After band sawing it should be faced off on a lathe or side milled on the milling machine and de burned. A hack saw will always take longer because you are using Armstrong feed. I highly recommend the tubing cutter as long as there isn't a vent rib on the bbl. |

Every time I've used a tubing cutter on anything a giant burr is left behind. |

Every time I've used a tubing cutter on anything a giant burr is left behind. This. Also the rollers / contact area will leave marks in any finish on the barrel. My gun is 23" OAL folded. Such a difference lopping off the extra barrel. My gun is brand new otherwise I would remove the barrel, thread and put back in. Checked my barrel for concentricity and it's perfect so will use a piloted button die to thread after it's faced off in the mill and chamfered. |

I cut a long ass pump shotgun down to 18.5 for a small cousin who has a small farm that backs up to state forest with critters that tend to get too close to her ducks , chickens and dogs. black bears also creeping around. Anyway , she has not needed to shoot anything but wanted a tool to keep on hand. I had lots of extra barrel to work with so I tried some different stuff. Hacksaw-hard to keep straight sawzall not to bad but not perfectly straight. Tubing cutter- left big burr inside barrel and rollers marked up the outside of barrel. Chop saw with metal cutting fiber disk blade. had to go pretty slow as too much pressure caused lots of heat which marked up the blue finish. going slow with breaks to let things cool off was pretty good. Cleaned up burrs with hand file and different grits of wet/dry paper with a sanding block to keep it square with the end and a bit of cold blue touch up . Gun was a old High Standard that was a bit worn that came off the used rack at the local gun store that I believe I paid $139 for. Picked this gun as it was pretty chunky with a steel receiver and I wanted the weight so recoil wouldn't beat her up as she is small (100lbs maybe?) |

I'm all in on the box mag fed semi auto shotguns. They're getting better all the time. |

Every time I've used a tubing cutter on anything a giant burr is left behind. A bandsaw will cut faster than the tubing cutter, but I might have had a nice new sharp tubing cutter, and didn't get much of a bur. But deburring isn't hard. Either way will work. I don't have a mill or bandsaw at home, just at work. And that wouldn't end well if security saw me coming in with firearm parts into the secure area. |
