Also, Paul Harrell says “velocity should increase with longer barrel, up to a point”. It depends many factors like powder type, bullet, etc.

[@scottcooksey5284]

Who in the world was saying a longer barrel was slower? A longer barrel produces more energy also. It would have to be ridiculously loooonnnng to adversely affect it.

[@johnkeisterelquattro2553]

People who know ballistics. In general, yes, a longer barrel will give you more velocity and energy. BUT!!!….. every caliber has a sweet spot. And some ammo will be faster out of a 14” barrel, then say it would be out of a 20” barrel. It doesn’t have to be ridiculously looooooonnng to adversely affect it.

[@Perry2186]

i think i know what some people were thinking cuz at a point the riffling will drag on the bullet cuz the powder is exhausted 16 is not that point tho

[@mikefranklin1253]

We tested (cowboy rounds) revolver rounds out of rifles. In almost every case, the revolver gave higher velocity. I believe the round expended it's energy rapidly in the first part of the barrel then was slowed by fiction as it continued through the barrel.

[@ZeroXSEED]

Pistol catridge didn't slow down until you reach ridiculous number, and at that point people would question "why you have barrel that long" 10mm cartridge is suitable to around 18 inch, but longer than 16 inch is overdoing it.

[@johncmitchell4941]

It's kind of about max pressure and expansion ratio. 'Handgun' powders burn quickly but higher pressures (jacketed vs lead) don't fall off as quickly as many expect. Example: CB Long is rated say 710 fps. From my 4" Ruger KP4 or my 23 1/2" ZKM I chrono'd 700fps. I concluded that pressure after the powder burn offset friction of the longer barrel. YMMV but I imagine .460 & /.500 S&W gain quite a bit from a longer barrel, esp vs such as .45 LC. IMO it's motly about max pressure vs expansion ratio. (AKA case capacity vs barrel volume)

Depending on the powder type used in a 10mm you can see gains even up to 18 inches of burn time. Unless a fast powder type is used but that's when reloading for your barrel length is optimal.

[@johnndavis7647]

That's why the German submachine guns were so popular in WW2. The longer barrel gave the 9mm more velocity and power than the same round out of a pistol. Some rounds gain more velocity than others. The more case capacity and slower powders gain more. The 357 and 44mag are outstanding out of a carbine barrel. The 10mm ought to gain 40% more energy out of a 16 inch barrel with the right powder Is that a Glock magazine you are inserting into that carbine?

[@blenhinton7566]

In my experience, longer barrel = more velocity up to a point. It can eventually reach a point of diminishing returns. The 14 vs 16 would be interesting to see for the purpose of exploring where the point of diminishing returns is.

[@ZeroXSEED]

Per BBTI 16 inch is about the longest you want. Peak velocity is 18 inch but you don't want to gamble with squibs.

[@TheExplosiveGuy]

I don't know about 10mm, but for a 9mm optimal barrel length is between 16 to 18 inches, depending on whether you're shooting standard rounds or +P/+P+. My Chaszel 12 gauge barrel adapter in 9mm has an 18" inch barrel and slings rounds on average 300-350 more FPS than a 5" barrel, up to 600 with Liberty Civil Defense. With LCD ammo the 18" barrel is making 800 ft-lbs of muzzle energy lol.

[@jameseroh6544]

Another KZbinr did a test with a very long barrel. The starting point was something like 6 feet. Then the barrel was cut down in increments as testing continued. The conclusion was the larger calibers had speed increases up to 28 inches. While smaller calibers like .22Lr, had speed increases up to about 20 inches or so.

[@geordiegeorge9041]

Only those who do not reload would say that a pistol/revolver round would be slower out of a longer barrel. This does happen to some .22lr rounds where the powder burn ends around 16 inches. I loaded some .38 special rounds and they were making 820 fps out of a 6 inch barrel and 1250 fps out of a 24 inch barrel. It all depends on the burn speed of the powder.

[@kirkboswell2575]

While it is possible to reach a point of diminishing returns regarding barrel length and bullet speed, under all "normal" circumstances a longer barrel will ALWAYS give higher velocities. The example that comes to mind is a 22LR with a 29 inch barrel (yes, there were some made). The 22LR achieves max velocity in 24 inches (assuming standard loadings). In a 29 inch barrel you will actually see a very slight drop in velocity when compared to 24 inches and "standard" 22LR. The real issue here is "how much difference?" And that determination is entirely subjective based upon chosen equipment. For ALL, repeat ALL normal choices and calibers a longer barrel will ALWAYS give higher velocities.

