Go easy on me moderators this is my first post.

Problem: Glock fired brass has a buldged base due to unsupported chamber. When sizing through Dillon dies the die does not go right to the base. The round is loaded however sizing is not to factory spec and has the potential to cause failures to feed.

Solution: Come up with some type of contraption to feed the casing all the way to the base in a single stage press and resize to reloading manual specs. Please see the pictures. I have resized over 20,000 rounds with this (thats why you see the string to the counter). It is the one reloading job you can almost do while watching TV, only one black thumbnail. I have fired 6000 rounds since mid December in my Para and no failures to feed due to sizing. Four due to failure to remove all bullet grease though. By placing the casing on a flat surface, you are able to advance the casing all of the way in to the Lee sizing die. The rod is then needed to expel the casing from die. I used Lee because they do not have the tapered base in the die like Dillon. Warning if you decide to make one up without instructions just make sure you use spray lube on casings. My cost was one shell holder that had to be welded on the flat bar and a piece of threaded rod with nuts, one long bolt and flat bar from the scrap pile.

If there is interest I will post construction instructions.

Glock brass needs to be roll sized. I am not sure what your contraption is, but a single stage press for pistol shells is nothing short of slow and inefficient.
And most of us use carbide dies to eliminate the need for lube.

good work though....
 
I use carbide dies. I am aware of the roller but don't have spare $400.00 plus to buy one. It is slow but does not have to be done again as long as not fired in a Glock again. I just wanted to get the brass back to specs in manual. I was not suggesting failure to re-size would cause a K boom. Just trying to help those that may have feed problems with otherwise usable brass. Some say they never have a problem with Glock fired brass but mike it against specs in manual at the base. Just a suggestion. The lube is just to speed things up a bit. Plus that last little bit of push to resize the base is significant. I still load with a Dillon 550 after.

You need to rethink your $400 price tag on the roll sizer. I have one with 3 die sets and have over $1000 into it.

I roll sizer all of my brass now, and have not had any chambering problems.
 
A set of Lee carbide pistol dies (along with a Lee carbide factory crimp die) keeps my Glock 21 perking along just fine (and for a lot less ca$h than a roll die).

I agree with Shootshellz. Buy a carbide Lee Factory Crimp Die and that should solve your problem in bulged brass.
I get a lot of Glock once fired brass from my range and never had problems reshaping and reloading them to its "original" form using FCD.

Good Luck, reload safely. :)
 
I used to have problems resizing .40 brass. To me it appeared that not all of the case was going into the die.

What I did was to use my standard Lee turret press & Carbide resizing dies but I ground down the shell holder to allow more of the brass to go into the die. It worked for me.
 
wheelgun,

You can buy a die that is shortened just for this reason, to get the buldge sized. Years ago I posted pics of my method. I simply push the case through a Lee factory crimp die that I polished to my size I needed. The "pusher" placed in the shellholder is the punch out of a 9mm lead sizing die set. I cut out the lip in the red tube so it will fit and sort of thread over the die.
Here are some pics

Simple resize .40 Glock fired brass in a Lee Undersize sizing/decapping die (p/n# 90620). It was designed to size the case all the way to the bottom, works great in a my Dillon 550B loader. Otherwise I use regular RCBS Carbide dies with a Dillon Crimp Die, just make sure you do all your sizing in station 1 with the Lee die and you'll be fine.

I've loaded thousands of reloads, using the same cases, fired from the same Glock pistols this way, never an issue with out of spec ammo, it all chambers and goes boom when the trigger is pulled.
