.40 s&w VS 10mm Ballistics Gel Test 

All I know is .40 ain’t short & weak as a lot of people make it out to be. That’s not even a premium load and still did damage. Great video! Thanks

Both the 40 S&W &10mm are loaded Light. You can easily push a 155gr bullet out of the 40 to 1300fps. The 10mm can easily achieve 1550fps with the same bullet

Finally! Two identical rounds with exception of caliber are compared. Excellent.

Ok, this is a very, very good comparison test. I wondered how much difference there is. Now I have a solid answer. In some ways there isn't a great deal. In other ways the 10 is noticably "greater" in "power". But overall performance the 40 demonstrates it's ability to deliver great results. It holds it's own even with the big boy 10. Many thanks. This is one of my first 40 carry choices way back in the late 90s when I switched from 357 mag revolver to the 40. Here it is 25 years later and still a top option.

That 40 was just perfect and hot too.

Just goes to show how poorly loaded every .40 sw load is unless it is Underwood! Love this round and am excited to see you do the underwood versions!

They both smacked hard

That 40 ain’t no punk. Still a relevant cartridge and 10 is rising like a rocket in popularity.

My man thank you I’ve been waiting on this comparison thank you for the great video 👍🏽

Great video man! I love the .40! I would like to see a video of the federal hst 180gr vs the 165gr. Not sure if you already have a video on that or not.

Yay for 10mm Long and 10mm Short !!!!!!

Hell Yeah! Let’s Go!

When I made the decision to switch from 9mm - bypassing the. 45 ACP, which I've been shooting for over 50 years... yes, I am an old fart! - and going straight to 10mm, one of first bullets I tried was the 155 XTP. Ok, this was because my preferred brand, the 165 gr Speer Gold Dot had become "unobtainium!* for some unknown reason! In the past, I've had more than a little trouble with these XTP bullets, in both 9mm and 45 ACP seperating the jacket and core in my water test medium, so I wasn't holding a lot of hope for these bullets. I was pleasently surprised to find that they did not do this, even at a velocity exceeding 1300 fps! There was a huge down side, however, since they were barely able to hit 10" of penetration! Personally, I want to see 16 - 18" of penetration. This pretty much eliminated the 155 XTP. I am now working on the 180 XTP but with winter coming on fast, working with water is not in my tool bag right now! Of course, my carry ammo, the Underwood loading of the Lehigh Xtreme Defender bullets makes this every time but I wanted a bullet I could load myself as backup ammo without breaking the bank. While I can load the Lehigh bullets, my velocities are not in the class as the factory (Underwood & Lehigh velocities are the same) so I am forced by logic to use the factory ammo since these bullets work on velocity. Time will tell regarding the 180 but to honest, I usually go for a light for caliber bullet, depending on the extra velocity to get the bullet to work the way they're supposed to, e.g. 115 for 9mm & 185 for .45 ACP. The 165 gr. Gold Dot seems to me to be the perfect weight for 10mm, but alas, they seem to be no more. Speer says they are in "full production" but I haven't seen any for sale anywhere in over 2 years and they no longer even list them on their website as loaded ammo or as components! Dang it, Speer, what's up with you guys? Oh well, I certainly can't *make* them sell me their bullets but I sure wish they would get off the pot and get going again! Time will tell but I'm not holding my breath! Anyway, great test and it confirms what my testing showed, so I am grateful for that! Keep up the great work, you've been hitting the nail on the head and I love that you're using 10% ordance gel instead of clear as the results are much more dramatic than the clear gel! Cheers, jc

I saw a picture in an article by Evan Marshall of that 40 round that had been taken from a would-be rapist’s body. It looked just like that one. I used to carry that 10mm round in my custom 1911. Both are awesome loads.

I have and shoot both but .40 is a favorite of mine. The 10mm is more powerful, but really if you reload and use the right powders for both, the 10mm isn't that much faster than .40 S&W from the same barrel length, roughly 100 fps, give or take 25 fps either way.

There are no flies on the 10mm kurz.

Yeah the 10mm is more powerful. But on the basis of this test, I'd say not enough of a difference to make a difference. It validates my decision to go 357 Sig instead of 10mm. All I had to do was swap a barrel. I believe 40 is no slouch, hell, it was my EDC for many years until I fell in love with my micro-9's and 357 snubbies. 40 and 357 Sig get game time on the deer lease.

Greater momentum over an equal sectional density, can actually unfurl a hollowpoint faster, equalizing penetration between two rounds with very different power levels. Since .357 hollowpoints are of smaller sectional area, they can penetrate further even if less powerful. Narrower projectile = less drag.

I could swear that I saw a small thermonuclear explosion as that 10mm started penetrating that block. LOL Big brother does some massive damage, but little bro can hold his own as well.

I'd like to see that .40 against the 10mm with a 180gr at the same velocity.

40 vs 45

Great video! You're about to make me by a 10mm glock 😂

Good video undecide on 40 10mm or 9

10% more of everything

Can I ask for a test ? Ammo 9mm Norma SAFEGUARD 124 GRAIN SHORT BARREL.

Remember. The Magic Man load is200gr×1000fps,4in.barrel.says the Guru Keith= Model 58 41rem.Cop load.210grain×1100fps.js.😊

Glad to see you not using clear ballistic gel, defiantly illustrates the energy better

These results are a perfect example of why 10mm hollow points don't make a lot of sense in my opinion, you get almost identical performance from the considerably less expensive .40S&W which has less recoil as well. Now properly loaded 10mm hard cast are an excellent big bear defense option because the extra velocity helps a hard cast but that extra velocity causes the HP's to expand so much, so fast, they really don't give you anything more than you can get from other calibers.

This is why I always say that 40S&W is a better choice than 10mm. 10 doesn't do anything better than 40 is and it breaks apart or deforms. Even for bear defense 10mm is has diminishing results because the velocity is too high for a projectile of that size to handle. What is needed past 40S&W is a larger caliber and that's where 45auto fills the requirements. More weight and bigger bullet resets the maximum potential. The 40S&W are relatively small bullets compared to 45auto and is already being pushed quite fast. The 10mm was created to replace the 357magnum not for being a man stopper, but for penetration of vehicles and auto glass while still inflicting damage. When 357 Magnum was first utilized, it was not killing criminals but rather making hits on them as they got away. This required them to seek a hospital which will eventually get them caught or at the very least slow down their criminal activities. It was not the predicted outcome, but it was a favorable one. If the 10 mm can achieve a similar outcome it will be effective. Everybody thinks they know why the 10 mm was eventually replaced with the 40 and 9 mm, but they have no idea. The real reason is because cars were no longer steel and difficult to penetrate. Even a 9 mm can penetrate into a modern car and the need for magnum rounds was history.

Love the tests, but I just ignore the commentary because this guy's voice got so annoying after a few videos. I just skip to the details and leave on mute.

Another tremendous test by AZ Airgunner. This is real world, true facts and figures..Not some artificial, ammo manufactures wet dream. Both the 40 S&W and 10MM were star performers.
