Until a few weeks ago, I had never considered it. However, a friend of mine shot a small doe. He hit it pretty far back. The doe was 100% perfectly perpendicular to him (broadside). I witnessed the event and we agree.
The bullet was a 70gr 5.56 pressure GMX. Latest production. It entered very punctuate. Bloodshot meat around the entrance extended only 1.5" or so. The inside of the rib cage upon dressing, showed a small neat caliber size entrance with minimal disruption. However, the bullet made its way out of the deer quite near her front arm pit and left significant exit damage. I would say its trajectory deviated from "true" by maybe 8" in as many inches of penetration nearly. By all indications, it failed any expansion and tumbled.
Carbine was 16.1" barrel, deer was about 125 yards out.
Thoughts?
