9mm cases not resizing all the way
Quote from Reloader on July 23, 2013, 1:24 amQuestion:
I got my 550 all set up yesterday. I adjusted my resizing/depriming die like it said to on the DVD and resized a few cases (I also played with the flaring die). That slight bulge at the bottom appears to be from the resizing die not going all the way down the case. I measured an unsized/once fired case and it was the same measurement from top to bottom. Then I resized it and it shrunk down everywhere except where that bulge is. I don't know what's wrong and why it's not resizing the entire case. My resizing die makes very light contact with the shell plate when the handle is completely down so I can't go any lower on the die. The resized brass easily fits my case gauge though, even with the bulge.
What am I doing wrong?

Quote from Reloader on July 23, 2013, 1:41 pmBe advised that some 9mm brass shot from a Glock will not resize properly. I have been told that a bulge at the bottom of the case is the culprit and it is because the Glock does not chamber the round all the way (or so I have been told). When I run across these brass I just chunk it in the trash. I also check every reload with a Dillon precision case gage just to make sure they will feed properly.

Thanks
