small base die for 9mm Luger?

They make a die do remove the Glock Bulge. It's called a Redding G-Rx die. It's a push through die.

Lee undersized die

Lee recommends not using Bulged brass from Glocks (but sells the kit to fix it)

I use the FCD and shoot a couple different 9mm including a Springfield 9mm "Loaded" 1911 (sweet gun)
I haven't ran into any issues with any of the range brass I have picked up as far as chambering.

Unless it was a large portion of your available brass I would be tempted to just toss/recycle it.

It's only for the 40 S&W. http://www.redding-reloading.com/online-catalog/121-g-rx-carbide-die-set

9mm is a tapered case and there is no "push-through" Bulge Buster kit for 9mm. President of Lee Precision John Lee did attempt to modify a 9mm FCD to use as "push-through" Bulge Buster a few years ago but it never made it to market. Lee carbide sizing die's carbide ring is tapered and I found Lee sizing dies (especially for 40S&W) size brass to smaller OD and further down towards the case base than Dillon or RCBS dies.

Even when I shot USPSA matches with 40S&W as my match caliber, I did not need to push-through resize my brass as Lee carbide sizing die resized brass from my two Gen3 Glock 22s enough to fit even the tighter Lone Wolf barrel chambers.

9mm brass shot in Glock barrels resized with Lee carbide sizing die will fully chamber in my KKM and Lone Wolf chambers. If I can't resize a case (which is rare), I will rotate the case 90 degrees and resize again. Any that still won't resize fully and fit the tightest chamber of my barrels gets culled for recycling.

Take a look at below comparison pictures of 9mm brass resized in Lee sizing dies - I am quite happy with the way brass are resized with the taper - cases are resized without any signs of carbide ring rubbing at the case base.

I load 9mm mixed brass, "once fired" and range pickup. Bullets are 135 and 147, so they seat pretty deeply.
Standard press setup is Dillon sizing die, Lee Carbide Factory Crimp Die.
I gauge 100%. The minor rejects go to practice and shoot normally. The major rejects... well, I haven't had a really grossly deformed round lately.

I do have a "U" die but only use it to get a good "Coke bottle" with my defense practice loads of 115 gr JHP.

There are two "U" dies, Lee and EGW. Lee makes the die for EGW but it is not the same as under their own label. I think the Lee is a bit smaller I.D. and the EGW has a smaller mouth radius.

I have read on the Internet, and therefore it must be so, that you can "bulge bust" 9mm P with a Makarov CFC die body.

I do recommend lubing your 9mm brass with case lube prior to sizing in whatever die you plan to use. Sizing became effortless in my carbide dies, where before, with dry cases, sizing would bump the powder out of the Dillion powder measure.

Yes, a big help. And some guy says on the internet that you don't even have to clean the lube off the ammo.

I just gauged 400 rounds of 9mm loaded in true once fired brass from a government agency's range.
One round sticky in the gauge.
That is very different from the usual mixed brass I can scrounge after a match.

A small-base die will not reach any further down the case than a standard die, so going to a smaller die is not your solution.

And push-thorugh dies, which can reach all the way down to the web of the case, don't work very well on tapered cases, so I don't think anyone makes one for 9mm.

Brass shot in an unsupported chamber has been displaced well beyond specification and there are no readily available tools to "fix" it, so I recommend brass fired in an unsupported chamber be disposed of.

Must be a very wise person. Ahem.

I have ammo cans full of 9mm that I lubricated and fired with the lubrication on the cases. Works fine, in fact, works better than fine because the cases extract and eject more positively.

Now I don't know why, but sizing 9mm cases is sort of like getting the cork back in the wine bottle, a bugger. But, add a bit of lube to those cases and they just glide in the die.

For the small price of $850 you can buy an industrial strength roller sizer from Case Pro at http://www.casepro100.com/desc.ydev?prod_id=33744




This is the sort of equipment needed when a small base die won't work. I wonder if it can press coal into diamonds.

The usual Pacific T-slot shellholder is standard at .125" deep. You cannot size any farther in conventional equipment. BUT, there is also the die mouth to consider, the entry taper or radius varies brand to brand. Dillon dies have a wide mouth for smooth progressive operation. Lee has a smaller mouth and sizes a bit farther down, the EGW/Lee a bit farther still. The CFC die leaves rub marks to within .200-.220" of the head.

And push-thorugh dies, which can reach all the way down to the web of the case, don't work very well on tapered cases, so I don't think anyone makes one for 9mm.

As I said, there has been some work using a Makarov CFC die body as the push through for the Bulge Buster on 9mm P. Some say it helps, some not.

There ARE "readily available tools." There are push through Bulge Buster types from Lee, Redding, and Case Master, $30 to $6000 depending on your volume. The Case Pro roll sizer is popular with USPSA shooters to iron out their racegun empties, as shown by Slamfire.

Or they use .38 TJ brass, which is .38 Super with a huge extractor groove so that the sizing die can reach the entire sidewall.

I would be wary of fully sizing .40 cases out of Glocks et al, but the 9mm does not worry me. But 9mms are generally well managed by U die and/or CFC, and are cheap, so I don't see the point in individual processing.

Newer Glock 9mm have supported chambers in 9mm they do not "bulge" the brass.

With the amount of 9mm brass out there if you find suspect brass why even bother with it?

I mark my brass and do not pick up anyone elses. With several 5 gal buckets I do not need it.

And Yes I use all LEE dies and they work,

FWIW I've come to prefer the U die over the FCD for my 9mm rounds. Certain brass, CBC comes to mind, when run through the FCD on a 147gr round will actually "bounce back" and virtually eliminate neck tension. The FCD actually swages the base of the bullet and the case won't maintain tension at that reduced diameter. I bag my complete rounds and I've actually had rounds using that brass actually come apart in the bag. Doesn't happen with the U Die.
