Okay, serious question because I am interested.

9mm is known to be a good/adequate option for self-defense against humans, but it is generally agreed upon that it is not a good choice to hunt whitetail. If you ask hunters, they will say they like .44 magnum, and generally won't complain if you use a 10mm or a hot .357 magnum.

On the street, the general consensus is that there is little advantage to using 10mm.

So my question is, why will a heavy 10mm put a whitetail deer down much better than a 9mm, but on the street there is not a significant difference?

One idea is that deer have stronger bones and their anatomy is such that you are more likely to have to penetrate a major bone of a deer than a human.

Anyways, just to be clear I do see that the 9mm does do the job for self-defense against humans, we have lots of street data ... I am just confused because deer seem to have the same size body/bones yet the general consensus from experienced hunters is it is too small. If you mention you will be hunting a deer with 10mm or .44 mag Buffalo Bore ammo none of the other hunters seem to tell you that you are using an unethical weapon.

Thanks!

Just because hunters generally agree on calibers doesn't mean anything. 
9mm can absolutely kill a whitetail in one hit. Shot placement and range are the 2 most important factors, assuming your lead delivery system and ammo are G2G.

Most "hunters" around here seem to think you need at least .30-06 M2 AP to kill grizzly bears.

I have seen deer hit in the heart and you would have thought it just dropped but it ran 200 yards
because he didn't know he was supposed to die so it ran until it did. most humans would panic
and go into shock and die because they just know whats going on.

Well, I suppose what I want the bullet to do is to penetrate through the vitals from any reasonable angle. A complete pass through would be best, but if not, I'd want the bullet to go well past halfway through the animal. So I would need the bullet to do that even if it hit the strongest shoulder/leg bone before passing through the vitals.

I'd guess 150gr hardcast would do that ... but will a Gold Dot or HST do that? I don't know ... do you think it would?

Well with animals you want to kill it with one shot. Don't want it to run off and take forever to die, it's unethical. With people, if you shoot them and they run off, they go to a hospital. So using weaker calibers for self defense works fine. But it's better to use larger calibers for hunting to ensure that clean one shot kill. I personally carry a Glock 20 10mm for self defense and walking the woods, works great for both roles. I mean you can kill people and animals with 22's given the right shot placement. But rifles like a 308 or something are much more preferable for both humans and animals. We make compromises when carrying a handgun. Less power for more convenience.  9mm gives you more ammo capacity and faster follow up shots, and most people can conceal carry a 9mm handgun. Is a 6 shot 44 magnum revolver better, it's way more powerful, but has more recoil and less rounds. Under stress you might miss and want those extra bullets. So 9mm makes more sense for self defense and 44 magnum makes more sense for hunting.

Carrying a handgun is a compromise between size and power.

Theoretically handguns are carried when rifles can't be. So a 9mm is big enough to kill someone and small enough to carry but doesn't reliably
Kill a 200 pound person/animal in one shot.

So there's no reason to compromise when hunting on size and power.


Just my thoughts on it.

I'm going with penetration. Certain angles on a deer require more penetration and when hunting you want complete penetration.

For self defense, "over penetration" is seen as a negative as people generally want the bullet to stay in their target.

I personally don't think overpenetration is a negative though.

Usually the argument about 9mm over 10mm deals with ccw situations. Typically you want the shortest lightest ccw that has an adequate barrel length and capacity to just get the job done. If you feel more comfortable carrying a pistol with a 3" barrel all day everyday 9 is a more reasonable answer. Your not losing much in ballistics. The 10mmer's, and magnum pistol rounds work better out of longer barrels and have very little gain in sub compact form, it's not worth the trade in capacity. Also deer don't have lawyers attached to them, unless maybe your not in season.

I think it's range and accuracy.  A self defense designed 9mm handgun with a ~3-inch barrel is sufficient for self defense because the ranges for most self defense scenarios are short range (less than 10 yards) and you are going to shoot until the threat stops.  With deer hunting the ranges are usually longer and the target more agile so follow up shots are much harder.

That said I would think 9mm with heavy (ie ~147 gr and similar) quality bullet from a long barreled 9mm say >=5-inch handgun with quality sights or optics would be just fine for deer hunting assuming the hunter can hit with their chosen handgun and ammo combination.  It would certainly be on the bottom side of what is acceptable IMO (though not legal in many states) and thus would require the hunter to make sure they can put that bullet right where it is needed since the 9mm has no extra energy to make of for poor shot placement.

The lightest cartridges I have personally hunted with so far has been 410 slugs and 10mm Auto.  410 slugs worked fine but a shotgun  (with decent sights) it is easier to shoot accurately than a 9mm handgun and 410 slugs still has significantly more energy than 9mm.  I did take two deer with a 10mm revolver last year.  It worked fine too.  This year its overkill year with a 450 Bushmaster.

I have shot several with 9mm works fine.
A good 147 gr flat point does good on small hogs.

-9mm is a compromise for handguns. No need to compromise when hunting.
-9mm IS plenty powerful to take a deer, but not efficiently
-A more powerful round makes a more ethical hunt
-2 legged predators have "OFIBS" (oh f*^% I've been shot) psychological factor... Deer don't

Any round capable of penetration to a heart, brain etc. can kill a deer with one shot. That includes a .22lr with perfect shot placement.
Perfect shot placement can not be relied upon so larger calibers are more reliable at making bigger holes than their bullet diameter and more penetration due to velocity.
A human gets shot and is (hurt) and paralyzed by a shot even if it does not hit anything major, in theory. A deer gets shot and runs till they die, the pain and paralysis is not really existent or at least not as recognizable in a wild animal like it is in a human.
An animal will run away till their body gives out while a human runs till their brain tells them their body has given out. Big difference!
The only way to be sure to drop a deer with one shot is to actually kill it and bigger, deeper holes are more likely to do that.

