The issue with getting a DRT on a turkey with non expanding bullets is that the critical vitals are about the size of a tennis ball tucked between the wings plus the spine and head. Most of the body is meat or low density intentistines. They are basically a sack of air below the wings. I have seen or heard of more than a few birds center punched with a high velocity rifle round or a slow cast bullet get airborne and set their wings destined to sail off and die.
