Ed K Posted January 25, 2015 Share Posted January 25, 2015 Need some help/suggestions please. Set up my new SDB and cases are bulging within bullet seating depth, after crimp. I'm using a hundo and a Lee case gauge. I've gauged after the resizing die & they're fine. Prime, powder, case flair. Won't fit. (Of course) Bullet seat. Won't fit. (again of course) They don't fit in gauges after crimp. Also don't fit it gun. STI Trojan. .40 Cases: Mixed brass. I've sorted by head stamp and no difference. No Glock bulges. Bullet: Xtreme 10/40-180 RNFP HPCB OAL: 1.135 They are gauging at .422 consistently. Thanks Ed Link to comment Share on other sites More sharing options...
Youngeyes Posted January 26, 2015 Share Posted January 26, 2015 Pull out the crimp die and reset. Bring it down slowly and keep checking to see when it case gauges. Did you set those dies or did you just use the machine the way it came from Dillon? What part of the round is hanging up in the case gauge? On second thought, reset all the dies. This way you're sure. Link to comment Share on other sites More sharing options...
Ed K Posted January 26, 2015 Author Share Posted January 26, 2015 (edited) I'll give it a try. I used the crimp setting from factory. Ed Edited January 26, 2015 by Ed K Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted January 26, 2015 Share Posted January 26, 2015 I wouldn't reset the crimp if it came from the factory - just my personal experience. I'd check the OAL 1st. Possibly too long for that particular bullet in your gun. Link to comment Share on other sites More sharing options...
Ed K Posted January 26, 2015 Author Share Posted January 26, 2015 OK, got it narrowed down. The cases are being over flared at the powder die. If I bypass the priming/powder stage, seat & crimp bullet, they gauge fine. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted January 26, 2015 Share Posted January 26, 2015 The cases are being over flared at the powder die. I'm not sure why that would be any kind of problem other than working the brass more than necessary. The "crimping" die should remove all of the "Over flare" and you should not have a problem??

Ed K Posted January 26, 2015 Author Share Posted January 26, 2015 Fixed it this AM. I adjusted the flare a bit smaller, and it works. Thanks to all. Ed Link to comment Share on other sites More sharing options...
Mikelindsey Posted January 26, 2015 Share Posted January 26, 2015 (edited) Glad you got it fixed. It seems that 40s people just have problems for some reason. I know when I do 40s, it's never problem free. Like on my 650, I throw on the 45 stuff and the only thing I have to remember is to place the bullet and pull the handle. Never had any probs with 45. Also question for the responder above. You say stay with the Dillon set up for the flare. I may be wrong but it seems to me that is the first thing I would check and readjust. Dillon is good but when stuff ships it can get bumped out of specs. Am I wrong there? Edited January 26, 2015 by Mikelindsey Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted January 26, 2015 Share Posted January 26, 2015 Also question for the responder above. You say stay with the Dillon set up for the flare. I agree with you, Mike, for the flare, but I find it has not been necessary to tinker with the factory set up for the "crimp". That's been my experience, anyway.
