45 ACP vs 10mm: Unbelievable Difference On Barriers

On this episode of Ultimate Barrier Testing, we will be comparing the performance of the 10mm Auto to the 45 ACP on 4 different targets. Each target is worth 25 points (winner takes all), for a grand total of 100 points. Whichever cartridge ends up with the highest score will be the winner. Tests 1-3 were setup at 10 yards and test 4 (minus the steel) was setup at 5 feet. Thanks for watching!
10mm: G20C
Tests 1-3: S&B 180 gr FMJ-FN ~ 1,164 fps - 543 ft/lbs

Just make sure your 10mm isn’t underpowered. I’ve heard and seen a lot about some 10mm loads basically being .40 S&W

It's true that 10mm has been watered down but it's still much more powerful than 40s&w.

.45 was actually designated as the smallest caliber necessary to dispatch bovine in the Thompson LaGarde tests in 1904. Tests which were conducted because during the Moro Rebellion, we were fighting against doped up Phillipinos who didn't care about getting shot with a .38 caliber. Enter the Thompson LaGarde tests where .45acp was proven as our next pistol caliber by dispatching cattle. John Moses Browning then designed the 1911 around the .45acp cartridge. So technically, you are right, but technically, you are wrong. That particular caliber was proven to kill cattle within 10 seconds of a lung shot. It'll kill a bear.. it'll also kill a doped up phillipino who dgaf about being shot with a 9mil

That being said, double tap is still vastly superior to the Federal round which was tested! I would place double tap between the high-end boutique rounds like Underwood and Buffalo boar and your larger companies like federal, who refuse to load the 10 mm to the old more respects because the lawyers get involved and so large companies like federal will not load the 10 mm to its original Specifications and true potential.

Sorry, but 10mm beats 45, even when sticking strictly to the FBI standard. There are many loads to choose from. Also, CLEAR gel is NOT used for the FBI standard AND the block is only 16" long, which does not allow for the maximum 18" penetration for the FBI standard. Don't be biased.

If you're going to carry a carbine you might as well just carry something like a Kel-Tec 12 gauge with slugs I did a bunch of research and the most common Grizzly defense gun in Alaska is a 12 gauge with slugs

[@trevornetlink4715]

Dumping all 230 grains of energy in 4.5" inches of wood is the reason it was used for trench warfare in WW2. Marines and Army couldn't afford to have the enemy take a handful of shots after being hit a few yards away. A 230gr 45acp was a meat stopper. The Colt 1911 by browning design and the Thompson .45 machine gun was massive in urban combat. Its design was perfect for 50 yards or less and made big holes after being hit very very hard. With high adrenaline some solders didn't know they were even hit with the 9mm , not with the .45 it was a bone breaker with shock and awe.

[@FirstnameLastname-do1px]

Complete and utter bullshit. The whole reason 30 carbine was developed was because .45 loads back then were anemic when compared to today, and were shit at penetration.

[@salt_97]

[@MasterTaters]

@@FirstnameLastname-do1px Uh man, you gotta remember the common pistol rounds of the day; it's not exactly bullshit. 7.65 longue, .32 acp, .380 acp, 9mm luger; it is superior to all of those in the factors he mentioned provided they are all using FMJ rounds. Today it might be more of a joke as FMJ; back then it was the strongest commonly available pistol caliber; and .30 carbine is an intermediate caliber so it's not really in the running, thats like comparing apples to fish sticks. Also I think he meant World War 1, and in urban combat within 50 yards; weapons using this caliber off handgun round(key word, handgun) Had an advantage over the other commonly used, handgun ammunition supplied; *Sub- machine guns* So it's really an issue of context. The .45 acp also existed for 37 years longer than the .30 carbine, which only achieved widespread distribution toward the latter half of ww2; and then mostly in the hands of 2nd line troops. Also during the korean war and vietnam, the .30 carbine was heavily lamented by those who wished they had stronger, longer reaching cartridges like 7.62x51mm nato; they would even chose 5.56 over that if given the opportunity during vietnam which was the last common use of .30 carbine. Fudds today say .30 carbine was bad, 5.56 was bad, and 7.62 nato was even bad in comparison to .30-06. Before the .45 acp entered service I'm sure german fudds thought anything that wasn't at least 9mm luger for pistol caliber was also bad but they got one upped on that in less than 4 years.. So really man, you just come across as a fudd; and nobody likes fudds.. Don't compare burgers to burritos...

