Ridge from sizing "Glocked" brass

I do minimal .40 reloading, but anything with a bulge goes in the recycle bucket. It is plentiful where I shoot, but much of it is from competition shooters who reload it. Those cases(bulged) are more stressed than others, and while you may get away with it, you may not. I would say don't risk it and discard it. This coming from someone who once scrounged and tried to salvage every piece of brass possible. I learned the hard way to discard anything even remotely suspect. I have never damaged a gun or hurt myself, but I have had a few surprises with range brass.

Those look like they were not being sized on center the reason for the offset scrape. I would not use those.

Those are done.

Please crimp them at the mouth and recycle them.



Lee makes a "bulge buster" for glocked brass, but then advises not to use bulged brass from glocks resized in this fashion- very lawlerly.

I size all 40 brass through it once before I use it, and some 1200 plus pieces through it, and normal dies, I have yet to see anything like what you have there.

Looks kinda like the sizing die didn't go down quite far enough.

Toss it! That's from being resized over, and over. That's area gets thin, and will soon separate. You will notice a line in that area on once fired Glock brass, but it won't be that defined. As the brass is loaded over, and over, the brass flows to the mouth area leaving that area thin, and the ring becomes defined.

It's scrap.

Nope, that brass has expired.

I would also inspect and clean the shell holder, as that can cause brass to be off center when resizing it. But not knowing if the defect runs the entire circumference of the case makes it difficult to know for certain if it's G bulge, if it was off center when resized, or just expired brass. Either way, it's recycle brass now.

As others have stated, discard that brass. The thinned web makes it unsafe and unsitable for further use.

Who's the make on that brass, BTW? I've only ever had this issue with S&B brass fired from a Glock chamber. It sizes poorly like that after one firing, and even factory loads wouldn't reliable feed/cycle in my tighter chambers to begin with.

A re-occurring with Glock factory chambering. Lee makes a glock-buldge die which re-sizes these bulged cases for another reloading. I have my doubts about shooting any of them in a original Glock barrel. I have replaced my Glock barrels with Wolf barrels and don;t have this problem any more. Working the brass cases in this area can't be good!

What about these? They have the small ridge after resizing with a lee die. They are no where near as pronounced as the op's. Are these safe this what all my brass looks like after resizing no matter whether it was a fired out of Glock or not!

Those look good. See no problem in them.

Yes SouthernDawg those look fine. That fine ring you see now will look like the OP's pic after a while if you don't loose them first. I inspect all my .40, and 9mm brass after cleaning for the ring like you see in the OP's pic, and splits. It's not worth loosing a firearm, or worse a hand/eye to poor QC.

Redding also makes a special die for .40 S&W to resize brass all the way to the case head. This is a push through die for cases fired in "unsupported chambers". To my knowledge, it is available only for .40 S & W. However, anything that is bulged as much as shown is a wrecked pistol & possible injury waiting to happen! I should stop here, but, will state that this is the reason I don't own a .40 S & W. The pressure curve spikes too soon. I have friends who experience the same issue with all brands of this caliber. However, the primary offender seems to be the early Glock 22 models.

Take Care!

This brass was R-P but had the same issue in the last few days with WIN, Winchester, federal, perfecta, blazer and Speer brass.

If you are getting the same ridge from all different headstamp cases, then the problem is not specific to a headstamp and I would look at the resizing die and die to shell plate alignment.

I use RCBS and Lee carbide dies for 40S&W and both have nice round radius on the carbide sizer ring mouths and do not cause sharp ridge that show on the pictures. BTW, Lee carbide sizer ring resizes the case further down towards the base and to smaller OD to the point I do not need to use undersized "U" dies or "push through" resize with the FCD. Regular Lee carbide sizing die is my preferred die of choice for 40S&W for these reasons which seem to help produce greater neck tension (FYI, some Dillon match shooters specifically use 40S&W Lee sizing die). When reloaders complain about tight chambers of Lone Wolf 40S&W barrels, I tell them to use Lee sizing die.

They look just like resized brass from my Lee dies.
