Ya'll wanna kick this subject around a while? For the longest I never knew about issues with reloading for Glocks.

I don't shoot reloads in Glocks...but I aint scared to either....So one of your Glock guru's out there kick this around:

Here's a little something for those that don't know what I am talking about:

'neck, this is a bogus link. Every time I click it, it shuts down internet. Check it again on your end. I'm up for some talk of exploding Glocks.

:bull: first off, this info is from 1998 when everybody was on the bandwagon against Glock due to market takeover. Glock changed there design some time back, can't remember date, to alleviate such problems. second is ALL MANUF. void warranty if shooting reloads. 3rd, Glock rifling in barrel causes over leading due to the Polygonal rifling. If one was to scrutinize other manuf. like they have Glock, you would see the same results. I'll think of some other stuff later.

Good deal....I know Glock got blamed early on and it is possible in any semi-auto.

You always seem to see Glock mentioned however.

It has sparked quite a few conversations on other gun forums...I just wanted to hear what ya'll thought.

'neck, the 2nd sight worked fine for me.
O.K. here goes.
I got started into reloading the wrong way. I bought a bunch of reloading supplies from local gun shop when thier "smith" passed away. Had a friend with a dillon and he said come on over I'll help you out. Well the bullets I had were lead 155 gr. swc. We could not find any data so we started with some data for a lighter round. Loaded a few and tested. Too much leading in the barrel.( did not know at the time about polygonal rifling) we worked down the load and became satisfied. Well we loaded about 900 rounds and called it a day. I shot these succesfully for a couple of months, then it happened! Was shooting rapid fire and KABOOM! Burning powder in the face, hand felt like a dozer rolled over it, and was scared to look. When I finally looked there were no exposed bones or blood for that matter. I was sure my hand had been shreded, but noooo! Looked at the 23 and it looked fine. Upon further inspection the mag had been pushed down and the slide was locked back. I dropped the mag and went inside to inspect the gun good. After breaking down the gun i found that I had had a total head sepparation. (rim gone, case wall still in the chamber) Well I managed to remove the stuck case and decided to check the gun further for damage at work. Now, I am a machinist by trade, so all of my precision tools were there. once my inspection measurement were done I found nothing out of spec. I called Glock and they said to have it inspected by a qualified armorrer. No $ for that so I put the gun up. After several months I decided to try it again, but with factory ammo this time! Now picture me hugging a large pine tree with a Glock in my outreached hands! Funny I'm sure. Well it worked fine, so I continued to shoot it. After inspection of the questionable loads I found a couple of them had small fractures horizontal to the base just above the rebate. Started asking around and then learned of the unsuported case issues with a Glock. I deduced that these fractures were from a combination of slight over pressure and unsupported case and slight leading in barrel. Stupid me only culled the ones with fractures! A friend went shooting with me an was firing my 23 fairly quickly and, you guessed it, KABOOM! No injuries to him or the gun( thank GOD) Well that ended the day needless to say. Long story short. I pulled everyone of the remaining rounds and salvaged the powder and the lead. The rest of the stuff is burried in a hole in in my woods.
This is just my experiance with KB's. Take it for what it is worth, but dont underestimate the KB factor and know exactly what you are doing when reloading!

Great post...real world experience.....

We are getting to what I wanted to hear from ya'll on now

The unsupported case is the "issue"...Some say a Barstow barrel will remedy it

I shoot reloads in my glocks, but only jacketed bullets. I am going to buy some custom barrels though for other reasons.

I also shoot mostly reloads in my Glocks. They are plated not jacketed though. The above thread is the only problem I have come across though. And those were lead!

Certainly not a Glock Guru; but will offer a couple experiences with Glocks and reloads. I, too, was hesitant to shoot reloads; especially, lead cast bullets through my Glocks. I have read on other gunboards of how dangerous it could be. Well, I have this problem owning several Glock pistols that will not shoot cast bullets - economy is the name of the game to me.

