I had a chance to visit the Sabatti factory in Gardone, Italy. This company is one of the very few who manufacture barrels with cold forging method. This method is capable for manufacturing extremely durable barrels with very accurate dimensions. The technology was invented in Germany/Austria just before WW2, but it is still one of the best methods for making an accurate rifling and bore. Enjoy the trip!
Please tell your hosts at Sabatti that we all appreciate them letting you film this. They have any amazing factory and it was very interesting to see how this is done. Rifling is always a bit of a mystery because the major manufacturers never seem to want to divulge their methods. Thanks again for sharing this with us.
Well said!
Thank you very much for showing me how the barrels for my custom rifles have been made they preform as well as the loads I have developed for them. The Coyotes don't like them very well, they run out to a distance they can't normally be hit stop and look back at you for maybe two seconds long enough to get a hot off if you're ready, that's the last mistake they ever make.
I've seen button rifling methods, but never hammer forged.

Go to BSA UK air rifles and you will see a far clearer picture of cold hammer forged barrels being made the best of the best
As a machinist, this process was very interesting to see!
Thank you for the video.

As someone training to be a machinist it was also interesting :)
The best video of hammer forging I've seen. PS: Never mind the trolls, your English is excellent.
Is button barrel below cold hammer forged?
@@Pippinm7 If by "below" you mean cheaper, then yes. A button rifled barrel is made with easy tools in a few seconds from a drilled blank. Hammer forging requires far more complex machines. The benefit is a change in material properties due to hammerin. There is this myth of the steel becoming denser, which is no more then a myth. What happens is a change in the material structure, creating internal tension, which in turn leads to harder and tougher material.
@@peteraugust5295 thank you!
so its called hammer forged because the rifling is done with something like a hammering machine?
@@barfylord8453 The "negative" mandrel is what the hammers are beating/squeezing the entire piece of pipe (unfinished barrel) down onto. The process is akin to squishing larger lump of play-doh through a smaller tube, with a hard rod inside it. Steel can be formed, it just takes immense pressure (the hydraulic hammer). As that machine hammers radially around the barrel, the barrel is slowly pushed through the machine, rotating as it goes. The result is uniform exterior and the internal mandrel with the rifling travels along with the rotation rate of the rifling from one end to the other until the entire length has been hammered.
It's really the same as other hammer forging processes at a steel mill, the goal is to re-align metallic grain structures into a uniform and consistent direction which significantly increases strength, hardness, and other properties. Steel has microscopic grain. It's like the difference between a heap of random scrap metal, and that scrap metal welded into triangular lattice structure. One is shifty and weak, the other is stiff and strong.
Some hammer forged barrels are left with the hammered surface on factory rifles. Many have additional finishing removing those visible hammering spiraled ridges from the outside surface before moving on (receiving cerakote or bead blasting or some other finished surface).
Well that was an eye opener for sure! Amazing video. Thanks to Sabatti for letting us see this. They must be very proud of their manufacturing processes and it was amazing to see the 21st century rifling machine in operation. I could not believe how much the barrel "grew" during the hammer forging process on a cold piece of steel. It looked to be about 9" or 225 mm. Crazy!
It's useful to know that one of the reasons for the compression hammering at the rifling stage is to prestress the material, thereby reducing deformation due to the increased stiffness (Young's modulus) and also increasing the loading that the barrel can take. Though this is rarely an issue for civilian applications.
Don't know about Sabatti but I have owned several muzzleloaders from Pedersoli. Fit and finish is ALWAYS excellent and they are ALL superbly accurate. I was pleasantly surprised. The first deer rifle I got when I was a kid (1967) was a surplus Carcano, mostly because it only cost $25. It was about $5 worth of rifle...Then I got into SPorting Clays back in the late 80s and a friend bought a Beretta. long story short, I am very impressed by every modern Italian firearm I have seen.
Reminds me of watching the Swiss make their watches in-house. Shop tours are always among my favorite things to see. A place that won't give a factory tour is usually one that is embarrassed of their processes/technology or otherwise has something to hide (such as a huge amount of outsourcing).
Or simply has trade secrets that they don't want to share.

