10mm vs .357 Magnum for Bear Protection in Alaska

[@RadDadisRad]

Underwood hasn’t spiked their ammo prices during the ammogeddon. Supporting them only seems right since they are doing such a good job keeping stock and reasonable prices.

[@Hudge76]

When I moved to AK over 8 years ago, I was told to buy a 357 Mag and file the front sight down for bear protection. When I asked why file the front sight down, I was told it was so I could get the barrel in my mouth easier for when the bear mauls me.

That's a nicer way to put it than what I heard

Well Boys. I guess to be sure better pack the Alaskan 454 Casull. Stub nose.

[@ralphgreenjr.2466]

When I was young, I'm 74 now, and I went where the great bears roam, my side arm was a Ruger SS Blackhawk 4 5/8 barrel in 45 Colt. My hand load was Nosler 300 grain partitions at 1,100-1,200 fps. I figured I had only 2 maybe 3 shots to stop a bear on the move from 25 yards. I saw a fair number of bears, only one got close enough for me to smell his breath and hear him pop his chops. The Ruger was in hand with the hammer back, lucky for both of us , he changed his mind. I would liked to have a .454 Casull! The only thing I ever shot with my Ruger was a Chevy small block, WOW, made scrap out of it. Still own the gun.

[@AlaskanBallistics]

Love the stories! Great choice on the firearm and load! Godspeed and good hunting my friend. Feel free to tell your experiences in the comment section as much as you want!

[@arapahoetactical7749]

Great video and I like that you stuck with the same ammo. I've done some similar testing with .357, but I don't have a 10mm to run it against. I have noticed though, that different revolvers have significantly different cylinder gaps and that this has a lot to do with overall performance, as much as barrel length. My next goal is to run a 10mm side by side against my Coonan 357 with similar ammo to see what I get. Running 125gr .357 through it I was seeing velocities in the 1560 FPS range vs the same round from my Ruger GP-100 4" at about 1500 FPS, but that is here in CO at about 6K ft.

[@AlaskanBallistics]

My guess was 10mm would penetrate more because it’s a heavier bullet. I was surprised the .357 magnum had less velocity, but you’re probably right about the cylinder gap. I liked the test though.

Thanks so much for watching. I'm pretty sure the low velocities in the .357 mag are at least partially gun related. Thank you for the comment

[@dafawty9thstate830]

That was a really inconsistent box of ammo, but, it reminds me also, of when I told you, that .357 Magnum, is not more powerful than 10mm. Especially in the heavier for caliber loads. They do over lap each other very well, and sometimes the .357 will out penetrate the 10mm, depending on what’s being compared. Here, already it’s not comparing apples to apples, because the bullet weights are different, and on top of that, crappy, inconsistently loaded .357 rounds. They are really close performers to each other, but it appears Underwood can’t keep people on the job, that have the care or skill, to produce consistent loads. It could be that the powder used doesn’t meter well in their equipment, or they frankly have an employee that just does not care. I’m sure it doesn’t pay well. The components are top notch, the quality of assembly is not. There are too many variables that can make them both beat each other depending on what’s being used, quality, consistency and component wise, and then the actual guns they are fired from.

[@boedude8496]

@@dafawty9thstate830 as you alluded to a cartridge is only as good as it is made. that is also true for power. off the shelf ammo is quite a bit different than handloads, including bb and underwood. the 357 is capable of greater velocities and energies. since different calibers do better or worse with different weights there is no legit way to compare performance by a specific weight. you can only go by light, medium, and heavy for caliber, picking the best for each. or as many subdivisions you want. it mostly comes down to preference, revolver or auto. and some play the round count game. chances are, if you play the odds, the same job will get done with either

Reliability is a must and I have never had a FTF, FTE etc carrying a revolver in bear country for almost 5 decades. Running speed loaders and being quick with practice you can reliabily rain down some lead pretty fast and I have seen some big bears fold up pretty quickly from a 357. It's just a matter of personal preference. They both will do the job.

When accompanying my adult son on his elk hunt this past year (in grizzly country), I carried a 12 gauge shotgun with Brenneke's slugs and a .357 mag with Buffalo Bore loads as a backup.

