The is a bit misleading. That penetration is not the whole.story. There has to be enough impact force.to deter the attack and 10mm on average has double what 9mm.does
While that may be true for just run of the mill ammo for both calibers, it is not the whole story. Here is the real story on the ammo power of the calibers discussed herein: (11) the 9mm is a very weak load, which I call a pea shooter. BUT,, there are a few 'high powered' 9mm rounds, and Buffalo Bore makes one that produces 500 ft. lbs. And in semi-auto handguns (pistols), this may be too much power for most. But, if shooting this high powered 9mm round in a revolver, then there would be no issue. The 'average 9mm round delivers around 350 ft. lbs. (2) The 10mm is noticeably more powerful than the 9mm, with the 'average' load being around 475-500 ft, lbs, and the max at 728 (Grizzly). (3) The .357 Mag (almost exclusively a revolver round and not usable in almost all pistols) is the most powerful of all three of these, far more than the 9mm, and noticeably more than the 10mm. Its 'average' load delivers 600 ft. lbs, and the max round is 907 ft. lbs. (PPU).

If you are considering hunting with any of these calibers, I would not suggest EVER using the 9mm for any animal large, such as deer or bears or cougars. While the 10mm is considered by many to be an effective caliber for bears, I would not recommend this caliber for any game that can kill you, like bears! It may be 'fine' for small black bears, but not the big males, or decent sized sow with cubs. On the other hand, the .357 Mag is powerful enough for most black bears, but you are betting your life on it when big enough and it is attacking you! Nor would I recommend the .357 for grizzlies.

For hunting large male black bears and grizzlies, I recommend stepping up to considerably more powerful calibers, like the .45 Colt (max's out at 1,344 ft. lbs. (Buffalo Bore and only for Ruger and BFR)),, or the famous .44 Mag that max's out at 1,533 (Buffalo Bore). Both of these will have a substantial kick, but usable, and the longer the barrel, the better, thus providing more power and less kick. From there you can step up into really very powerful handguns, all of which are revolvers: 454 Casaul (up to 2,200 ft. lbs, the .460 S&W (up to 2,800 ft. lbs.), and then the .500 S&W (up to 3,000 ft. lbs.). Of course, there are a few in between, but these are the main contenders.

Lastly, there is the relatively new .500 Bushwacker that produces about 4,900 ft; lbs. This gun has a special muzzle break to help with the kick.

If anyone wants my free ballistics file that contains all of this info, including a total of 35 handgun calibers and 25 rifle ones, just text me here with your email address. It is a PDF file.-, and not really usable on smart phones.

I watched the beginning and end of that video last night. I can say that they jammed 20 minutes of info into 1:17 like it was nothing. That guy on the left could talk for 20 minutes and all you'd know is that he saw a young Brown bear approaching him. It was painful. So painful that they made Hickok45 seem like a man of few words, and downright concise LOL

With that said:

I did the math using Buffalo Bore HD ammo only. Forget the 9mm they both chose. It was 10mm vs 44 Mag. You have sixteen 220 gr. bullets of 10mm in a Glock 20 or a S&W M&P. At 635 #'s per round that equates to 10,160 foot pounds. If you have six 340 gr. bullets at 1401 out of a 5.5" Ruger Redhawk you're carrying 8,886 foot pounds of energy.

It boils down to six shots vs 16 shots at a lesser impact per round. You decide.

While it is fun to try to calculate numbers vs. quality, when an animal is coming at you that can kill you at 30-35 MPH, you will never get off more than 4-6 rounds before impact, and more realistically more like 2-4 rounds.. Also, upon impact, the semi-auto pistol will not fire if the gun is pressed up against the body of the animal, but a revolver will always shoot.

Also, do not forget to include the .45 Colt in the high powered revolvers, in addition to the .44 Mag.

Not a grizzly encounter. I put a 180gr Nosler Partition through a Black Bear , then watched about 45 seconds of Tasmanian Devil ensue. Fell over dead 20yds from point of impact.

That experience leads me to believe "dead on their feet", isn't a good solution. I have a 10mm that I can shoot much better than the .41 it has replaced, in the woods protection role. Trauma kit, including tourniquet, resides on the weak side. An indication of my faith in stopping a motivated bear, black or grizzly.

Did you clean and eat it? Just to fly into the ointment, I spend a good amount of the year in bear country. I have found that UDAP bear fogger has worked each time I used it, and has a 25 foot range without wind. No noise, no mess, no 'splainin' to do.

I know somewhere, sometime someone has killed a great cave bear with a pointy stick. That doesn't make it a good idea.

I too have killed a bear. A respectable black bear. It only took one shot from a Remington 700 in 30-06. Bear simply sat down and the fell over.

So based on personal experience the 30/06 is 100% effective on bears with one shot.

Therefore everyone should use a bolt action 30-06 rifle for bear defense.

Heck since you only need one round a Ruger #1 is more than enough.

Heck yes, pretty much the point of me shooting him. As far as my experience with 3 bears they run a very close second to elk, and in some cuts preferable.

I've been dealing with constant bear raids for the last month. I have no feeders up or any reason for them to be tearing my place up....several times they have been on the deck overturning furniture and just knocking stuff around. This has been the worst spring for bear damage. I believe its due to us no longer having a dog as our beloved American Pit Bull Terrier "Buster" passed last year. Almost every night we are awakened by a big Momma Sow (estimated about 300lbs) and four cubs (estimated 180-200lbs) coming over the gate to top deck and knocking stuff around. Yes, I had bird feeders up that they destroyed but nothing now. I didn't even put up the humming bird feeders this year. Learned my lesson. But they are back. My top deck is their playground for whatever reason....lower deck has the grill and smoker...they don't touch it. My wife put up solar powered lighting and they must of thought they were feeders because they tore them down and dismantled them.

Anyway...the first few times they arrived we went to the sliding door of kitchen to top deck, flicked the light on and were face to face with momma sow, who huffed, hissed, popped jaws and charged the sliding glass door and hit it.....stopped and just continued to huff and fog up the window....this being maybe a couple feet with just glass as a barrier. My upstairs/bedroom gun is a G19 w/TLT light stuffed with 124gr Hydrashoks......I'm not comfortable with that at all if these brat bruins decide to crash the door. Wife and I both have 12 GA in our bedside wardrobes....the 1 buck has now been replaced with slug....the G19 has been replaced with my G40 long slide stuffed with Buffalo Bore 180gr Heavy......not really too concerned with them getting in house...but we have guests leaving our place at times and don't want them walking to car and getting near Momma sow and cubs....so I escort them to car with G40 in hand.

I never really let black bears bother me....come across them in the woods often and they high tail it away fast....but this Momma sow that has staked claim here since last fall has given me a bit more perspective after being face to face with her....

Buy or borrow an electric fence charger for a few weeks. Leave the wire in place. Guy can ruin a bait pile with some fuel oil, might try some, be careful though as it'll kill grass even where rain washes it.