That was excellent! I've been trying to find "How it's made" videos on gun making and this is the best one so far. Most have the narrator on the shop floor and you can't even hear them.

I understood the basics of barrel making but have never had it explained with such visual clarity as this video.
It sure gives me a better appreciation for the methodology in the job.
Thank you for the presentation as well as to the manufacturer in letting you see their processes.
AMAZING!!
As an aside, this is my FIRST time seeing your video and posting but rest assured that I have SUBSCRIBED to your channel as you are a very credible information source. Thanks again!
Not all barrels are made this way. In fact most barrels are not made this way.
I love your channel capandball! I am from Maine in the US, and my job involves drilling metal like what is shown in your video. However we don’t do gun barrels anymore but we used to several years ago (including putting the rifling in the barrel). As someone who loves history and firearms it was interesting to see firsthand how it is done and then watch this. A machine that drills six barrels at once, I wonder how they kept them all within tolerance!
I am a machinist and used to work for Eaton here in Oklahoma and I ran these huge drill press machines called NATCO’s and they would drill out the motor parts that I made. Each of the 2K parts got drilled two holes on both sides. The 4K machine did the same only had 4 spindles with dual drill bits. The 5K machine had 5 spindles with two drill bits a piece. So each spindle would drill at the same time. We did batch testing with a go no go gauge. Every 20 motor parts I would check 5 of them. Most of the time they were good to go. If it got out of spec I had to change the tooling out and set the bits to the correct height. That was a pain in the rear!
Zastava and SAIGA use cold hammer forging also. Neat technique
Arsenal, FN are among them as well. All make great barrels.
Thankyou for showing us your film. You have great skill, knowledge, commitment and passion in your work. You deserve everything great that comes your way.
Great Video, thanks much. A rare insight into how it is actually done in a production environment with older as well as modern CNC machinery.

I have a book here by Ian Skenerton about each company which produced SMLEs during the Great War.
The BSA factory still emloyed blacksmiths to rough forge all the major components to the rifle, and then these pieces would go to the machining shop.
It's amazing to think this was done during a war with so many 303s made.
This was an excellent video. Thank you for it. I had no idea that much went into making a barrel. Those shotguns were beautiful at the end. I bet the skill on their workers is unmatched.

Incrível a criatividade do homem para melhorar os métodos de fabricação.
Bravo! A lot of information into a short video. So cold forging work-hardens the whole barrel while button rifling only work-hardens the bore. And cnc machining is why some very inexpensive firearms can be very accurate.
the quality of any product is only as good as the quality control department.
The steel is _already hardened._ That's amazing to me. That hardened steel can move that much. It's so hard to even drill hardened steel... I can't imagine how it stretches and forms that much, especially without cracking. Amazing.

