I am new to reloading and have a Dillon XL 650, I am having an issue when I am resizing my 40 cal cases. I know about the Glock bulging problem with leaving a bulge in the case, but my problem is when the cases are sized it puts a bulge into the bottom of the case, not a huge bulge but enough for the finished bullet not to fit into the case gauge. I thought that i was sizing them to deep so backed off the die then thought i wasn't going deep enough so screwed the die in further, still get the same result. Is there anything else that I should know that i may not be doing right? Keep in mind that these cases look fine before i re-size them after they come out of the die they have the bulge toward the bottom of the case almost near the taper. Am i just gonna have to get the Lee debulge kit and run these cases through it after i size them?
If I understand you correctly, it seems that you may be seating and crimping on the same step. If you are, lighten the crimp a little because that will cause the case to bulge near the head of the case. If you seat in the seating step and then use the Lee Factory Crimp die you will avoid that problem all together.
Also, just a friendly FYI. The correct terminology for a finished round is not a bullet, instead it is called a cartridge. So your sentence would read: I know about the Glock bulging problem with leaving a bulge in the case, but my problem is when the cases are sized it puts a bulge into the bottom of the case, not a huge bulge but enough for the finished
cartridge not to fit into the case gauge. I thought that i was sizing them to deep so backed off the die.
If you watch my youtube video on setting up your dies, you will see how to set up the seating die, and then the Lee Factory Crimp die. I do not know if the Dillon runs off the same die types so I hope it helps. Below is a link to the video.
