No. It was made of mild steel. Forged. You cast iron. Not steel.

A 45 generates the same psi in a far shorter barrel. As the smokeless powder burns, the goal is to keep the pressure the same during the bullet travel.

A 4570 generates all it's power at the moment and the few moments after ignition. It is a fixed charge of pressure like an airgun. As the bullet travels down the barrel, the volume is increased and the pressure DROPS. How do you not understand this?

That's the nature of black powder.

"For the Springfield Model 1873, the barrel was manufactured to be milled out at the rear to accommodate the trapdoor breechblock mechanism. This involved converting existing percussion rifled muskets by milling out the rear of the barrel and inserting a new barrel liner to fit the .45 caliber round. The barrel was rifled to impart spin to the bullet for better accuracy."

The gunsmith master and his journeyman heated a long piece of wrought iron in a forge.
  • First the barrel was fashioned from flattened wrought iron that was hammered and wrapped around a steel rod to prevent the tube collapsing. When the rod was removed, the result was a hole in the center that would be smaller than the finished hole.
  • Secondly, the hole was enlarged, cleansed, and polished through precise boring to fit the caliber of a particularly sized shot or bullet.
  • For rifle barrel, it required the additional boring of grooves along the inside tube called ‘rifling.’ This set the bullet spinning as it was launched. This stabilized the shot to assure better accuracy.

How Colonial Gunsmiths Forged Musket and Rifle Gun Barrels

From a flat bar of soft iron, hand forged into a gun barrel; laboriously bored and rifled… in a shop long since silent, fashioned a rifle which changed the whole course of world history. …

Forged not cast. Black powder not smokeless. Why are you still arguing?

This article has zero mention of springfield rifles or the 1873 but you pasted two completely unrelated quotes together because youre mad you got exposed for not knowing what youre talking about and now youre trying to lie to look good

The article shows how musket barrels were made through forging. The Winchester company listed on their website that Most of the early barrels were forged from one piece of stock.

I don't know where you got this information. But the barrels both conversion models were relined with forged barrel liners. It says so in the article.

English made crucible steel a.k.a. "cast steel" was used for barrels as early as the 1820s. Remington usually takes credit for introducing it, but this isn't true. They should, more properly, say they popularized it. All military barrels were made of iron until the introduction of the Trapdoor Springfield. Bessemer steel doesn't come into production until the 1850s, but not, as a rule, here. In fact, as late as the 1840s Springfield was importing all its steel from England and Germany and lamenting the fact that no good steel was produced in America. From about 1855 on even the iron used at Springfield was imported because no American iron could be used reliably with the new barrel rolling & welding machines introduced to build the M1855 series of arms.

A civilian rifle barrel from the mid-19th century could be either but if made of steel it will probably say "cast steel" somewhere on it. (It was more expensive than iron, thus sellers wanted people to know what it was). A cast steel pistol barrel is much more likely than a rifle barrel as they could be drilled. Full length barrel drilling for rifles wasn't developed until after the Civil War... the earlier barrels were drilled as short blanks and drawn through rollers over mandrels to lengthen them. (They are, effectively, seamless DOM tubing). The term "cast steel" does not mean the barrel was cast. Its a reference to the method by which the steel was made.

And no barrels were not made with cast iron. iron is too brittle you dolt.
 
The Springfield Armory would make its muskets with wrought iron, and even when it converted them to breechloaders in 1866, and had to sleeve the 58 caliber muskets to .50, the barrel liners were specified as either iron or steel. Only in 1873 would they move to making steel barrels for their guns. And W.W. Greener ( son of W. Greener) would be one of many makers of fine shotguns who would have pattern-welded barrels, AKA Damascus, that would be woven weldments of iron and steel with a thin steel liner.

US standard rifle used to be the 1873 Springfield using a cast iron barrel firing 45-70 black powder rounds at 20,000+ psi

Pressure of a 45acp maxes out at around 20,000psi, is only around 17,000psi on many rounds
