I wouldn't want to gut shoot a deer, due to the mess. But If it was the big one walking away, I probably would.
Its about knowing versus guessing.
People get off on "modern" bullets to the point that somehow ANYTHING but a broadside, double lung shot is the only certain, ethical shot.
Oddly enough, the bullet I made did exactly what I poured it to do. If viewed from someone who routinely shoots deer with a 270 and a 150 Ballistic Tip, yeah, its going to be messy and might not always work out so well.
A gut shot? Nope. Exited exactly where I knew it would. Instant kill.
"Gut shots" dont work out that way.YMMV.
