help an average joe shmoe shooter out here....
Isn't it possible for any bullet to get "unlucky", miss the ribs on the flight in, and then fly through nothing but lung... which is like pie meringue?
What tissue is there to even expand on in some cases?
That's exactly what happened with my buck this year - threaded between the ribs on both sides, touching only hide, lungs, and clipped the top of the heart. Mine went 20 yards and was DRT. Shot with a 143 ELD-X from a 6.5 man bun. Entry and exit were about the same size, and bullet wasted most of it's energy in the hill behind the deer.
