10MM vs. 357 SIG

[@luket557]

357 sig is really underrated and over looked by alot of people. 357 sig ammo can cost alot but if you know where to look you can get 50rds for around the same price as some other calibers.

[@luket557]

Just got to beware of what ammo your buying.

[@Lexicologist1971]

The same goes for 10mm. Much of it is loaded for under 1100 FPS with a 180 gr. bullet. Sig and MagTech are at least medium loads. American Eagle is loaded to 1030 FPS. Winchester is loaded to 1080 FPS. That is according to the box, not a chrono in my back yard.

[@Ujiyo]

I got a box of +p 357sig for $19.99 truth be told though, bulk buying .357sig is expensive. Really expensive. Lowest price I've found is $0.37/round and that's FMJ ammo. Hollow points get up around $0.88/round.

[@jasonvoorhees2701]

I've seen .40 just as hot as 10mm these ammo manufacturers are full of shit ..give us what we pay for ...and we want ..

[@MurdamittenG]

@@jasonvoorhees2701 thank you!! 10mm is 💩 unless you’re loading your own. Just get +p .40 and get the same velocities, even better if used in a carbine pistol!

Wow. Great test! Same ammo manufacturer from almost same length barrels. I have some of that Sig 10mm for target shooting. Great for getting close to full power.. 10mm has just a tad more thump. Neither are a slouch. Best semi auto for carry IMO. Thanks for the test!

[@thinktwice8860]

Speed penetrates more. I’d be highly interested seeing these two calibers compete with similar rounds of Underwood Extreme Defender. These use a copper bullet that won’t expand. The Underwood Extreme Defender comes in 90 grain 357 sig round, and a 100 grain 10mm round. You may need to have up to 20 + inches of fiberglass boards to shoot into. These rounds penetrate very deep.

Speed doesnt always penetrate more.

[@thinktwice8860]

@@northernninety7 You’re right! When the projectile deforms (such as mushrooming), the increased friction can greatly affect penetration.

10mm is the best round in my opinion. Great for EDC and with just a mag change can be used for hunting or protection from big animals. Gotta get some underwood to get the best true 10mm

[@donniegray2288]

The Glock 10mm has polygonal rifling and a tad bit longer barrel so the .357 may have had a tiny bit more velocity in a Glock but prob wouldn't have been that big of a difference.Great comparison tho and both are very stout rounds.Love my .357 Sig's and gonna buy a 10mm for extra woods protection.

[@9unslin9er]

Bottleneck creates higher cartridge pressure and is a better design than straight-wall. The fact they are performing neck and neck makes .357Sig superior. Makes you wonder how a .40 Super would perform in this matchup.

[@thegreenberetlife0191]

Good comparison! Those look like old Amoco (Standard Oil) self serve signs…. .357 is a very underrated round that is accessible as it can be shot from a gun designed for .40! 10mm is excellent but not everyone has a 10mm gun…

[@roncoon3464]

I've got a Glock 20 & 29. What I like about the two and their relationship to the 10mm and .357 SIG rounds is that they are both out of the same cartridge, the .40 caliber. The 10mm is a .40 cal in a longer cartridge for more powder and the .357 SIG is a 9mm in a necked down .40 cal cartridge. So, with the G-20/29/40, you've basically got 3 guns in one; the 10mm, the .40 cal, and the .357 SIG all in one. To go from one to the other, all that is necessary is a simple swapping out of the barrel. Everything else is compatible from the magazine up to the barrel.

[@marthapugh5998]

Ron Coon not quite. The 10mm case is beefier than the 40sw as well as longer. This allows for greater pressures. The 357sig is based off of the 10mm not the 40sw.

10mm all day every day. .357 SG is no slouch and very underrated but 10mm (esp. out of a G40 or a long-barrel G20) can be viable hunting round. I've been carrying a 10mm into the PNW backcountry for decades and the one time I needed it to put down a charging Moose... I was glad I had a 10mm.

[@richardcheese4722]

How many rounds did it take? What pills and grain

[@Lift_these]

The sig was moving faster by 100 feet per second. I would say if the 10 was the same speed it would cause much more damage. The whole was larger in the 10 which “may” equate to bleeding out more quickly. So if we went with a slightly lighter load for the 10 allowing it to move faster, the 10 would be the better round, in my honest opinion. I Love the 10 but the sig is right next to it !

180 grain FMJ out of a 10 is really weak compared to what you can get out of the caliber with other ammo manufacturers aka Underwood, Buffalo Boar or Cor Bon.

The 357 hit just a little bit harder and got just a tiny bit deeper. Nice display of penetration though. Should do like a tournament between the rounds.

The 357 Sig is without question the superior round. Even though on this specific test, the two rounds appear to have penetrated the target somewhat equally, the fact is, the 357 Sig fires with higher velocity, and a flatter trajectory. In other words, more accurate than the 10 mm.

