I've been spending hundreds of dollars a pop every time I need a new Krieger barrel for my service rifle and then some guy takes 3rd place(with a perfect score) in a match with a rifle barreled with a piece of rebar and the scope is epoxied on.
 I feel like I've been had.  The article is in this months' issue of Precision Shooting. |

Just might be true... If you were good enough behind the trigger, and wanted to blow some minds it would be fun.
Nothing wrong with the epoxy for a range gun, as long as it holds.

How exactly does one get the idea to turn a piece of rebar into a rifle barrel?
Pretty neat nonetheless. |

The article is in the latest issue of Precision Shooting. First off It is not rebar. 2nd There are only around 7 Pratt Whitney Cut Rifling Machines in the United States. All of them owned by custum rifle makers like Obermeyer, Kreiger, Mike Rock and so on. If he cut rifled the barrel he is one of those guys. Most bench rest shooter agree that you can make a good barrel out of crap steel with cut-rifling as it does not work harden the barrel when machined. |

So realistically its probably not the worst steel you could use, BUT rebar is made cheaply and in large quantities with less QC than barrel blanks are. So it probably wouldn't last very long (maybe a few hundred rounds) before you got pretty bad throat erosion, but it wouldn't be the worst thing you could possibly do.... I think the guy is a fucking genius for thinking outside the box like this. Why the fuck not, right? Good on him 
ETA If you had a broaching cutter and a lathe with a timed pull arm (for cutting threading), its theoretically possible to cut rifling (one groove at a time) and as the guy said, on ten thousandth at a time is about what you would do. |

By watching an episode of 60 minutes back in the early 1990's when they did a segment on Kyber Pass firearms manufacturers. My memory is fuzzy, but I do remember them filming some guys using rebar to make rifle barrels. The rifles in question at the time looked like copies of Enfield No.1 MK III's. |

I don't believe the caliber was listed for this rifle but they are shooting soft lead bullets in the 1300-1500fps range. I'm wondering how much better or worse a rebar barrel would be from a barrel made 150 years ago. |

Only .22 rimfire rifle barrels. Carbon steel erodes with centerfire pressures. Rapidly. Rebar can be mild to medium carbon. Fine for rimfire.

Have you ever seen a rifling bench that is operated by hand, under armstrong power? Tom Bodnar was shooting a Yost action. The barrel is chambered for 32RKS shooting a 320 grain bullet. The barrel was rifled by Tom Smith with a gain twist (his signature) but I haven't seen a mention of the actual twist. |

Quoted: He probably tempered it. The accuracy from that set up is from all the elbow grease and ingenuity put into it. That is how you polish a turd. Hardened, then tempered. Only if it is 0.35% carbon steel or greater. Hardening that dimensioned bar would require 0.50% carbon which is rare. Tempering reduces the hardness and restores toughness. |

Carbon content is controlled by forging steel blister until the carbon content is correct. Lots of art, little science. Rebar of today is far higher quality. Most comes from mini-mill plants which use scrap steel. Alloying elements (Cr, Ni, Si, C etc) are all burned out by oxygen lance, then specific alloying elements are added to the heat (charge in the arc furnace) and then the furnace is tapped into the ladle. From there, it goes to strand casting, usually 4x4 and larger "strands" which then are processed by hot roll/slitting/drawing. Remember, the steel used in the Titanic was Bessemer converted, meaning air was used to burn the carbon out. Nitrogen contaminates steel, making it brittle at colder temperatures. Modern low carbon steels don't become brittle at -20 F temperatures. |

I think modern rebar has reasonably rigorous control these days. If I remember tomorrow, I'll see if I can scare up a spec, that will lay out the chemistry and allowable defects. I think it's hilarious. Now people will be scouring the countryside for old Ford axles and other assorted junk. |
