Would you reload this bulged 10mm brass?

    Since I've had a recent 10mm failure, which may not have been at all related to bulged cases (I'll post that update separately), I have been culling bulged brass. Attached is a picture of brass that I would toss, and I am wondering if I am being overly cautious and what you guys would do with these examples. These cases have been run through the Lee Bulge Buster.

    They each “plunk” just fine in a gauge.

    Thanks

    If they fit the gauge & plunk the barrel, load some and see how they feed, cycle, shoot etc.

    You can remove a wicked bulge with the bulge buster. My question is what were the cases like before you processed them. The severly bulged (guppy belly) brass is the stuff I will not reload as the brass has been stretched in the area of the web and possibly compromised by it.mark any with a marker on the head and inspect well after shooting them and see, if you do use them that is.

    I would shoot them in a gun that doesn't bulge brass.
    For me I pick up lots of bulged 45acp shot in glock or glock clone, then reload them to +P shoot them in a 1911, reload them over and over until the head stamp is gone or they won't fit on a shell holder any more.

    My reloading motto on questionable brass is "when in doubt, toss it out". My hands and eyes are worth more to me than a few pieces of questionable brass.

    Yes I’d resize thru a bulge buster and reload. I have a G20 with a KKM barrel and a HiPoint 10MM rifle in a Bullpup stock that I’d shoot them thru.

    What are you reloading them to shoot in? If it’s a Glock is it a factory or aftermarket barrel?

    Lennyjoe asks some good questions.

    I'd take my Dremel to a couple of them. One before sizing and another after sizing. It's not very scientific but it does expose the web and I think it's fun.

    And after all that’s what we’re here for otherwise it’d be called work, not forum.

    Then it's too late to learn much by looking at them.

    Look before bandaiding the damage.

    Considering that you've demonstrated the high cost of a failed case, and I don't know of a way to detect incipient failure just before it's going to occur, I would ere on the side of scraping any visibly bulged brass.

    Just a minor bulge (Gluck smile)? Yes, I would use.
    A significant bulge (like FROGO207 called guppy belly)? No.
    A cross section as suggested by mokin is a good idea.

    Wrong question to ask.

    The bulge is telling you that something is wrong.
    So the question is... Why are you still shooting loads that bulge the brass ?

    Forgive my ignorance, I do not load 10mm or really hot .45 ACP or 9mm, but it almost appears to me that this brass has a bulge from resizing where the case is not sized where the cartridge case holder and the sizing die meet. The “bulge” appears uniform. I am not familiar with the Lee Bulge Buster Die.

    I culled this brass...meaning I separated it for disposal, not to shoot again. I was simply asking if I was being overly cautious. This brass doesn’t have a guppy belly, but I can still see a slight bulge. Here’s a picture before running through the sizing or bulge buster.

    Doesn’t look abnormal after being sized. The die doesn’t size the brass all the way down the case. The die stops when it hits the shell holder and there will be a small area unsized. Looks like that’s what your calling a bulge.

    This case is definitely bulged with a Glock smile so I wouldn’t reuse this case in any way.

    Agree. Though not as noticeable, the brass I show is indeed slightly bulged from my unsupported barrel. With a higher charge, I’ll get brass that look like what you showed. Here are some loaded rounds, also culled as I'm not comfortable with their appearance, although they plunk just fine in a gauge.

    My fully sized brass measure .4130 thru the center to .4180 just at the bottom section. But the .4180 is uniform with no variation around the case.

    It's been said many times, but here goes again; The brass is stretched where the bulge is, you run it thru a Bulge Buster to make it fit back in the chamber, BUT, it does nothing about the fact the metal was overstressed in that spot. Reload it, shoot it again, and the previously bulged spot loads in a supported position - the shooter thinks they solved a problem. They didn't. They just got lucky. Repeat until the bulge happens to load in the exact same, unsupported position and get a Kaboom!. Then spent lots of time and effort trying to "figure out" what happened.
    Lather, rinse, repeat endlessly
    IMHO Bulge Busters are 2-purpose tools;1) Make the case fit back into the chamber, 2) Give the reloader a false sense of security. The 'plunk test' only reinforces the trick. It tells you absolutely nothing about the condition of the case except it will fit.
    Ask yourself this question; If you had some bottleneck cases with the prominent ring around the head indicating an imminent head separation, would you run it thru a 'bottleneck bulge buster' (if there was such a thing) and shoot it? ? ?

    Exactly. I am sure many of us have taken a thin piece of metal (any kind) and bent it back and forth and if by "magic" it then breaks in half,

    In the end the decision is up to you. Resize and shoot or buy new.

    Throw them all out!!! Better yet, I’ll recycle them for you. Put in a flat rate and mail it to Seattle!

    As stated above the risk is using them in an unsupported chamber multiple times. That is when it is not worth it. Using range brass with mild bulging that will be utilized in a fully supported chamber you will probably get away with it at least for a while. Your brass your choice!

    I see nothing wrong with these. I'd load and bulge bust if needed.

    Not comfortable? Cull as you've done and move on. PM if you're selling them.
