spook Posted January 30, 2008 Share Posted January 30, 2008 OK, I have spent quite some time in the search function reading up on the bulged cases and how to get rid of them. But I couldn't find what I was looking for. I have a SDB in 9x19mm and I load 9mm minor for my stock Glock 17. Lately I get a lot (15%) of rounds that will not fit the chamber. The rounds have a ring/buldge at the bottom of the case (about 0.1" wide) that doesn't seem to get sized. I acutally get Failures to Extract when these out of spec rounds end up in my magazine after the first shot. It takes a lot of force with a squib rod to get them out. My extractor can't get them out. It will damage the rim before it extracts and slip over. Now I have a feeling it has something to do with some 9mm major brass that I pick up at the range (I shoot with a couple of guys that shoot 9mm major), combined with my SDB not fully sizing. I have looked at solutions, but the only ones given here are either roll sizing or the EGW U-Die (which doesn't fit the SDB). I wonder if anyone has ever modified their SDB to get the sizer lower (adding rings to the top of the die and/or grinding the die down to the sizer ring). There's still a lot of light between the die and the shellholder when the ram is up, so I figured I could win some there. Any suggestions to get rid of this problem are welcome.
