Glock brass won't size correctly

Just got my Dillon XL650 setup. Went through the manual carefully. I ran a couple of test reloads before powder/primers. I'm using 1F indoor range brass, mostly from 9mm Glocks. I know that Glocks have an unsupported chamber, so I was looking for this problem to come up. Well, it did. I readjusted the sizing die. Still unable to get brass back to straight wall. Can easily feel & see puffed out section on brass (see pic). Tried to feed a couple in to my Shadow. Had to manually force slide forward 1/16". Using Dillon dies.

My Questions:

Am i not adjusting the sizing die down enough? It touches the plate when raised. When the plate is raised to size & de-prime, you can feel the tension in the arm.

Do i need to size on a different piece of equip (Rock Chucker ?), then load into Dillon?

Use different Dies?

Use different Brass?

Thanks in advance.

Do the rounds feed and chamber reliably? If so, I wouldn't worry about it.

I don't know of any die that resizes all the way down to the groove...
 
hmmm, I don't know what to tell ya. Hopefully someone will come along with more useful information.

I use Lee dies and have successfully reloaded many a Glock-fired case. They sometimes look a bit kooky near the base but they've always fed reliably.
 
I have reloaded 1000's of .40 glock brass using dillon .40 dies and fired them from my Para. Zero problems to date. I have heard of people turning a few thou of the bottom of the die, pretty sure you would be limited by the carbide insert.

If you know someone else with a 9mm die, maybe you could borrow it to verify your die is doing it's job.

Just throwing ideas out.....
 
Use the Lee Factory Crimp die not the Lee crimp die. It will full length re-size your reloaded round.
Good luck

+1 The Lee FCD has a carbide sizer that sizes the finished round. The die mouth radius is smaller than on some sizer dies so it sizes closer to the base of the case.

I had a batch of 9mm factory reloads that wouldn't feed well in one gun with a tight chamber. Ran all the remaining loaded rounds through the Lee FCD and problem solved.

So use the Lee Factory Crimp die in the Dillon station #1, or use in a seperate press to re-size first, then run through the Dillon?

Or use the Lee Factory Crimp die inplace of the Dillon Crimp die (station #5) ?
 
There are only two solutions that I know of:

(1) Have the brass roll sized, or purchase a roll sizer, I owned one for a time but it was a lot of extra work.

(2) Buy a Lee carbide factory crimp die, and use this on the last stage of the press. This is much easier and can be used to fix the cartridges in the picture. Since I removed my Dillion crimp die and replaced it with the Lee die I have never had a problem, and that was 10,000 rounds ago!

Keep in mind that 9 is a tapered case...so that's not unusual. My 9 major reloads all have a slight "waist" in the middle...and I dont have any feeding problems. Yours do looked slightly bulged by the case head...but it's hard to tell from the pic.

Are you chamber checking them? If you don't have a chamber checker...just take the barrel out of your gun and use that.

Feeding issues can be a mystery sometimes...best to eliminate the variables one at a time...

Cheers
 
.40 glock fired brass - the cure

Cortland, NY….. Redding Reloading Equipment has always responded to the reloading market’s needs with innovative and high quality solutions to the unique problems encountered by the dedicated handloader. One such problem is that of the bulged and often unusable, fired cases produced by some the most popular current autoloaders in the 40 S&W caliber. With the current high cost and difficulties in obtaining brass cartridge cases, the market needed a method to restore these cases to reliably function when reloaded. Normal sizing dies do not resize the bulged section as it often extends into the web area of the case.
Redding Reloading Equipment responded by designing a unique push through die, which fully resizes the bulged area of the fired case back to within the accepted SAAMI specifications for case diameter. The case may then be resized in a standard sizing die for the remaining reloading process.
The Redding G-Rx die set is comprised of a pusher rod which fits into the ram like a shell holder plus the unique push through sizing die with lock ring. To use, the case is set on top of the pusher. Then the ram is raised to push the case entirely through the die. The die has a rebated section at its top to hold the finished case so that it may be easily removed. With the Redding G-Rx Die Set you can remove the bulge from literally hundreds of cases per hour preparing them for the reloading process.
Redding offers numerous unique solutions to improve the accuracy, consistency and reliability of your handloaded ammunition. For more information and a current color catalog contact: Redding Reloading Equipment 1089 Starr Road Cortland, NY 13045, or visit us on the web at: www.redding-reloading.com.

I have the same problem with my 650 but its about 4 or 5 out of 100 re-loads.

I check every single one with case gauge - the ones that didn't chamber in the gauge are used in my 9mm AR that chambers them no problem.

I have a Lee Factory crimp die that I should try instead the dillon crimp die in station 5.

Thanks for the info.
 
The Dillon resizing die won't go down far enough on the .40cal case to get rid of the Glock Bulge. The Lee Sizing die will and can be mounted in your 650 press. I use the die for reloading Glock shot .40cal brass and have had no problems chambering the rounds in my Tanfoglio. The Dillion 9mm resizing die works fine on Glock shot 9MM brass.

I don't use the Lee FCD as I shoot lead and resizing the lead bullets to less than 1/1000th over bore does not make any sense to me.

Take Care

I concur with the mule....new Redding die, and i don't know where i say it advertised, is meant to deal with this, the cases passes through die completely. This is similar to "base forming dies", except base forming dies are usually meant for case reforming.
 
The redding die looks interesting.... but the Lee FCD solves the problem (unless you're loading lead, as Canuck44 pointed out) and is much faster as it's done right on the progressive.

I use a Redding 9mm sizing die, cranked right down - it does the trick. But if it didn't, the FCD would come out.
