Sizing .40 S&W brass that was fired in a Glock
I have a several thousand 40 S&W cases that I am going to reload and shoot in an H&K. I have found that .40 cases that are fired in a Glock are shaped a lot like Hillary; kind of pear shaped. Since the case is small, if you use a normal resizing die and shell holder, nearly 1/4" - 5/16" of the bottom of the case does not get sized. Enough to prevent the case from entering a normal sized chamber. Although, I have not verified that. I have thought about un-screwing the decapping pin/holder and removing it from the sizing die. Then using a ram to push a fired case flush with sizing die and then using a wood dowel to tap the case out of the sizing die. Yeah, this would be slow, but I can't think of any other way to size a "Hillary shaped" case back to normal dimensions. Any suggestions?

I don't know why the brass would not go fully into the resizing die unless there is something really wrong with the brass. I have reloaded many of thousands of rounds of .40 for Glocks, HK's, etc., and have never encountered or heard of what you are saying. If the die is set correctly, and there isn' any problem with the brass, it should resize just fine. It sounds to me like you need to set youe rsizing die lower in order for it to resize that rest of the case. A picture would be nice, to see exactly what you are talking about, because I am just not picturing it in my head.

I agree. I have reloaded many thousands of 40 that have all been shot through my Glocks without any problem whatsoever. Do you have any photos?

If the bottom of the size die is 1/4" above the shellholder at the top of the stroke, 1/4" of the case is not going to get sized. |

Get and EGW Undersized Die
The EGW undersized die works pretty good for me on the Glock brass.

Easiest way is to find a commercial reloader in your area and have the brass roll-sized. That will bring it to factory spec all the way down to the rim.

I read something about the "Glock belly", but I can't remember where. I like the Hillary thing better.

Roll sizing sounds the best, thanks. When using a normal sizing die, (I'm using "New" Hornady dies), the mouth of all the dies has a small bevel (bell?) to facilitate the case entering the die easier, especially in a progressive press. This bell mouth is about 1/8" long. The shell holder holds the case by the extractor groove on the case, or course. The distance from the extractor groove to the top edge of the shell holder is about 1/8" as well. With the shell holder firmly seated to the base of the sizing die, this gives a good 1/4" of the case that is not sized. The smaller the case, the more this is a factor. A really short case like a .25 acp only gets sized about 1/2 the length of the case because of the limitations of the shell holder and sizing die.
I have a S&W Model 59, 9mm that will not chamber a case, that has been fired in a Glock and resized using normal loading dies/shellholders. There is a "Hillary shaped bulge" just in front of the extractor groove, that doesn't get resized that prevents the case from chambering. It's difficult to see with the naked eye but, check the case with a micrometer and you'll see what I'm talking about. I had a heck of a time with reloaded 9mm shells not feeding in my S&W until I miked the cases and found the problem. That's the reason I asked the original question. I haven't check my H&K yet. |

I've re-sized plenty of glock .40 brass. I haven't had any problems with it not chambering

I use the EGW dies. They work good and also help with bullet setback.

Like others have already said, I've reloaded .40 that had been fired in glocks for years without a problem using standard RCBS carbide dies.

Like above, I haven't noticed any problem with re-using Glock brass in any of my .40 pistols, but I have a Lee Factory Crimp die at the final stage on my Dillon turrets.
