experience with the Barnes bullet. If the Barnes drops all deer in their tracks, I guess I don' t need to look any further.