[@ValidSurvival]

Interesting insights on how barrel length affects velocity with 10mm rounds!

[@leonhart2452]

With some cartridges that use a case with a very small capacity, like 25 ACP, 22LR they don't contain enough powder to maintain a long enough burn time to gain much if any with longer barrels. I recall testing done and found that 22LR most standard loads with rifle barrels about 16” gets a complete powder burn and nets fastest velocity. Longer barrels gain a bit more velocity but when they get long enough, like in excess of 30" the velocity can be lower. Going from pistol barrel lengths of under 6" to carbine length of 16" you will get gains. At what case capacity these gains become substantial, I can't say. I have worked with the 44Mag in revolvers with 5.5 to 7.5 inches and a Marlin 1894. Most loads that get top velocity in the revolvers got 400 fps+ in the Marlin. Light loads not so much. Most load manuals have data for some handgun cartridges in both the rifle and handgun sections. Comparing them will prove to most how much you gain in the longer barrel. Some even have two handgun sections. One for regular handguns and one for single shots like the TC Contender and Remington bolt action. These sections have barrel lengths of 10" and 14". These sections also have many rifle cartridges shot out of these 10" to 14" barrels.

[@happycamper9300]

I would guess that most pistol caliber like the 9mm .40 and 10 mm would gain speed until about 10~ 12 inches. After that it will begin to lose some speed.

[@leonhart2452]

As WTW mentioned he wants to hunt deer with the 10mm. Some states this carbine he has is the only way to use a handgun cartridge to hunt deer. Here in NY you can't hunt deer with a handgun but getting the permit to have one is very hard to get. So to hunt with a handgun cartridge you need to get a rifle chamber in a handgun cartridge to do it. I think this applies to many states that say you can hunt with handguns but you need to jump through expecive and timely hoops to get the proper paperwork first. In this scenario the extra velocity can be an advantage. If you don't want the extra velocity you can hand load down to the velocity you want. For many shooting a small light weight carbine like the one shown is easier to shoot accurately in a defensive situation. Most any shooter can testify to this. How much easier is it to learn how to shoot a rifle than a handgun.

[@bussingwithbain]

Grew up in NY. Was shotgun only deer territory, but could use 357 or 44 mag pistol too.

[@marklaughlin08]

A longer barrel can slow down a pistol round, not usually though. It all depends on the type of powder in the case. Fast burning powder may fully burn half way down the barrel, to the second half of the barrel is just resistance as the gas expansion from the powder burn ended too early. Again, this is not typical, longer usually equals faster.

[@phillipedds8998]

Longer barrels definitely don't slow a bullet down, up to a point anyways, anything past 18 inches and you do actually lose velocity, though the shot is much quieter...

I have heard this discussion about 22 LR rifles. Not about the 10 mm. Apparently, 22 LR bullets are getting best velocity out of 16" or 18" barrels. (Not the 22" or 24" barrels, which have been popular in the past.)

[@bobellis1022]

In my opinion, the longer barrel will produce higher velocities. In 9MM, it's not as much because most 9MM ammo is loaded with a fast burning powder to help be more efficient in a pistol length barrel, so a 16" barrel will not deliver as much of a difference in 9. A 10MM cartridge is normally loaded with a slower burning powder so a longer barrel, such as your 16 incher will increase the velocity better. If you ever handload 10MM, you can tailor the round for that longer barrel and get even faster velocities out of it. Love the channel! Keep the videos comning!

The original Norma loaded ammo was pounding the Colt Delta Elite to pieces. Cracking frames etc. Get some dies for the 10mm, roll out some of your own ammo.

[@jamieeakin1383]

Used to have a KelTec folder in .40 S&W. I discovered that the heaver bullets (180gr) did not gain a lot of velocity from the 16” barrel compared to the G23. There was some, so technically it gained fps, but not enough to be considered a big difference. Lighter bullets (135 or 150 gr.) did gain more, but I do not remember the numbers.

That's proof why we can't predict what one load or caliber will do when we change barrel length or ammo. 👍

Exact results I expected

[@dannytravis7118]

From what I've seen. In 22lr 32 acp 25 acp a longer barrel does hurt velocity and even 380 acp is pretty sensitive to barrel length. For 380 acp 3.50 to 6 inches is about the best it can be. At 7 inches and more the barrel does start creating drag. But in calibers like 9mm, 10mm, 45acp they all tend to do well with barrel length up to 16 inches. Run that test again with a 22 inch or 24 inch barrel and see if don't start slowing it down some. Sometimes there is too much of good thing that starts to hurt you.

