Good luck with that. Have recovered cup-and-core bullets from deer when using the .308 Winchester. In fact once recovered a 225-grain .338 Hornady Interlock Spire Point from a whitetail buck that weighed around 150 pounds field-dressed. It was a quartering-away shot at around 200 yards with a .338 Winchester Magnum. Found the bullet under the hide of the far shoulder.
