Hrmm.... that's interesting you say that "..and don't ruin a ton of meat beyond the area of the penetration" I shot a 168gr Barnes TTSX .308 Win into my first deer at 40yds. There was like maybe a 5-inch circle of bloodshoot meat around the entry wound. The shot was a little high and back. I'm pretty sure it came in just under the spine, and that the shockwave took out the connection to the rear legs. The animal got knocked like 10 inches sideways... dropped to the ground, then kicked around with just the front legs for a while, before expiring. (I did gutless method on that one, so didn't inspect inside the animal.)
Then the next year... Federal Trophy Copper .30-30 150 grain w/ Roundnose Polymer Tip.
It was extremely hot that day so decide to gut the deer to ensure meat got cooled as much as possible.
A very angled-in shot that entered at midline of body just behind ribcage. Punched a Silver-Dollar sized hole thru the liver, completed decimated the right-hand side lung... did not exit... lodge just under the opposite scapula (shoulder-blade). Recovered that bullet and textbook mushroom. Though it did not exit, the damage was impressive considering how long of a path it took thru his body. Would you believe?... No immediate reaction to the shot! No kick up or anything like that. (Although he *was* mid-trot crossing an opening and going away from me as he noticed me raising my rifle) That mofo ran like 20yds before he finally started to lift up that opposite leg while running and continued to run out of sight for another 40yds! Was so weird how he didn't do anything to immediately indicate he'd been shot though! For a few milliseconds I was freaking, thinking to myself "No! No Way! What the Hell? There's No Way I missed that shot!" (Was only 25yds, so no way I missed it) As he ran away at first when he turned to run directly away from me and I could look down along his body and finally see the other side, I noted I saw no blood/exit wound... which further freaked me out and made me momentarily think I'd somehow missed!... but then once he started not letting that opposite foot touch the ground I was like "Phew! Ok... Yes!"
