40 S&W brass shaving problem

[Old Gun]

I need a little advice here. I am having a problem with shaving the side of the case. See attached picture.
This is my first time reloading 40 S&W. I have a new set of Lyman carbide dies and a new Hornady shell holder. I have reloaded 9mm, 45acp, 7 mauser and 30-06 for years with no problems. This problem is happening on all of my shell, not just a couple.

Is this the die, the shell holder or the case?

A couple notes that may help.

1) If I turn the shell holder to different position in the press ram it seems to be better or worse.

2) I have tried case lube with the carbide dies but still have the saving.

3) If I only size about half way down the shell I don't have shaving but see a bulge in the side of the case below where it has sized.

4) If I only size about half way down the shell then back off and rotate the shell in the shell holder 90 degree or 180 degrees then size the rest of the way the bulge is smoothed out and the shaving does not happen most of the time.

I am suspecting that the shell holder has a problem and is not holding the casing exactly straight up.
Any ideas?

Your die is probably scratched on the inside

What picture?

The picture didn't make it through the tubes.

What gun did the brass come out of? Glocks are known for bulges and smilies.

looks like he is shooting them out of a glock. you need to get a bulge buster die. Glocks make the brass bulge out. It can also be from the brass getting old.

40 S&W brass shaving problem

I think I have the photos attached now.

The brass came from various sources. I none of which are my Beretta 90-two which I am still waiting to get out of 10 day lockup.

They look very much like the problem of the Glock. Does someone have an idea how bad this smile (ledge) can be before it causes a loading problem? I tossed a dozen or so case in the trash as they looked bad like the one in the photos.

[Solus]

I would toss any that are scraped. you dont need a blow out. in your gun. I suggest getting the lee bulge buster. Its in the link I sent earlier

Your die is shaving the case because you are trying to size too much at once. Some Glock fired brass are expanded beyond what a standard die can handle. You are going to have to get a Redding GRX die or the less expensive Lee bulge buster. These will size the brass to get you to the same level as if it were fired in a tight-chambered semi-auto and then your standard sizing die will be able to do the rest.

Or you can try your luck with another sizing die. I want you to know my RCBS sizer does the same thing to Glock-fired brass.

What model, gen, year is your glock?

Check the shell holder really good for any burs that might be throwing off the alignment. Make sure the shell holder is not loose or flexing on the press.

[JagerDog]

I'd ask what type of press? I've seen c-frame presses "stretched' so that they were no longer axial. I've seen steel dies "polished" in the direction of stretch so that they worked, but problems with new dies.

[J-cat]

My press is an "O" press and is doing the same thing.

My shell holders are perfectly aligned.

This is an over-expanded case issue.

[mindwreck]

listen to this man.. check your carbide ring. probably cracked.

Your die is probably scratched on the inside

Any ideas?

Cases do not expand uniformly. They expand more on one side than the other. This is due to their orientation in the chamber. The case is pressed against the left side chamber wall by the extractor. This leaves more room on the rights side of the chamber, so the brass expands more in that direction.

When you are resizing the case, the side with the greatest amount of expandion will get worked more, hence the shaving.

This is not an alignment issue.

That is pretty deep shaving. I've had a bit less on 30 carb ... after a good ultrasonic cleaning it stopped.

On my glocked 40 brass. The regular die just leaves a little bit of bulge above the rim which the buster die pushes right back in.
