How do you fix a bulged gun barrel?
I have different barrels with different problems.
Shotguns, pistols, revolvers, and rifles. Do you make die by making a hole in a block with a boring bar, heat up the barrel and pound it through? |

Using proper fixtures, unscrew barrel from action Cut in half to prevent reuse and deposit in trash can. Install replacement barrel. I'm not trying to be funny here either. Maybe, someone that really knows what they are doing, can repair a slightly bulged barrel. But I would never knowingly buy nor shoot a firearm with such a 'repair'. If you insist on trying to repair a bulged barrel, for your family's sake, make sure your insurance has good coverage for ER visits, and that your life insurance is paid up... Jon It really depends on the type of bulge and the extent of the bulge. I had a guy bring me a MINT S&W 38-44 Outdoorsman some years ago, that he had squibbed 5...(5) 158gr JHPs into. I thought it was only the cylinder..and dropped a rod down the barrel to drive the bullet back..and it only went in 2"...... To make a long story short..he decided he didnt want the revolver as it wasnt "mint" anymore, with a .050 TIB about 1" long just in front of the cylinder release housing. So I wound up with it and have shot it sucessfully for at least 15 yrs so far. Very accurate, a pleasure to shoot. Der be Bulges..and then there are bulges. Gunner -- "You can have peace.

Well my concern was the possibility of either over compressing the bulge, or getting adjecent deformation into the bore that might cause the bullet to stick at that point.

I can't imagine it's a good thing, but surely it happens often enough that manufacturers would design barrels to withstand the abuse - if not unscathed, then at least in one piece. Bear with me - my firearms knowledge is all 4o+ years old and limited to small-bore target shooting.

Sounds to me like Gunner just removed the stugs , didn't try to "repair" the barrel . Jon's first assessment to rebarrel was right on the money . Only thing I might do different , and it would depend on where the bulge was , would be to use the undamaged portion for another firearm - perhaps a pistol if the caliber was appropriate . I've always wanted another .222 pistol ... a bolt action , the first one was a Contender . Still got ammo from that one , too bad I needed groceries more than I needed the gun , but kids gotta eat . -- Snag Learning keeps you young ! |

Jon The bulge wont grow if you keep your rounds within accepted pressures..and the bullets wont stick if you keep your bullets above the proper minumum. Id not recommend using hollowbased wadcutters as mine tends to build up a smidgon more lead in the bulge when I was experimenting, but other than that..cast or jacketed..it still shoots very well. And Ive run at least 15,000 rds down that barrel. Shrug Gunner -- "You can have peace. Or you can have freedom. Don't ever count on having both at once." Robert A. Heinlein |

But a revolver has a better chance of getting away with this as the cylinder gap will allow the pressure to bleed off. But certainly not always. I've seen dozens of pictures of firearms with blown up barrels. Sometimes it's just a bulge and a short split, other times the barrel is really peeled open. This is really dangerous with a rifle or some shotguns where the stocks can be blown to splinters. 30+ years ago I was working at a welding shop in the Bay Area. Some company that did testing of some sort was moving out of the bay next door. There was a number of cylinders of steel, best I can recall, approx 12-14" dia and maybe a bit longer. Each end was machined very much like a cannon breech (I'd guess, haven't seen many cannon breeches up close...) and had an approx 1.5-2" dia hole thru the center. Anyway, every one of these was split down the side. The split wasn't very wide, but considering the thickness of these things.... I didn't know jack squat about firearms at the time, but had been around enough heavy fabrication to have at least have a sense of awe over what forces were at play. Google search on 'blown up barrel', images: http://www.google.com/images?hl=en&q=blown up barrel&um=1&ie=UTF-8&source=og&sa=N&tab=wi BTW, this conversation is conjuring up images of Bugs Bunny sticking his finger in the muzzle and Elmer Fudd getting a face full. Myth Busters tried test this. Conclusion was it's a really really bad idea to stick your finger in the end of the barrel... Jon |

It talked about removing bulges and rings. Procedure was (originally published about 1920) for an experienced barrel straightener to hammer the barrel on a vise to remover all the bulge, then ream to size. CarlBoyd |

"Support Your Local Sheriff" - James Garner as sheriff, Walter Brennan as bad guy patriarch. Brennan storms into Garner's office, pulls his Colt 45, and demands Garner release Brennan's kid. Garner sticks his finger in the end of the 45, and Brennan cools off like he's been doused with water. He says, "If that gun'd gone off it'd a blowed up in my face!" Garner says, "Well, I don't imagine it'd've done my finger much good." BTW, very good movie, highly recommended. Joan Hackett as the love interest, Harry Morgan as her dad. ;-) Cheers! Rich |

Nah, Elmer would stick the gun down the rabbit hole, and Bugs would bend the barrel around to point at Elmer's ass through the rabbit hole right behind Elmer. ;-) Although, I'm not claiming he's _never_ stuck his finger in the barrel, just that I've never seen that particular action. :-) Cheers!

Of course, with a gun, there are sometimes
moments when you can use the gun to get food. So, it isn't always a "gun, versus food" decision. -- Christopher A. Young Learn more about Jesus www.lds.org .. "Snag" wrote in message ...

Just for me, I'd replace the barrel, or scrap the gun. YMMV.

I'm about as cheap as anyone, and have been known to spend totally stupid amounts of time fixing things 99.999% of the country would throw away. But there's a time and place to try and skimp. The risk of blowing off fingers, losing an eye or two or worse, far out weigh any savings on this one. IMHO... Jon |

Do you make die by making a hole in a block with a boring bar, heat up the barrel and pound it through? I've seen some old books recommending various fixes for bulged shotgun barrels, I wouldn't do any of them except shortening. If it's near the muzzle, you can always shorten it unless it's below the legal limit. Anything else you should probably replace if it's bad enough or just keep using it if it's accurate enough after removing the stuck bullet. There's no way to reduce a bulge in a centerfire arm short of replacing the barrel or cutting out the bulge. You can shorten a revolver barrel, usually, semi-autos are easy enough to find replacement barrels for. Bolt actions are easy enough to rebarrel. Best advice is to pay attention to the gun when shooting, if you shoot and something feels/sounds/smells odd or not normal, STOP. I had a blooper once while hunting, had a second round all chambered and ready to pull the trigger on a rabbit. Something told me not to, went back to the truck and poked a rod down the barrel. I retrieved the whole front section of the first shotshell, it had separated right ahead of the brass head and gone about half-way down the barrel. A second shot probably would have removed my fingers. I caught up with the rabbit afterwards. No blooper that time... A bulge means the metal is stressed beyond the elastic limit, even if you manage to pound it back down, it'll be a weak spot. If you stick a bullet, use a brass or bronze rod that fits the bore to push it out. I've seen folks recommending dowels to do the job, those will shatter and wedge the works even tighter, DAMHIK. Steel is likely to gouge the bore unless really closely fitted and polished, anything really undersized, ditto. Aluminum may work, may also bend if it's the usual hardware store bubblegum extrusion. A series of stuck bullets will usually have to be either drilled or drilled and pulled, usual method is a steel tube to line the barrel and then a close-fitting drill with extension brazed on, if needed. Pounding on jacketed bullets will just wedge them tighter. Best thing is to drill and then use a ball-puller. Stan |

The usual technique was, if the bulge was far enough up the barrel, just cut the barrel off and install a new sight, or adjustable choke, as the case might be. If not, just remove barrel and replace. I never met a competent gunsmith that recommended attempting to repair a bulge. A dented shotgun barrel, yes. But not a bulge. Cheers, John D. Slocomb (jdslocombatgmail) |
