How hammerforged barrels and riflings are made 

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

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).

As someone training to be a machinist it was also interesting :)

Or simply has trade secrets that they don't want to share.

Not all barrels are made this way. In fact most barrels are not made this way.

Arsenal, FN are among them as well. All make great barrels.

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!

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.

Just imagine if anything bad were to happen to disrupt society. And this applies to all manufacturing, how many people would even know how to run these machines that keep our world going.

@@flat-earther No offense mate But if you look at the angles of the stars in relation to the earth its impossible The Earth is a globe For instance, you cannot show me a picture of polaris and the southern cross in the same picture Not on Earth, Not in space Hell, you would have to travel some 1000 light years Almost leave our galaxy to capture them in the same picture Think of that They are in opposite directions

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

@@flat-earther And exactly what does that have to do with the video or my comment? Also, if you want to push idiotic theories, it might help your credibility to at least use proper grammar. But not much of course.

@@Golgafrinchamdent No relation but random suggestion. If you want tell me how to write.

@@flat-earther Again, your meaning is unclear because you cannot express a cogent thought -- "If you want to tell me how to write." It goes a long way to explaining why you fall for "flat earth" theories... you're just not very smart.

+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.

+JackG79 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...