You make a good point. A 10mm is very powerful vs other choises. Matter of fact, if the 10mm passes completly through deer size game and in a woods it continues on, likely stops in a tree or in the ground. Inside a home, a pass through can result in a very bad and an unintended end result. IMO

[@texasbeast239]

As a matter of fact (not opinion), 10mm was created to be the superior self-defense caliber by most consistently penetrating deeply enough to hit vital organs and immediately stop bad guys, without overpenetrating. It is intended to bias towards the far end of the 12-18 inch penetration range recommended by the FBI. 12.5 inch by the .45 is barely passing. That's like getting a D on a test in school. The FBI also acknowledges no known actual overpenetration deaths or lawsuits by these calibers, so the fear of overpenetration from a defensive bullet up to 10mm is overblown. Now, .41 or .44 Magnum? Yeah, good luck keeping those within the penetration limits.

@@MrCora1212 Not really out of context. Majority of GSW are smaller calibers like the 9mm. From a medical standpoint, having an entrance and exit wound increases the rate that someone loses blood and increases the chance of the wound being fatal. From a defense standpoint, an exit wound is a bad thing. If you shot an assailant, and the round, after exiting the target, strikes anybody or anything of value afterwards, you're liable. The property owner can sue you, or an individual that was shot can sue and press criminal charges. So from a self defense standpoint, you want your round to create large temporary and permanent wound channels in shutdown organs and cause loss of fluids, but not go through the subject and strike another person or valuable object. The 45 ACP moves slower (around the 800-850fps) is less likely to over penetrate a target compared to a 10mm traveling around 1200-1300fps.

The AARP bullet penetration capabilities vary widely, of course, with the ammo selection which is one of it charms, in my opinion. Heavy cast bullets from someone like Buffalo Bore put its penetration levels right up there with 10mm. Cool test.

[@jkent9915]

Nah, comparing 10mm vs Buffalo Bore .45 +P: the 10mm has 50% more muzzle energy and a smaller frontal area. A .45 +P load is 800J. A standard 10mm is 900-1300J. Even compared to the .45 +P the 10mm is closer to the .44 Magnum in ballistics 1000-1400J. (.41 Mag is actually REALLY close in bullet size, weight, speed, case volume, and muzzle energy) Also worth noting that you could be 9:00 paying upwards of $2 per round for those Buffalo Bore +P rounds, and every normal 10mm hits harder than that for $.40-$.60 per round. That only matters so much, but you have to shoot a few of those +Ps before you need them because they are SPICY compared to a normal .45 and it can be like shooting a whole new gun. I’m not saying it’s better, just different. .45 is better at stopping in a target causing maximum tissue damage. The 10mm is better at punching holes, whether that’s barricades or body armor. The greater energy just lends a bit more versatility to the 10mm allowing it to really shred some hollow points.

[@bradmiller9993]

well I agree with you, actually. I only use the buffalo bore stuff for potential dangerous game encounters.

Just a thought: controllability enters into their defensive capability equation. If a .45 is more controllable than a 10mm, then the all important follow-up shot issue comes into play. Also, the .45 on the first tests was a flat nose commercial vs. a military ball round. That would certainly make a difference in block penetration. Finally, it would be instructive to see if a +P .45 would really make a difference, or a .45 of 180, vs 230 grain weight - after all, energy goes up as the square of the velocity. Interesting video.

[@bobjohnson1633]

Ft lbs is meaningless. You want to consider the momentum. Momentum and sectional density determine the ability of a bullet to penetrate. Momentum determines the recoil force. A 45 acp and 357 standard loadings have similar momentum, though the 357 has a much higher sectional density and much lower bullet weight. The 220 +p critical duty is hauling ass for a 45acp, and it's a heavy bullet at that. Unless a bullet is travelling multiple thousands of fps, don't worry about ft lbs of energy

[@MrGsteele]

@@bobjohnson1633 Well, not meaningless, but certainly the momentum of a bullet is grossly underrepresented in discussions about penetration in videos and posts. It's also the case that - particularly in handguns, with their normally short barrels - acceleration to a higher muzzle velocity requires higher pressure, bringing with it greater muzzle blast and powder-related recoil force. That energy-seeking path costs controllability as a result, whereas heavier bullets at lower velocity are tamer and more controllable.

