My point exactly, thanks for clearing that up.
Had you been using a 175 grain bullet at a more appropriate speed you would have had total penetration.
I'm actually not so sure on that. It's hard to armchair this one. 150 gr. at 3000 fps...that's an impact velocity around 2600 fps - I'm quite willing to argue that was a very appropriate impact velocity. A 175 would have impacted at around 2300 fps (muzzle velocity for my rifle clocked 2700 fps). I doubt the e-Tip would have over expanded...and certainly a partition would have shed the whole front of the bullet on that impact leaving a base of around 140gr to penetrate forward vs. the 148 gr. of the e-Tip (figure 2gr for the plastic tip).
A 175 TSX might have done better, particularly if the petals blew off. That's quite possibly true.
So I am willing to say maybe...but it's still a crap shoot. Hitting that big shoulder muscle, then bone (about as thick as my forearm) and then going through ribs...and then deep into the lungs, that's still serious penetration. The Zebra I hit busted two ribs on the near side, one on the far side and the shoulder bone, stopping under the skin on the far size. Some 30" of penetration there.
Any way I look at it, it's still a very serious penetration test.
Going back to 2011, I used a 300 H&H with 180 TSX's at 2900 fps. I'm not sure it would have done any better based on the penetration tests I had on a Kudu. The first Kudu took three shots to bring down with the first shot breaking ribs and a shoulder. Damn thing ran for nearly 700 yards, sucking up two more rounds in the process. The second kudu took a perfect shot through the ribs/heart/lungs exiting at 300 yards. It fell over 20 yards later.
/shrug. In the end, it's hunting. Stuff happens. In my perfect world, a .375 H&H would have been a better choice but I didn't have that with me at the time.
All I want is for people to go out and have a great time on safari.
PS: Army, I was pretty sure I understood what you were saying.