[@ThePenetrationChannel]

Yep. It was part of their original lineup. I bought mine in 2009. Glad I got my hands on it. Thanks for watching.

[@rodwspoon304]

Maybe I might buy a 357 sig barrel for my g23 just to check it out great video bro

[@ThePenetrationChannel]

Thanks for watching! The 357 Sig is a great round. Though not as versatile as the .40, it out performs it in any loading from what I have witnessed.

[@a68rebel]

You don't see a difference between the 2 calibers???? How about the hole the 10mm made that was almost twice the diameter of the 357 sig?

[@69CamaroSS]

Use Underwood Ammo Extreme penetrators in both calibers....and if you *REALLY* want an apples-to-apples comparison, get a conversion barrel for your Glock and everything besides the cartridges will be equal!

[@eldesgraciado6690]

"The Penetration Channel", AWESOME!!!!!

[@Lift_these]

The double tap 135 grain or underwood 140 grain would be closer in comparison. If they are not frangible rounds.

[@jeffioiselle7982]

I agree it's pretty safe to say that the 10mm with 100fps less bullet speed and 55 gr heavier weight round is a dead tie to the lighter fast 357sig. This 357 sig is gonna continue to be my round of choice over the 10mm. Simply because the round is so flat shooting. And all the other benefits of the 357sig round. Granted it does have 2 major draw backs for the meek. 1 load bark aka blast. And cost. As far as cost I believe my live is worth the cost of the ammo.

[@ThePenetrationChannel]

The ammo cost of 357 SIG is pretty comparable to the other semi auto calibers where I'm from. I just wish it came in a larger array of weights. Thanks for watching.

[@reachblowsdick7222]

@Jeff Ioiselle - In the video the 10mm was a 180 gr. and the 357 Sig in 125 gr, so yeah naturally the 357 Sig will fly faster. But compare it to the 10mm in 125 gr, and it's velocity is at 1600 fps at over 700 ft/lbs of power. That's significantly faster and stronger than the 125 gr 357 Sig and the 10mm will shoot much flatter. This guy should have done a more equal comparison like both calibers in 150 gr or so. The 10mm is stronger than the 357 Sig and depending on the right ammo choice even slightly stronger or equal to the 357 Magnum. Both 10mm and 357 Sig sound about the same in noise blast, but the 10mm in lighter grains with Underwood, Norma or Buffalo Bore and people will think you're shooting a 5.56 AR. There's a reason why the Glocks make the pistol frames and slides bigger for 10mm, while the .357 Sig Glocks are smaller both frames and slides. Shoot a 10mm G29 with pinky extension along side a 357 Sig G32 since they're both very similar in size, and you'll feel the G29 jump more with far more snap. But 10mm are harder to find. If I'm gonna shoot a caliber as expensive as 357 Sig, I'd rather get the 10mm since it's stronger and more fun to shoot. The 357 Sig feels to me like a hot loaded .40 S&W

[@jeffioiselle7982]

@@reachblowsdick7222 he specifically said in the video the velocity of the 10mm. And it was not 1600fps.

[@jeffioiselle7982]

10 mm was 624 ftlb of energy @1250fps...357 Sig was 506ftlb of energy @ 1356fps ...in the end dead even performance. 10mm vs 9mm ...dead even.

[@reachblowsdick7222]

@@jeffioiselle7982 - You didn't read my comment carefully. I said the 10mm in "125 gr", not 180 gr like the 10mm he used. The 125 gr 10mm has a velocity of 1600 fps, not 1250 fps. Also the 125 gr has around 700 ft/lbs, not 624. You didn't read up on the grains of the 10mm. He didn't use 125 gr 10mm, he used the 180 gr 10mm. He should have used a grain both in similar grains. Both calibers in 140 grains for example are listed as this. 10mm 140 grain: Velocity: 1500 fps Energy: 700 ft/lbs .357 Sig 140 grain: Velocity: 1352 fps Energy: 500 ft/lbs As you can see that both calibers in the same grain, the 10mm is noticeably faster and more powerful.

Watch your lungs messing around with that fiberglass dust bud. I'd buy some of them 3d masks my friend.

@@5shotsr611 will do. Thanks for the advice. 👍🏻

[@9485881]

Why not compare with hotter loads for both calibers? Theres 10mm rounds that can produce 700 plus ft lbs going at 1500 FPS as well as 357 sig loads that match the same power.

[@tomb4568]

Have em both like em both flip a coin! I will say I have tried Underwood 65GR 357SIG rounds and they absolutely are smokin!

[@jeffioiselle7982]

Try rbcd 357sig 2410 fps and 774 ftlb of energy....they are VERY expensive though. If you want the best for 357sig that's the hottest stuff I know of...

I like the 10mm 👍

but was the 10mm full power 10 or watered down store bought

10mm is more power but necked cartridges feed better.