[@AlaskanBallistics]

Make sure that you waterproof those slugs. Slip in a river or stream and they're toast

No but having more rounds is important as you'll never have more foot lbs of energy with a bigger gun, even 50 bmg has less ft lbs of energy than a charging 800 lb bear at 25 mph. 10mm has sufficient penetration, so with more rounds, and most people shooting semi autos better, why would you not want more accurate with more rounds?

@@AlaskanBallistics I mean I get the fear factor and all( though I didn’t grow up around brown bear country I grew up around alligator country) . But autos are subject to failure to feed and such not to mention some are more complex. Glocks are a little different in that they utterly simplified the automatic pistol leaving out safety’s and double action - it’s just pull trigger and go. Having said that you must still rely on proper function whereas revolvers are simple : keep pulling trigger until empty!! I guess since I grew up with revolver not automatic pistol( until adult) it’s in my blood. I love auto pistols more than anybody ! I have a beretta performance X competition pistol( among others) but my SW 686 plus is what’s by my bed not beretta because in the middle of night I don’t want to fiddle around with safety or other issues just get r done. I don’t own any glocks so there is that. The increased ammo is really main advantage unless maybe you say faster rate of fire.

My two cents on best bullet for bear in 10mm-175/180 gr truncated cone pushed at max velocity.

Keep in mind that 357 mag has more potential than per round than 10mm because it has more case capacity and can be loaded way hotter because revolvers don’t have to same pressure limitations that semiautos do, and with a 180 gr bullet 357 Mag has more Sectional density than a 200gr 10mm, theoretically having a advantage when compared at identical velocity’s.

Having looked at a lot of numbers and penetration tests, 10mm seems to be just about the best round out there for applications other than concealed carry (I'm not saying it can't be a good CC round, but lots of people have criteria for a CC gun that would rule out lots of 10mm pistols. If you don't plan to CC, those criteria go out the window). I think it has the best balance of mass, velocity and surface area of pretty much all the calibers out there. Carry it in a full size or competition/long slide gun, and you've got yourself a hell of a package.

Logan Waltz - The .357 was a 6” barrel. And hard cast from a .357 is not much of a hunting cartridge. Small diameter hole, low velocity compared to a rifle, essentially non expanding ammo.

The standard deviation on the .357 Magnum was high, indicating there may well have been a quality control problem with the ammunition.

The only question I have is this, which ammunition (company) Buffalo Bore , Double Tap for example were used?

[@AlaskanBallistics]

Good news is that I have some buffalo bore to test in episode 2 of this.

[@williamschramm2761]

Thank you for your reply. From my research the 10mm is slightly more powerful than the 357 mag. However, the 357 has much more uses for a shooter due to the fact the 357 can fire 38 which has many distinct rounds and the 357 which can fire rounds from 125 grain to 200 grain. Due to this fact , I prefer the 357 due to the simplicity of the revolver. The most powerful 10 mm round is stronger than the 357 round, however, in my opinion, the difference is not significant

[@AlaskanBallistics]

I think that's a totally valid point, but either is undergunned for big Grizzlies, but good shot placement and they'll work

[@williamschramm2761]

You are 100% correct !! From what the info. I have gathered, pepper spray is the best weapon for a charging Grizzly. If the Grizzly is charging you at full speed, the only instant death shot is in the brain. Good luck with that!! I would carry a 12 gauge slug gun or a 45-70. I have Ruger Supper Red Hawk,7.5 barrel, which can fire Bufffalo Bores 44magnun+p+ which is very Close to the 454 Casull but I would not want to use it due to the powerful recoil. I will get the first shot off, maybe the second. Note: I am 210 pound man, weight lifter stands 6 feet 2 inches and the round is very challenging for me to use and handle

Although 180 gr of hard cast lead going 1200 fps, is definitely still making it through a grizzly skull.

@Ben Woodcock If you get off seven shots at a bear, you weren't in danger when you started shooting. Most bear attacks don't give you enough time to get off four shots. If you can't get it done in two, you might as well carry a note asking to be buried with all that extra ammo.

No disrespect, but that's bullshit and already been debunked, modern revolvers have the tightest cylinder gap and much stronger forcing cones that don't break as easily as older revolvers, they don't lose that much gas, plus the revolver has a true 6" barrel and the Glock 40 kkm barrel is 6.5" but you only using 5.3 because of the chamber and overall length of the cartridge, also if you don't use at least a 22lb recoil spring you're losing gasses through the breach.
