I use a band saw and clean it with small hand files but you can do it with a miter saw and metal blade and just clean it up with a small round file. I am sure there are a ton of ways to do it, all that really matters is a good straight cut.

Modern metal miter saws use a carbide blade and will cut very cleanly. Time to upgrade. Makita
Otherwise, use a band saw and clean it up with files. Be prepared to braze the barrels together, it is possible they aren't attached where you are going to be cutting. |

I have used a angle grinder with a thin cut-off wheel for several shotgun barrels and it works well. After the cut the ends are dressed/squared up with a file.
Filling the rib between the barrels is a pain. I made a dam out of steel wool then filled the rest of the rib with solder. Once that was done I cold blued the affected areas. |

We always used a hack saw. Very slowly. Then sweeten it up with some files, sand paper, and steel wool. Touch up with cold blue

And works fine for a side by side, since your using a live center with pilot in each chamber, one at a time. So my low down to shorting a O/U barrel, Mill to make the initial cut square to shorten the barrel, face cutter and watching DRO to make both barrels the same lenght after face reamiing, solder to re solder the center section void between the barrel, then re-drill and tap the front site bead channel to reinstall front bead. From there, cold bluing to touch up the worked surfaces, including the solder used to refill the center void section of the barrels. If you don't have a lathe, then the end reamer can be used in a drill instead. |

Any reason he couldn't use a mill with something like an end cutter?
Never tried it on a SG barrel, but seen it done to a cylinder sleeve in a machine shop. Walls not much thicker than a good SG barrel. |

Walls not much thicker than a good SG barrel. Getting the muzzle squared to the bore is the important part and using the piloted facing cutter that Dano523 shows in the video above is the easy way to do it. |

OP, you can rent the facing tool Here, at 4D tool rentals for $24 If you don't want to buy.
I have no association with them other than as a customer, service and tools have always been A+ |

I have done it. A miter saw with a metal blade will work. Shotgun barrel steel is fairly soft.
Just need a long wide metal file and a square to even it out. If you are going for minimum length start out at least 18 3/4. By the time you dress it up you may be near 18 1/2. And you may need to braze or silver solder the rib to the barrels |

I need to shorten a Stoeger coachgun 12G SxS (form1 approved). I'm pretty sure I would butcher it with hand tools. I do have a miter saw -- is that a good option, and if so, what kind of blade would be needed for a clean cut? Cleaning up the cut end is what takes time. A very fine hacksaw blade takes longer but makes the clean up go faster. A milling machine is handy for faster clean up. |