You can trust the Italians. They are very good engineers. Excellent factory. Very Skilled.
+Crobular I I'll buy that. I love my Faustie
+Crobular I yes they know their art, building, and devotion to things, and know hot to not rush stuff and do it the best can be, look at the old buildings in the city of rome, its crazy how for as active sismicly italy is with the vulcanos and earthquakes that anything stands but some new buildins are put right to pre empire age buildings and you cant tell a differance, they know how to build, and its crazy but the 1000 year old building the pantheon that was the largest monolithic dome build untill modern times, never cracked and its older the christianity, yet many of the italian churches did not even have solid domes and they cracked at the base like the one on St Peters in the Vatican, they put chains around the dome to help with the compressive forces of gravity, the italians know how to make stuff well, and have been doing so for a long time, but mechanica, I go with austria, germany, switzerland, and usa and canada, as many old families the know the europenal enginering and mechines brought that to america, and had the drive to make it many times over the last 200 years to rivel that of the germans and swiss, and you got to give the japanese and indians credit too, in art and metal blade making, japan has many that are very regemented and soo devoted to the art its like a religion, they also have taken many things mondane and made the meditations, like tea ceremony, or shooting the bow in kyudo.
+Crobular I They're exceptionally good at making shotguns and pistols. They also have good local harvested selections of marbled walnut to make fine stocks and fore ends.
+Crobular I Anyone that has read "Desert Fox" or "Tiges in the Mud" by Otto Carius, or even Panzer Commander by Hans Von Luke, knows that the italian tanks were far less superior to the German tanks, but not because the Italians didn't know what they were doing. They simply didn't have the Economy that Germany did. You will also know that everyone who fought along side the Italians, knew that their Engines were FAR better than anything else on the battlefield in the early 40's. The Italians had long since mastered the ability to engineer great engines (look at ducati, lambo, ferrari) and other great Italian Cars. Their engines are solid. Nothing wrong with Italian engineering. They just weren't up on the building of the actual TANK before WWII. They have long since caught up and the C1 Ariete is a FINE tank.

Hi...
You're right, you're among the few who know the real facts ..someone instead should look at Wikipedia who were Barsanti and Matteucci, the inventors of the internal combustion engine, which unfortunately for them they did not have the money to continue paying their patent..is an Italian tradition to know how to do things but do not have the money to market them :) or to be blowing the patent by those who must protect it and sells it to others, as in the case of the phone, Italian invention of the '60s years, greetings from Italy...
Μπράβο Ιταλία.....!!!!
I'm not even starting about people being shot with Sabatti guns, they're being shot by other people.
When a few years ago friends in the Sabina region north of Rome invited me to help harvest their 1 hectare of olive trees I was so delighted. The work took a week with 5-6 people working 8 hours a day but it was wonderful to do in a beautiful valley with hedgerows, patches of woodland, meadows etc., it was the Italy you dream about in cold, wet Holland. Then I noticed there were no birds, especially no singing birds, didn't hear a bird's song all week being outdoors, I could't believe it. When asked my hosts explained birds are being hunted all the time by local hunters who have the right to enter anybody's property to do so, and will hunt even the smallest birds. There are some birds left but they have become so shy and elusive that when you maybe could hear them at dusk and dawn you will not see them. We are talking about big men with Sabatti shotguns hunting small delicate singing birds weighing a few grams for the supposedly culinary reward of consuming them, often migratory birds that have nested in countries that fiercely protect these small wonders of nature. Congratulations Italy, congratulations, Sabatti!!!
I never knew that hardened steel could be cold hammer forged,
The fact that any level of 'hardened' steel can me essentially 'molded' by this process is amazing. My Steyr hammer forged barrel rifle is incredibly accurate.
Enjoyable and educational. Thank you, Sir
I enjoyed seeing the other process of making lands and grooves. Thank You
Thank you Mr Sabatti!
I believe Steyr leaves the rifling marks visible on the outside of the barrel. Beautiful finish. With a controlled internal bore taper decreasing towards the muzzle, the result is an unbelievably accurate barrel.
They do on many. The Mannlicher Luxus series have them for about 4 inches ahead of the action, beautifully polished and blued. Very striking appearance.
If the barrel blanks were truly hardened before processing, they could not be drilled, reamed, or hammer forged. The hammer forging itself imparts work hardening, and much strength.
I would have liked to see how you get the insert out.
he means they are made of hard steel, it certainly is possible to apply any of those processes, it is just more difficult to do so.
Gun barrels aren't hard like knife-steel hard. Milspec M16/M4 barrels call for a Rockwell C hardness of 28-33 after tempering. Likewise, carburizing doesn't make a thing impossible to machine. I do it at work all the time.
Probably just spin it out
Interesting
Thank you for the tour

