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?