Is it possible to know how much energy was _really_ dumped on the target, considering how much remained for the round to end up in Belize? I suppose you'd need a chrony in front of the gel, and one on the back to test that. In any case, both rounds are great.

Depends on the target. If you live up north during the winter, projectiles are shown to have irregular results because of layers of clothing. sometimes the hollowpoint gets clogged and doesnt expand. Sometimes the slower subsonic speed of a 45 might be affected by layers of clothing. Body mass and Fat can affect penetration as well.

[@cgsimons1187]

For self-defense against typical 2-legged predators, yes. He also used a bare gel block rather than putting a layer of clothing in front. Clothing tends to inhibit expansion to some degree which tends to result in deeper penetration. My guess is that both bullets would have expanded slightly less and gone deeper. Which means in all probability the .45 would be closer to the sweet spot of 15" while the 10mm would have gone past 18". I believe where the 10mm shines(with the proper load) is for defense against larger animals.

[@myblacklab7]

I think so, and less penetration is better in most urban environments, unless you're shooting through hard barriers for some reason. I haven't heard of a .45 being stopped by winter clothing and fat, and would be curious to see any examples of that actually occurring.

[@syrin1237]

"Stopping power" is a catch all term for whatever stops the threat. Penetration is the most important factor for stopping power. You want the damage to reach vital areas and failing that blood loss is the next surest way to stop a threat. However, sever over penetration is simply a waste of energy. The more energy dumped into the threat creates larger wound channels and a more dramatic impact which can also "convince" the threat to stop. You can achieve this ideal balance between energy dump and penetration with any caliber by selecting the right ammo. But what alot of people don't seem to get is the more powerful a caliber is the more potential it has to deliver stopping power each shot...pretty simple concept.

In combat for many years. It can hold up to 15 rounds in double stack,and 9 rounds ln single stack mags. The fat case can hold more powder,and could be made for heavier rounds at faster speeds. Once again you can find ammo much easier . .

[@TechieTard]

The traditional weight was 200 grains, not 230. 230 was a home defense round. You want to surpass the 10mm, just lower the grains on the bullet.

[@greenchef6]

@@TechieTard 45 ACP can never surpass 10mm. It's pressure limit is too low.

[@pastrypopper2239]

It might be worth going back to this test with some full power 10mm. The Federal HST is alright, but S&B 10mm is extremely watered down with the box velocity coming out of a 6 inch test barrel. Don't even bother with the federal american eagle red box, it's just long 40. To really see the true power of 10mm, look for Underwood and Buffalo Bore. The Sig Sauer ammo is also pretty good.

[@jtnord]

Those 10mm loads are weak range loads (yes I know one is HST). You should try some full power 10mm that is 650+ ft/lbs

[@joshmatlock3410]

Agreed, Buffalo and Underwood pack a punch

[@anonw3829]

what I see is 10 mm = over penetration. .45 wins it for me. Plus look at the jelly jump back a few inches when the .45 hits. It moves the jelly back further than the 10 mm does

Great video. Both cartridges are great. But 9mm, 10mm, 45ACP… they are all gonna stop the bad guy.

[@donhearn2248]

I owned both a Colt Delta, and Kimber .45.... I love the form factor....but since I am not, nor have I ever been in a war...I prefer the .45...this guy kinda demonstrated why....just look how often his 45 was almost dead center, vs the 10mm. 10mm is a hot round and not nearly as gentle to shoot as the .45. Personally if I was going to CCL, I would get one of the new 8 shot 357 mag revolvers, if I wanted to defend the house..I would just stick with a 12 gauge. To me my .45 is just a range toy from back when I was in a shooting league.

Years ago a guy shot at me in my house.

