there's always an IF try all things being equal and you will see
like me stabbing you with my finger in the stomach as compared to my fist
I might get deeper penetration with the finger but the fist is going to knock you on your butt with less penetration
you want to expend all the bullets energy inside the animal

I prefer two holes, entry and exit, no matter what I shoot a deer with.

I killed a buck today with the Barnes MZ Expander and 90 grains of Blackhorn . What a mess that bullet made on the insides and it was a pass through at about 20 yards .

apologies for the 4 extra posts, nothing happened when I clicked post reply
the forum was in a perpetual loop

Ugh, puleeze. In my 20yrs of online squabbling, not one person who brings up "physics class" or "simple physics" in a discussion of terminal ballistics has had a clue what they were talking about. Sorry but this is more of the same. There is nothing simple about terminal ballistics and if it could be solved by elementary physics, we wouldn't be having this discussion. You're just repeating nonsense that has been handily debunked. There is no such thing as "knockdown power". I'm not going to go into it here but I will provide links to two books that handily dispel the whole notion of energy as a gauge of terminal effectiveness. The second of which has an article I wrote on the .44Mag and .45Colt. So maybe that addresses the comment that I need a physics class to better understand terminal ballistics.

Well Craig I'm not going to argue with you because you refuse to listen or comprehend the laws of dynamics
and that's fine but I'll say this
energy of a bullet formula (one of a couple different ones)
velocity squared divided by 7000 divided by 64.32 x bullet weight in grains = ft.lbs of energy
you'll see there are two factors that will increase the energy weight and velocity
If you increase either then your energy in ft lbs increases
Now would you rather get hit by something traveling at 20 ft per sec or the same object moving a 100 ft per sec?
Energy plays a very important part of hunting and killing an animal
Personally I want to hit him as hard as I can, without penetrating clear through
Because the harder I hit him the more it will shock him and if the bullet stays inside more of a tendency to knock him off his feet if he's off his feet and properly hit in a kill zone he can't run off
I say again you want as much energy from the bullet expended in the animal
the bullet that goes clear through wastes a lot of energy outside the animal
a 170 gr bullet at 1000fps 377. ftlb a 300 gr bulet (many muzzleloads) 666 Ft #
one you want blood loss lots of it two you want hydrostatic shock again lots of it
that's where a large heavy bullet comes into play
the FBI prefers the bullet not to over penetrate for numerous reasons
this being one
Overpenetration is when a bullet passes through its target and out of the other side, risking damaging something or someone else beyond and preventing the bullet from leaving all its energy inside the intended target.

Over-penetration is detrimental to stopping power in regards to energy. This is because a bullet that passes through the target does not transfer all of its energy to the target. Despite decreased tissue damage due to loss of transferred energy on an over-penetrating shot, the resulting exit wound would cause increased blood loss and therefore a decrease in blood pressure in the victim. This effect on both persons and game animals is likely to be incapacitating over the length of the entire shooting event.

but believe what you will

That's good because that's a grade school argument. You clearly have no idea how little understanding you have of terminal ballistics but have already made up your mind. Let me know when you've read those books.

apparently you don't understand terminal ballistics yourself
read this article from Hornady
https://www.hornady.com/team-hornady/ballistic-calculators/ballistic-resources/terminal-ballistics

No where does it say full penetration is desired.
rather you want the bullet to travel fast enough to penetrate the internal organs and to leave a wound channel
but yet slow enough the bullet can transfer it's energy to the surrounding tissue and organs.
Thus a slower moving bullet most likely won't fully penetrate the target and wasting energy after it exits

some more
There are three basic classes of bullets:

• Those designed for maximum accuracy at varying ranges.
• Those designed to maximize damage to a target by penetrating as deeply as possible.
• Those designed to avoid over-penetration of a target, by deforming to control the depth to which the bullet penetrates, which as a by-product, deals more damage inside the wound.

probably more important to have maximum bullet expansion on smaller calibers when you already leaving a large hole from a black powder rifle anyway I would rather have a bullet pass through as it will usually have a better blood trail should you need it.
if your shot placement is good and in the vitals deer usually do not run very far if at all but they may not have to move very far to lose sight of them depending on terrain.