After a lot of reading, I learned - from more than one source - that the factory barrels used in Glocks (Polygonal rifling) were not designed to shoot cast bullets and they were prone to barrel leading and/or accumulating lead residue in the barrel. I posed this question on another forum awhile back. Here are a couple good threads on the subject -- http://castboolits.gunloads.com/showthread.php?t=33855&highlight=glock
http://castboolits.gunloads.com/showthread.php?t=33855&highlight=glock

Since there was no real consensus on the subject, and after reading many post like the one sigman offered above, I did not feel it worth it to take a chance. I ordered three Lone Wolf barrels from Dillon -- a 9mm conversion barrel for the Glock 22, a 40S&W replacement barrel for the Glock 22, and a replacement barrel for the Glock 21. Problem solved - now I can shoot cast bullets through my Glocks without worry -- SO I THOUGHT!!

Off to the reloading bench to load up some for use in the Glocks. I have loaded thousands of 9mm, 40S&W and 45acp for use in my Beretta, Smiths, Colts, and Springfield without problem. I did nothing different as I have always done!! After loading about 50 of each, I headed to the range. To my dismay about 10% of the 9mm, 5% of the 45acp, and 60% of the 40S&W would not fully chamber in the Lone Wolf barrels. The weapons would not go into full battery - a dangerous situation; especially if the weapon would fire -- I have read that the Glock will fire out-of-battery if it is close enough. I scratched my head, loaded up my stuff, and headed back home …

In working out this problem, decided to use the 40S&W since I had the most trouble with it and felt that if I could find the problem with it, the others would follow. Since I was using the exact same set of sizing dies as I have always used, I did not think that was the problem -- maybe the Lone Wolf barrel had an extremely tight chamber and the cast bullets were sized too large for the Lone Wolf barrel. The bullets were sized at .401. I slugged the bore -- no problem there. Maybe the bullet is seated too long for the Lone Wolf barrel -- loaded a few more at a shorter length and went back to the range (I consider myself lucky in that the Magnolia Rifle/Pistol range is 3 miles from my driveway). Problem solved? -- NO!! Still had the same problem and another more serious problem developed. Looking at the rounds that did fire, the primers were punctured from the blowback pressure. Want do that again!! Be careful not to short seat 40S&W bullets!!

Well, I have all these gages sitting on my reloading bench - why not use them? I took several of the rounds that would not fully chamber and placed them in my case gage -- they would not fully seat into the case gage. I could not understand what was causing this … since I have not had any problems in my Beretta and Smith 40S&W. I posed the question on several other gun boards and the answers that came back were all the same -- I HAD GLOCKED BRASS!! The factory Glock barrels are not fully supported in the chamber area - also the 40S&W is somewhat a high pressure load. When ammo is fired through a factory, unsupported Glock barrel, the brass is overly expanded at its base. Here are a couple of pictures of the situation:

Brass that fully seats into the case gage after sizing:



GLOCKED Brass - After sizing will not fully seat into the case gage:



Back to the reloading bench -- did some adjustments on my sizing die, and cranked out a few more. After the adjustment, I was able to use most all of the GLOCKED brass. However, I still run into some of the 40S&W that I can not get down to size for use in the Lone Wolf barrel. Additionally, this has added another step in my reloading process. In order to avoid FTFeed issues with aftermarket barrel, I must check each sized case with the case gage -or - barrel in order to cull those that will not fully fit. However, this seems to have cured my problem -- couple hundred rounds with no FTFire and no FTFeeds in all three calibers.

As a side note, I will add that the use of a good tamper crimp also helped ….

WOW...Best post I have seen so far...Good job...I have learned a ton here.

So one of the morals of the story is you have to be particular about using "range brass"...I get it all the time from Surplus City $3 a lb...now I'm kinda worried about it..."Glocked Brass" that is.

Very Good Post captain

makes perfect sense. if not fully supported, this expansion can happen. I suppose the new term of the day is "Glocked Brass" = brass fired from a glock handgun that can't be reloaded w/o use of a properly set sizing die and checked individually with a case gauger.
good post. capt.
