Reloading Glock brass okay?

    I have been reading about cases bulging after being shot in Glocks. Is Glock-fired .40 okay to reload? Any problems or issues that need be addressed? Thanks.

    I don't generally reload brass fired in Glock handguns. Glock has an overly large chamber to enhance feeding and the case is not fully supported where the chamber is inletted for the ramp. This causes a bulge at the 6 o'clock position of the brass as it sits in the chamber, which weakens the brass in this area.

    In particular, the .40 S&W is a fairly high pressure round. It's not as high pressure as the 10mm or 357 SIG, but still up there where you want as much safety margin as possible in your brass.

    There is plenty of .40 brass available, so there is no need to reload brass that may have been stretched too far.

    Hope this helps.

    I usually get 6-7 loadings out of brass fired by my G22 with no problems. I'd get more loadings out of them if I could recover more of my brass. According to my reloading books my pressures are between 26,000 to 33,000 PSI and never had a split case or any other signs of failure.

    I've been realoading Brass from Model 30 for years now. No problems.

    I reload it several times and then throw it out. Just for giggles I have loaded Winchester, Remington, Federal and CBC cases 12 times each at top end power levels with no failures or problems.

    If the load makes a blister on the case then by all means throw it out, if it is just out of round by a couple thousandths near the base as 99% of autoloader brass is then reload it.

    I reload cartridges out of my my g23 with no problems. However, if you have reservations and don't feel it is safe, you can always send your old brass to one of us. I am sure there are an abundance of people on this board who would pay shipping to take it off of your hands!

    Actually, if you see some of the brass that I've reloaded over the years, you'd be surprised that I posted the question. However, I've never loaded for .40 (although I'm sure a lot of the 9mm stuff I've reloaded has been shot through Glocks), and I've seen several posts regarding Glocks blowing up and how the brass bulges. I was curious, and appreciate everyone's replies. Thanks.

    There is no reason to load any brass that you may have doubts about, whether real or imagined. I've seen a lot of factory new .40 brass come out of Glocks with a rather pronounced swell at the base. I get most of the brass from our Rod & Gun Club, and almost all the police fired brass. They only shoot factory ammunition through their guns, and I see swelling in some of it.

    The last time I went to the metals recycler, I took over 5,000 rounds of once fired .40 S&W brass. I tried to sell it and then tried to give it away, but no one wanted it, so it went for recycling at $.42 a pound.

    Life is too short to load bad brass. I cull a LOT of brass some people might consider just fine. I just don't want to take any chances, if I can help it.

    I reload Starline cases out of my G20 10mm. Some are cranked up pretty good, but I use Blue Dot which is a "slow" powder (in the pistol world). I guess mine has a stock barrel (bought it very slightly used) and I've never been able to find the bulge.

    This is an absolute wild guess, but I suspect the cases that bulge the most have max loads of faster (and therefore cheaper) powder.

    I have wondered about this. I got some once-fired brass, and sure enough some of it has some pretty good bulges on one side, in the lower half.

    Well guess what, it still sizes perfectly. I am currently planning a test to mark the side where it was to see if the same area expands after other uses. Maybe I will let you know, or you could try that test. I dont use a Glock.

    Strangely, a bigger concern for me is the lack of neck tension after they are sized & flared. Some of them wont even hold the weight of my press handle, so they are gone.

    I don't load .40, but do load a lot of .45ACP. I have no problems reloading brass that's been run through my G21 or G30 in my 1911s.

    Just examine all your brass before you reload it. Glock brass is fine. As others have mentioned, if you have severe reservations about it, please just sent it to one of us.... ;)

    Little explaination....

    I think people tend to paint things with a broad brush

    my Glock, or rather one of my friends Glocks, or rather one of my friends heard of a guy that had a "_______" problem with a Glock

    now, I'm not gonna say it doesn't happen, but I crank 180's downrange at 1,300+. My brass doesn't bulge out of my G20.

    Maybe some .40's do. My 10mm doesn't, and it'll kick the crap out of a .40. Take it for what it's worth. This is my gun with my load.

    I know there are guys here that have a LOT more experience than me. I also know there are some armchair coyboys that spout garbage and have no idea.

    I'm not particularly a Glock fan, but I think there's more unfounded rumors than truth. YMMV.

    Reloading Glock brass isn't any different from any other brass you reload.

    Toss out ANY brass that looks even slightly suspect upon inspection.

    Obviously, if any looks pregnant, give it a toss.

    From what I read into many of the KB's, they were predominantly traced back to either Federal ammo (possibly bad batches), shooting lead out of a polygynal barrel or pushing the limits of a 40 S&W reload. Many of these *may* have been double charged, others not.

    I have reloaded quite a bit of brass fired in Glocks. It's easy to spot because the firing pin indent is unique. Like any other reloads, I don't push a load near, or to max levels without knowing the history of the brass first hand. I will load my own, known once fired brass a little hotter if necessary, or I will use new brass from Starline.

    I have rarely found it necessary to load a particular round to max levels. Often, best accuracy is found with charges more in the mid and upper mid range of published data.

    I load hunting rounds to the best accuracy, if accuracy doesn't suffer, I will load them hotter - up to max levels if no over-pressure signs occur.

    If you don't feel comfortable reloading the brass, give it to someone who will. If your caveat is regarding *firing* reloads in a Glock due to unsupported case head, either buy an aftermarket barrel that offers better chamber support, or shoot reloads in another weapon.

    Many reloaders shoot the Glock factory barrel with reloads with no problems. Most of those (that I am aware of) do so with plated or jacketed bullets only. Leading in the polygynal barrel can be bad juju if not cleaned regularly and properly.

    In any event, don't trash the brass just because it has been fired from a Glock. Many pistol's utilize unsupported chamber designs. KB's occur in many pistols, not just Glocks. Glocks have certainly been more publicized, but that doesn't imply that you are immune from KB's in any pistol.

    Component failure or user error when reloading can be catastrophic in any weapon.

    Just my .02 cents... FWIW

    No problems with reloads in either my 17 (9mm) or my 22 (40 S&W).

    Big Slick;
    I have a bunch of .40S&W brass I have been using for other than reloading, about 30% have the body at the base expanded about .025.
    What is unique about the Glock firing pin strike that makes it readily identifiable?
    Thank you, Don

    Glock firing pin leaves a vertical line across the primer, as opposed to most others that leave a round indent. Glock fired brass is very identifiable by that indicator.

    Jayman describes a Glock firing pin indention perfectly.

    Look thru a few and you will see, the vertical indent vs. round used/caused from other pistols

    I load lots of 9mm cases that have been fired in glocks and have had no problem. I am not a glock fan by no means, but the brass,if it looks OK it gets cleaned and reused.

    Redneck2...Could you please explain your comment? I quote: "This is an absolute wild guess, but I suspect the cases that bulge the most have max loads of faster (and therefore cheaper) powder." I don't understand...If it's faster it's cheaper??? :D