It went in about 5". The cavity in those HP bullets is much smaller than what they make today. I kept that bullet as a souvenir of how important our Second Amendment is.

@@SpikeJonesTheCr0oked I would assume they meant using Double Tap 10mm as well, since Double Tap are known for making and selling good hot 10mm loads.

[@Mockturtlesoup1]

I've always wondered how one of those light for caliber 10mm rounds(like 135gr) would do in terms of terminal ballistics, and especially relative to the recoil it generates. Back when I used to carry .40(I was not wise in the way of gun-fu when I bought my first handgun all those years ago, and decided on a g23 instead of a 19), I used Cor-Bon ammo. One load was the 140gr DPX, and the other was a 135gr PowR'Ball, going 1325fps. Both of those loads have significantly less recoil than the traditional 180gr rounds. Put that round in a 10mm case(granted, you'd probably want a projectile made for higher velocities) and that thing would be _screaming._ Actually, that makes me wonder what a super light 10mm projectile would do. Like how there are 9mm rounds with 40, 50, 60 grain bullets, and they're going 2000+fps. Load one of those in a 10 mil, and I feel like you'd be flirting with rifle type velocities.

[@anubis8680]

Liberty Civil Defense, claims 2,400 fps out of a 60 grainer. 5.5” 10mm 135’s I got cooks at 1550, 1425 out of 3.8” barrel. 9mm Liberty civil defense reached a deer heart, to finish a spinal shot on a deer. Clipped a rib too.

I've had much better results with .45 acp + P, (a bigger heavier just as fast bullet) over the 10mm, plus this allows you to just change magazines without having to buy or carry two pistols.

[@richardcox6935]

I use some +P 185 gr. hard cast led rounds in my 45. I wonder how a comparable 10mm round would stack up against that?

[@jorgesolis9468]

Against true 10mm no contest 10mm wins

[@Mirage5892]

10mm has about the same powder, can be loaded with 230gr projectiles even tho 180 is more common. So the same input energy and mass, over a smaller area. That means more pressure. More pressure for the same mass means more velocity and output. The 10mm was designed to be an optimized 45, and it succeeds

[@jorgesolis9468]

@@Mirage5892 yep basically not to mention thicker brass as well which is why 45 super came around also followed by 460 rowland but 10mm continues to be the most powerful readily available production pistol round there is

[@Joe___R]

Even though it likley wouldn't have changed the results, you really should have used 185 grain 45acp +p. I would like to see how 460 rowland would do on your test, especially with an extreme penetrator bullet.

[@LJ-gn2un]

With all due respect, and no offense meant, but this really isn't a true representation of the venerable 10mm round. The original Norma specs called for a 200gr solid at 1200fps, yielding close to 700 ft/lbs of energy. The rounds you used for these test are basically the 'FBI lite loads' developed for the FBI folks that couldn't handle the full powered 10mm loads, hence the later developed .40 S&W (Short & Weak). Only a few companies still produce rounds with the original power levels, and unless you "roll your own", which I do, there's no comparison! The original loading are almost equivalent to the S&W 41 magnum, which is NOT "short & weak"!

[@Texas2Step79]

The fact you call.40 short and weak automatically discredits your argument..

[@Omalleyus]

I love things like 10mm. but every test ever seems to just always show for a handgun you literally can not beat 9mm. more rounds than 45. and almost the same damage. smaller than most of everything else. lower recoil than everything else other than .38 and 5.7. almost no chance of over pen and super common so no legal nightmare for using it. it's also at most times of the year the cheapest for both ammo and firearms.

[@1retiredknight]

The 9mm had benefited hugely from improved bullet design over the past 30 years. Most of the negative opinion of it going back to the 1980s and 90s were due to projectiles that did not function optimally within the velocity envelope of the 9mm Luger round.

[@HWG-wm8ld]

The same people that say 9mm isn’t enough are the same that bash the AR, clueless and zero experience types.

[@1retiredknight]

@@HWG-wm8ld You have to clarify enough for what. For close range defense against threats of around human size and smaller 9mm with modern projectiles is pretty effective. If you might have to deal with a wounded moose or angry bear, other rounds may be a better choice.
