The Glock Bulge

[jrplourde]

I apologize for jumping thread here (probably get my wrists slapped). I am referring to the very recent thread on the subject (Glocked 45 acp --a very good read) but wish not to be on page 39. I need some of that valuable forum thoughts now. Will be loading for local PD soon and they are using Glocks.

Whether the Glock bulge is from high pressure or thin brass or whether the bulge is removed with an RCBS or LFC die or whatever, is the brass being uniformly redistributed/replaced or for that matter, is the bulge uniform in thickness. I doubt it. Therefore, there must be a thin spot in that area and if that spot subsequently finds itself over the same unsupported chamber area , is there a more serious issue pending here than simply satisfying a case gauge?

Is this for practice or duty?

My original thought was, "There's a PD in NH that uses handloaded ammunition, reloaded using once (or more) fired brass, in their Glock's?"

Practice use. Need a bunch and can't get any.

Good for you! I'm glad you can help them out.

When I had a G20, I used my reloads in it all the time with no problems. That brass got mixed in with the stuff fired out of 1076 and was reloaded and used in either or both with no problems. I have friends that shoot my .40S&W and 9mm reloads out of their Glock's with no problems. That brass gets mixed together and reused, just like the 10mm.

I don't load my target rounds to max pressure so that may be part of it but since it's for practice and not life or death, it may not be a big deal if a piece of brass is unusable after numerous reloads. Although it may be embarrassing if they get malfunctions.

The Gllock Bulge

Hi:
I thought that Glock discourged using reloads in Their Weapons?
Several years ago My Agency was notified by Glock that Glock would not warrenty Their Weapons for reloads.

People think too much. Glocked brass will last just fine, just discard the cases that you would normally discard with any other gun

Glocked Brass??

If you are going to reload .40 S&W brass fired out of Glocks then you may well have the bulge. The .40 round is fairly high-pressure and is notorious for the Glock bulge. There is now a simple push-through die made to take the bulge out before you reload the case. Please be sure and use only jacketed bullets for your reloads. Lead can build up in Glock barrels and cause Kabooms!

The 45acp brass get lost, and swapped for other's range brass so I try to shoot it until it splits. It is low pressure and loaded for target shooting. I really don't have a way to measure thickness, I just handle it alot and keep an eye out for split cases. I did recently measure overall case length, and it seems a very small amount shorter. The undersized die is shaving a little brass, and should probably have the cases lubed. But I don't want the mess.

Indeed. As with any such pistol cartridge, a carbide sizing die and a Lee FCD in the last station will do wonders to remove the bulges and greatly reduce FTF's.

I shot 170 gr hardcast SWC's in my Glock, with its factory barrel, all the time I had it.

That said, I wasn't an idiot about it. Glocks come with a bore brush - USE IT. I did; after each match. I also put a couple of jacketed rounds at the bottom of the last mags in a match to reduce foulings. No Ka-Booms.

They told us that too. My department uses G23's and G22's so I bring home Glock fired .40 S&W brass by the buckets full. I've loaded thousands of rounds on my Dillon 550B using Dillon dies and never had a problem (always using jacketed bullets, of course).

As long as you are not trying to make major with your powder charge, you'll be just fine.

Even my S&W 1911 says no reloads in the owners manual. That is the lawyers heading off lawsuits. Competition shooters all reload, over and over til the brass fails. If it's a .40 fix the bulged brass with a Lee or Redding Grx die, and you're good to go.

Redding now makes a push through resizing die that will take out the Glock Bulge. The Lee Carbide Factory Crimp die will also remove the bulge on most cases.

EGW makes a die that will solve that problem. ( evolution gun works) It sells for about $25. It is called a u die (undersized)