Great video... Sabatti makes good weapons. I have to say that the best way for accuracy is to do the rifling is by cutting... forging puts stress in the material that affect accuracy when barrel heats up.... every user must decide how accurate he wants his rifle for his use.
Jacques Shepperson The other difference between hammer forging vs. cutting is that the barrel is work hardened as it is forged, making for a barrel that will not bend as easily. Not important in a marksmanship setting, but all the difference when dragging the gun around in a hunting setting.
Best video I've seen on the Cold Hammer Forging process

Very good video , very interesting process of gun barrels making .Sabatti is a name to remember for me .
I must search if you have something showing how before these machines, it was done. That fascinates me as a budding blacksmith.... I saw pistol barrels done a bit, but never a long gun.
So they precision ream a bore, then turn the OD to spec, and finally, they slide a reverse image mandrel into the bore, and hammer forge the outside of the material until it's to OD spec, and end up with strong then eff barrel, (I got to picturing the complex alignment of the grains in the steel as the process was described. THAT is some seriously clever inverted/inside out thinking methodology.
I've been contemplating building a hammer forge just to compete with my new neighbor across the street. He's a professional drummer who bought the remodeled house, and had a not nearly sound-proofed enough studio where the old garage was. I'm working on the math of how much weight can be lifted as the hammer with a 4' diameter, 1,000 pound flywheel. (some creative gearing and it could be run with a 1hp 240v motor, or a scavenged treadmill motor.)
It should be for a good 'pop'. LOL Just haven't figured out what to make the anvil base from. i'm kinda leaning towards find something at a locomotive salvage yard, (as close to Portland, OR, as possible, cause the freight weight's gonna be up there...
I'm looking for that 19th century steel mill 'clang', with the appropriate 'ground effect vibe'. HaHaHaHaHaHaHaHa! I wanna make his cymbals vibrate on every strike. Then, I'm gonna shop for a nice old, use iron worker... it is suburban war!
(The following passage was heard in the narrator's voice from public broadcasting's Frontline as I wrote it. Let me know if you hear the same as you read it.)
"He was a conscienscious artist who religiously practiced every day, for many hours. A new member of the neighbor, he was well liked by all, and his dedication to drumming was admired by ALMOST all.
After his studio went silent one day, he was found with drum sticks where they should never be inserted."
GeoD
PS
I'm joking. Not about building the hammer forge, or getting an iron worker, just about it being to compete. I actually like the new neighbor, he's got some good color on his arms, and he's fairly cool. I don't actually mind the incessantly repetitive practice patterns he drums one bit.
That is really cool, I've seen these giant machines before in pictures, but I've never seen how it works before.

+Able Fox The factory was too loud, the accent wasn't Italian enough, they don't like the colour of the shirt, weapon producers are murderers. Take a pick, some people vote videos down for anything ;)
A couple of misclicks might be among them aswell.
I highly doubt there is some conspiracy where anti-gunners are going around and thumbs downing any videos about guns. I think what is more likely is that people are just spoiled by the detail and high production value of shows like "How It's Made", and were disappointed in this.

Also, the nipple ends on the blanks going into the GFM machine are HUGE! The front sticks way out and the rear looks like it doesn't have much chamfer at all. Surprising they don't have more loading issues when the chuck head advances. Maybe their drivers are just cut very VERY steep to compensate.

The firearm industry if like many businesses are going to use whatever methodology makes the most consistent profits. Where if minor accuracy issues exist because an automated process can make 4 barrels with what are essentially neglible inaccuracies, in place of one barrel that is extremely nearly perfect. Then other short cuts that saves money or makes money naturally, but it can get radical sometimes. For anyone unaware.
With this is in mind, what method creates the finest quality barrel? forging, rolled steel, direct casting, what? Automation can not be outperformed granted. But to make the best quality of barrel, reliable, ultimate accuracy and longevity, etc?
I'm thinking one could be forged at home if one has the knowledge and basic facts of barrel making.