9mm from a handgun does not meet my states rules for hunting with a handgun (they have an energy threshold you must meet). But, it's legal to hunt with a 9mm rifle, as long as it is a "centerfire cartridge firing expanding bullets"... I can shoot the same cartridge from two types of guns. One would be legal, the other would not. Silliness.

This also means I am legal to hunt bison with a .218 Bee or .22 Hornet... the law, as written, sucks. I could probably hit their energy threshold if I was willing to load up to "9mm Major" velocities. 9BPLE is almost there.

I have personnaly seen a buck take a 300wm through a shoulder, lung, blow the heart to shreads and exit leaving a baseball size hole run untill it bleeds out then run another 200 yards through the thickest texas bush.

We only found it due to the damage the animal did to the ground everytime it fell, then got up and ran some more.

Whitetail deer are have weetard strength and desire to live.
Sure we all have that grandpappy or uncle who only hunted with a 22 and one shot dropped everything he zapped. But reality is bigger the damn bullet the better when it comes to wild animals.

People often mistake hunting and self defense in regards to both animals and people. They also underestimate how tough animals are compared to people.

If deer were dangerous and attacked people nobody would be carrying the calibers they do they would all pick bigger badder stuff. Getting to sneak up and take a well placed shot(ideally) is different than being surprised and having to stop the threat immediately.

Just like if I knew I had people coming after me there’s no way the only gun I had would be a 9mm. It would be a rifle but that’s just not practical. Even a pistol caliber carbine would be a step up over a standard pistol.

9mm 40 and even 380 pistols are the most popular choices because they fill the need of being concealable and still somewhat effective. Nothing more nothing less.

It is unethical to make a dumb animal suffer needlessly when hunting.  Put it down cleanly or go home.

When you have to defend yourself from a scumbag human who is intent on robbing/raping/killing you, it is not considered unethical to make him suffer.  Go ahead, let him suffer.  Wallow in it.

ETA:  Today's society considers it more ethical to wound a bad guy, making him suffer, than to kill him.

Different goals. Hunters want ethical, fast kills from a single bullet.  The primary purpose of a handgun for self defense is to stop an attacker while balancing size and weight so you can actually carry it. Doesn't have to kill I'm off shot, just has to stop them before they bring you harm.

Pretty much this.  

Handguns for self defense are a compromise.  You are carrying a tool to protect yourself, not harvest food.

When hunting you are not just running to the store to buy groceries.  You have more options for the size and power of the weapon you carry to do the job at hand.

Also, in a self defense situation the ranges are very short.  7yds or less on average.

When hunting your range can vary anywhere from point blank to several hundred yards.

Then there is the whole point of carrying for self defense vs hunting.  Your intent is not to kill when carrying for self defense.  Just stop the threat.

When hunting you are trying to kill as fast as possible to avoid the animal getting away or dying a slow painful death.

Here's a hunters point of view.

We care more about humanely taking game than we do about humanely taking a miscreant.  I feel bad if I cause an animal I'm taking to endure pain unnecessarily.  So, I'm going to use a cartridge that has a good potential to kill the animal quickly and cleanly.

People, I don't care so much.

If I were stranded & hungry, and a 9mm handgun was all I had, I'd use it.  But if I'm going hunting I'm reaching into the safe and get a rifle with enough accuracy and power to do the job quick and clean.

What about from a carbine?  9mm gain velocity from the longer barrel and the ability to shoot them accurately with longer sight radius or better optics improves greatly.  Assuming your using a quality bullet that can handle the higher velocities I would think this would be interesting.

Thank you everyone for the informative answers. Here is what I learned:

1. Due to their anatomy, deer vitals are generally several inches deeper in their body than humans' vitals are.

2. Deer are hard to kill and run like an athetic man on crack when shot. Humans usually have a psychological response (as well as vitals not being as deep usually) so less penetration is required.

3. If you have a good broadside shot, a good 9mm bullet will penetrate a deer's vitals enough for a kill

4. Recoil, capacity and concealability/convenience are part of why 9mm is the 'default' caliber for conceal carry.


Thanks!

A 9mm in a hollow point will penetrate about the same as a 10mm or a .357 Magnum in a hollow point. 12 to 18 inches. In a hard cast flat point, no matter what the weight, they'll both penetrate both sides.

The reason hunters say different is the same reason hunters say a .223 is a pea shooter and inadequate for deer and you need a .308 or 30.06 and the same reason people think a .45 ACP will spin you like a top and knock you down in one shot.

Shot placement is everything. A .308 to a deer's ass is worse than a 9mm to deer's vitals.

Based on gel tests I have seen, a 180-200gr 10mm or a 158gr bonded .357 penetrates more than a 9mm in general. They penetrate around 18-20in vs 14-15in. I also think they are more likely to break bones with the extra momentum... not that thise are 12ga slugs or anything.

But after reading all the respons3s a good 9mm does seem to penetrate enough.
