Glock fired brass

I discovered on Lee's web page that they recommend that you do not reload brass fired from a Glock because it has a unsupported chamber. That brings a question to my feeble mind. How does one know that their once fired brass didn't come from a Glock? This applys to purchased brass and "pickups" at the range. Comments please.

    Very good point if in fact this is true .

    I just load em until they split or until I can't find em .

    Looking forward to what the other folk's have to say on this one .

    I have shot Glocks in 9mm, 40 S&W & 45acp for years. I reload the cases just like all the others and have never had any issues. I will state that I have not loaded the 40 S&W nearly as many times as the 9mm & 45 but some cases at least 3-4 times. Might be an issue will really hot loads.

    On many range pick up if you look closely there will be a BELLY bludge just in front of the extractor groove and a line where the transition between feed ramp and chamber is. You will also notice that the reloading press will be much harder to work to size the case. I personally think that this information is Valid. But then again I am not fond of Glocks after seeing a number of KABOOMS with factory and reloads. FYI most but not al of these Kabooms are with the 40.

    I have loaded a lot of Glocked 9mm brass and some .45 with no problem. I do not own or shoot .40 which is where most of the alarms come from.

    You can recognize a case fired in any Glock by the rectangular firing pin hole mark on the primer.

    The local police chief supplies me with 40 cal brass all shot from glocks. I have not had a problem other than an odd one that won't chamber because the sizer didn't catch the "bulge". I suspect that is as much the issue than anything else. I noticed somebody makes a push through sizer die specifically for this problem.

    Yeah, very easy to tell the difference between a Glock fired case and anything thing else. I have about 500 pieces of Glock brass that I picked up after the shooter was done, no problems with it. I am sure some other cases I have are Glock fired.

    The problem is with 40 brass. As stated some sizing dies won't go down far enough to take the bulge out.
    You can tell Glock fired brass by looking at the primer. Glocks leave a long firing pin mark instead of a round one.

    I have reloaded 1000's of cases fired thru my G22, never an issue. I run middle of the road loads with 40S&W. My pet bullets are either a Berry's or Rainier 165gr plated FP...again, never a problem...my 2 cents

    I reload a lot of range brass in 9mm and find quite a few that either won't comletely enter the sizing die or require way too much effort. Sometimes, there will be a beltlike ridge ahead of the extractor groove. I saw an ad for a die that smooths out the 40 S&W brass prior to full length sizing for cases like these.

    I have a friend who is a commercial reloader. He will not accept Glock fired brass for reloading due to the stretch near the web caused by the unsupported chamber. He states that brass is not a strong metal. Even if you resize a pistol case so the bulge is gone, the brass is weakened where the bulge occurred. Consequently, the probability of a ruptured case (and a ka-boom) is significantly higher. The problem is more likely to occur in a .40 S&W since it is a higher pressure round than other pistol cartridges but the case rupture can occur in any caliber.

    well my boy... a glcok has the only firing pin in the world that is "self cleaning". meaning a normal fring pin is a single point pin, which can cause it to stick into a soft primer,break easyier and mess up your day and cause the gun to jam. A glock firing pin looks like three fingers in one, the middle finger being longer than the other two, that way the outer two "finger" shove the case off the pin, so it will never jam becasue of a soft primer, or soft strike.. and if you look at the bottom of the case you will see a longer primer strike than your other guns, so the short if you see only a small strike on the primer it was not made from a glcok... a glock will have a longer, almost three strike on the primer.

    Hello Fathead I guess I have just been lucky that my 1911 Match gun has over 300,000 rounds through it and never punched through a primer never broke a firing pin and never jammed and spoiled my day because John Browning did not know how to design a firing pin. [;)]

    The Glock bulge as it is called is due to the fact that Glocks have a loose chamber, not a unsuported chamber to increase reliability in feeding almost anything. The problem in reloading Glock brass is that some dies will not go all the way to the bottom of the case due to the starting taper on the die. You can grind your die down about .060 and eliminate this problem in resizing. The reason for not reloading Glock brass is that you keep bulging the same place on the case causing metal fatigue and after a couple reloads you have a grenade with the pin out if you are loading hot loads. Personally I reload Glock brass for my XD and have had no problems other than a tight case that won't fully chamber some times. Once fired Glock brass is fine if your putting it in something else to reload and shoot. Do your own research and load at your own risk.
