Question about fixing the "Glock Bulge"

Hi guys. I reload .40 on my Dillon Square Deal B and had a question. I check all my reloads with a Dillon case gauge and the ones that have the "bulge" I run through a Lee single stage carbide resizing die. The bulge is gone and it fits in the case gauge perfectly. My question is, is this a bad thing to do with a reloaded cartridge? I haven't had any issues yet...but I wanted to check with people who know a lot more about reloading than I do!

Thanks

I think you would be better off with a de-bulger die.

That is a Horrible thing to do with a loaded cartridge. Unless it's a FCD. But a regular sizing die will ruin the bullet and neck tension.

Since you are using the square deal you are stuck with a kit like the bulge buster. Push the fired brass through the bulge buster first and then put it on the press, size, flare and load the cartridge. Don't run live ammo through the bulge buster.

That is the bullet sizing kit for sizing cast bullets. You want the bulge buster kit which uses the Lee Factory Crimp Die.

That is a bullet sizing kit. Has nothing to do with case sizing.

FS Reloading shows the FCD in stock. The link to the bulge buster kit on their site is broken so I do not know if they have it. May try giving them a call. Right now reloading equipment is out of stock a lot of places, especially popular calibers.

I’ve used something similar to what you are doing to size the body of 357 Sig brass, using the ram mounted push punch from a cast bullet sizing kit to push the brass through a 40 S&W FCD.

Didn’t use the Bulge Buster kit and it worked fine, just make sure you align the brass in the die before pushing it through, then pick the piece of brass from the top of the die as they stack up when coming through the die.

P.S. make sure you remove the adjusting screw and internals before using.

wasn't this only a problem in older .40 glocks?

I only have one Glock so I don't know anything about a Glock bulge. In fact, I wonder if one even exists. And if it does exist, why?

It would seem to me that a properly adjusted sizing die will force the brass to the proper minimum size throughout the length of the shell. The problem being 'properly adjusted'.

Too many times, people aren't getting the sizing die down far enough. The press needs to 'cam over' to remove all slack in the system and guarantee that the sizing die hits the shell plate (or shell holder on other presses).

If the sizing die is correct and it has fully contacted the brass all the way to the bottom, why would there be a bulge? Is the die defective?

I do understand about the Glock .40 'Smiley' problem but that isn't a bulge and, in any event, it's old news.

I'm just perplexed that a properly adjusted sizing die fully contacting the brass throughout its length is somehow able to leave a bulge.

I would certainly be using a case gauge to analyze this problem.

Pretty much. The newer barrels made within the last 10+ years or so are better.

I think people refer to the "bulge" as the "smiley" as one in the same most often. You have a hard time getting a completely supported chamber on any pistol due to the cutout on the feed ramp. Some of the best case support I have seen was on 1911s modified for for shooting .38 super major pf loads.

It's on a G27 that I bought new in '99. If I got a new barrel, you think it would take care of the problem?

I am not sure of the exact time Glock made the switch to the better supported barrel. I think it was somewhere around 2000. Don't know for sure. The newer barrel will work the brass less but it is up to you. I bought my G27 barrel brand new in the classifieds for $100.

You can see the difference.

My 2009 40s&w Glock is better than my older ones but it still guppies the case.

.40 is a high pressure round with a relatively thin case, and gets expanded more than most other calibers even if there's not an obvious bulge. Most of my reloads chamber just fine without the bulge buster, but ejecting a live round can be difficult. I run all of my .40 brass through that die.

Sell the SDB while prices are high and get the 550 with a Lee sizing die.

What dies are you using to resize/deprime?
I use Lee and have never had a problem with the die not removing the slight bulge.
Not good to use a resizing die on a loaded cartridge in my opinion.
Are you shooting the rounds in a/the same Glock?
If so use the chamber as a gage for reloading.
Just my nickels worth.

With the SDB he is stuck with proprietary SDB dies. His only hope is to get Dillon to send him a Small Base die. This is why most of us try and talk people out of a SDB and into a 550.