A long barrel helps with slow powders that can keep pressures high over the barrel length. Fast small powder charges can indeed run out of gas literally, before the end of the barrel.

[@MichaelKMorris]

9 and 10 mm are optimized at about 9 to 10 inches with little gain after that. 357 and 44 mag keep gaining to about 16 inches similarly. Super long barrels only help high velocity rifle loads...short barrels defeat them. A hot 10mm out of a 10" barrel has more energy than a 300 BO out of an 8" - you lose half or more of potential energy going that direction.

[@budlite8207]

I know a 22lr will slow down after 18" or so. Small cases, just not enough poop behind them. Target rifles with long barrels and open sights Have like 6" of open barrel at the end, which just lengthens the sight distance.

If .22lr can profit from a longer barrel, anything should (except maybe stuff like 6mm Flobert). Yes there is a drop-off point where longer barrels don't add speed but reduce it, and it's around 18" for .22lr (someone tested it a few years ago).

[@Themeshoots]

Thanks for the video. I'm sure the longer barrel helped but going from a cheap pistol to a carbine is extreme in your analysis. The power was probably all burned up many inches before you hit the 16" mark. My guess is that something between 10-12 inches would be optimal for this cartridge. Cheers.

Anyone who actually went to science class in school knows that the longer the gas from the expended cartridge has to burn, the more force it will generate. "Physics don't lie..." (Yes, I went to English class, too). Hey, bud, I have a 1911 by Alpha Foxtrot (custom maker from Duluth, GA) in 10mm and it's an amazing machine, a 10 carbine would be terrific. I have a well massaged (by yours truly) Glock 21 pistol *and* a second G21, also reworked, attached to a Mech Tech carbine upper (no registration, it's just an upper! 😊) in M4 configuration in .45ACP and it kicks butt. Think of a modernized Tommy gun w/27rd. sticks. Anyway, it absolutely gives more burn time and faster speeds than the 4 3/4" barrel. Unless you have so much barrel fouling that it's impeding the bullet, there's no way it will give a slower speed. 😊 The reason a lot of people never get the speeds listed on the box of hunting/rifle ammo is because a lot of companies use a 26" barrel for their testing and rating data. Them people use an 18/20" barrel and say the ammo is crap cause it never hits the listed speeds but, it's not the ammo, it's the shooter's choice of firearm.

[@chrisjones469]

Longer barrel length generally means higher velocity in everything except perhaps a .22lr. That said, the marginal cost of quadrupling the barrel length doesn't yield a proportional increase in velocity. If you take a .308, for example, and cut it down to 5", you're going to see a dramatic loss in velocity, and a much greater proportional difference. This is because pistol powders are generally faster burning than rifle powders.

[@Thousand_yard_King]

The speed of the bullet coming from the barrel is all dependent on the powder charge that was used when it was loaded. The type of powder and the quantity of powder. Because the right right powder and it will still be burning at 16 in barrel length

I boycott underwood. They blocked me on Instagram

Cooper's original specification was 200 grains at 1,000fps (very close to the .40 S&W we eventually got). Norma's load was 170 grain JHP at 1,300 or a 200 grain at 1200, they insisted on pushing the capabilities like that as a marketing gimmick. I consider it a big factor in dooming the round to obscurity because it lead to excessive wear on pistols, overbuilt pistols to compensate, and excessive recoil.

Had this conversation with an engineer years ago I had saw an article years ago where they did that with a 5 inch barrel out of a 45 ACP and a Thompson with a 16 inch barrel the were using fmj, hollow points, and plus p rounds in the longer barrel did produce faster with the engineer I was talking with says what's the longer borrow you will get faster velocities to a certain point because then if the barrels just saved for an example 24 inches long using a pistol cartridge the propellent will burn out then you would get that it would slow down

I have been hoping someone would come out with a lever gun in 10 mm 14 inch bbl.😊😊

[@user-fj7vm9fz2h]

Have they gotten their Powders correct yet? Burning faster or slower I think would mean more.

Man those cicadas are somethings else!

[@WHOTEEWHO]

So loud

[@beardo_M.D.]

You should also compare a revolver. They are even slower due to cylinder gap pressure loss.

[@BikerDash]

They make those rifles in 9mm? I was thinking that'd be the least expensive thing to shoot above .22lr.

Send me that TNW ASR 10mm with one of the mags that came with it and I will repair it. I am a gunsmith in WI. I will pull the magazine catch/release, file off the upper side of the catch block, recoat it for rust prevention, reassemble and test, then ship it back for free.
