· Old timer
I didn't think Clay's had a listing anywhere for 9mm... I use 4.0 grains for 230g .45 ACP.
I shoot my .45 reloads out of my 21SF all the time. Thousands and thousands of rounds, no blown cases. Two squibs (my bad), but no blown cases.Probably true. I reload for rifles/revolvers but shoot nothing other that factory in my Glocks. I've heard of others having issues so I just avoided it altogether. Plus, my Glocks are used for carry and I don't wish for any legal issue over carry ammo.
Except 9mm, per SAAMI specs, can produce nearly twice the pressure of standard .45 ACP... but hey, it's all the same, right?I've shot thousands of rounds of 45acp using range brass loaded and loaded again. There is nothing wrong with range brass. A visual inspection prior to loading is all I do. I surmise 9mm isn't much different. It's not like its rifle cases which should get a specific number of reloading because each firing requires trimming the neck.
Would you ignore range brass as a possibility if you were blowing cases?I own nine Glocks. Except for my SD ammo I don't think seven have ever had factory ammo put through them. I also load brass I find all the time. I'm not pushing the limits with my reloads though. Only guns I have loaded hot for are 10mm.
Good information in the replies. I would double check everything. Also running some factory ammo through is a good idea.
If they're the same headstamp, you're probably right. No mention of that in the OP. In fact, the OP suggested the opposite - that it was a pile of mismatched brass. And if then proceed to have blown cases....When you find a pile of brass by the 50's or 100's with same headstamp, one could surmise its once fired factory ammo, GTG for rotation into reloading.
I do the same. The range rat who sweeps my brass is getting recycle fodder.Being a reloader sometimes I leave my brass when I know that batch as been reloaded a dozen times, is beat up, primer pocket is sloppy loose, etc, etc. Then I see somebody picks up my trash brass and figures the old timer is not keeping it.
I wondered the same.I shoot my brass until it splits or has some other visible defect. So far no problems. I wonder whether the OP is getting blown cases because he's 2/10s of a grain light on his load. Couple that with a cold day shooting Clays and you could have a problem.
From the link:There's your problem. Lee does not make a bulge buster for 9mm. 9mm is a tapered round; bulge busters are for straight walled rounds.
** Will only work with the following cases: 380 ACP, 10mm, 40 S&W, 41 AE (Use 40 S&W Factory Crimp Die), 45 ACP, 45 GAP, and 45 Win Mag.
Glock Cases: We do not recommend "fixing" cases fired in pistols with unsupported chambers, because there is no way to make them safe once they have bulged. The case wall is thinned where it bulges, and resizing the outside of the case back down to the correct diameter does not restore the case back to its original thickness. If this case is fired in a pistol with an unsupported chamber again, and this thinned section of brass happens to line up with the unsupported part of the chamber, there is a high probability that the case will rupture.
I've been reloading for over 10 years, and until this thread, had never heard of a "bulge buster". Granted, I only load four calibers, and quit reloading 9mm after maybe 1,000 rounds; too inexpensive in factory loadings.Again, the bulge buster is for straight walled calibers and specifically to address case swelling from Glock's generous chambers in their straight walled calibers (380, 40, 10mm, 45 Auto).
Glocks 9mm chambers are on the tight side compared to many other manufacturers guns. Anyone pointing to Glocks "unsupported chambers" in their 9mm guns should be ignored as they are a storehouse of bad information.
That's good to know. Two of the four calibers I load are .40 and 10 mm. I load them light as possible (more fun to shoot hundreds of them). I shoot both exclusively out of Glocks.In general, the bulge buster (and Redding's G-Rx) can serve a valid purpose for reloaders shooting mainly 40S&W (I have found my Redding G-RX very helpful with hot loaded 10mm shot from my OEM barreled G20/G29), it returns the bulged case down by the head where a sizing die die doesn't reach back to starting SAAMI spec.
It really only matters if you are reloading cases shot from a Glock and want those cases to chamber after reloading in a tighter non-Glock chamber. Glock fired cases from say a G22 will reload and chamber fine in any other Glock 40S&W chamber without any bulge buster required.
Again, only the straight walled caliber chambers in Glocks are looser for feed reliability. The 9mm case being tapered, doesn't need any help with feed.
That can't be answered directly... first, determine if it is the gun or the reloads. Try some factory ammo through it.I will gladly admit it may be my fault. I just wonder why this gun is the ONLY gun I have with this problem? My Gen2 G19, Gen3 G19 and my Gen3 G34 all have more rounds through them than this G17 yet, only the G17 has had not one, but three case failures..
