    Are used barrels worth buying? From time to time I see used barrels on eBay or other places like. I am planning a 6.5 project and I found a used pac-nor barrel. It is chambered in 6.5-284 and I would re-chamber to something bigger. The ad says it has 1100 to 1200 rounds down the tube, but since I am thinking of something bigger the new chamber should take care of the old chamber and throat. If I can get it cheap enough, would it be worth the gamble?

    In my opinon, for what thats worth, I woulnt put the money it takes to rechamber and thread the bbl, it may not shoot or if it does just how long will it last. Start with new, that way you know what your getting.

    Yes, they are. Providing you're willing to accept it a couple inches shorter than the original and there's enough reinforce left to safely contain the pressure.

    Just be sure at least an inch and a half of the rifling at the back end is removed by the chambering reamer. And the 'smith uses a reamer with a free-turning pilot no more than .0002-inch smaller than the eroded bore diameter.

    I'd say some used barrels are worth buying, but I'd stay away from that one. 1100-1200 rounds through a 6.5-284 is quite a few and while you could re-cut the chamber and throat larger you may only get an additional 5-600 rounds and if you're going larger than a 6.5-284 you'll most likely not get that many.

    I've bought several used BR barrels for varmint rigs mostly 22 and 6mm cals , geberaly they have the threads cut off and rethreaded and that uses up about 2" then the calibers are generaly a little longer than the BR ones that helps take up another say 1/2"-1" I have never had one that woulden't shoot great yet.
    I started doing this when I first started playing with the rilfe building thing , (I had a great boss that let me use their lathe) and it seemd like a cost effective way to learn. My theory was that if I got a 6mmBR that was used for 200yd BR matches and it had gone south that meens that it may have started grouping as big as 1/4-1/2" and that is still way under what I was expecting to get so I figured what the hell.
    But like I said , I was simply using them to learn and wasen't expecting the world to start with.
    If I were goin to pay for the machine work I'd buy a new barrel

    I would not replace my barrel if it is a shooter. If it wont shoot I will replace it and may put it on eBay. I think I would stay away from them.

    Personally I would buy a used tube from a known source (IE close bud), but not from the rest of the world.

    Mark has a good point. Buying a used barrel from an unknown source is like buying a pig in a poke...or whatever they say.

    The seller may claim to have fired 1,200 rounds but there isn't really any way for you to know. Besides, total round count only tells part of the story when it comes to barrel wear. How hot the tube was shot and how well it was maintained can also be significant factors.

    I once sold a Shilen Select Match barrel to a guy on the internet. I keep accurate records of everything I load and knew that the barrel saw just under 1,000 rounds. However, I also knew that he didn't know if I was telling the truth. He asked if he could have 2 days to borescope the barrel with the option to return it for a refund. I had no problem with that and the barrel was shipped.

    I guess he was happy because I never heard from him again.

    Just my 2 cents on buying used barrels.
