.308 binding in sizing die
Quote from Reloader on June 26, 2017, 10:32 pmOk, so been loading now for over 6 months, have produced over 10,000 rds of .308, .223, 9mm and .357 Sig with no issues, till today. So I am in garage earlier, just finished converting machine from .223 to .308, I have dedicated tool heads for each caliber, and I also have the mounted with Unique tool head clamp kit, so no head movement issues. So I take 10 .308 brass, they have been tumbled cleaned and dried for over a week, I dip each into imperial dry neck lube, drop them into feed tube and start process. 1st round tight, but makes it to station 2 where primer seats easily, set my Varget to 42 grain, then roll from there, 5 rounds are tight using Imperial, but each perfect, then I get to the 6th round, it's stuck, I fight handle and base comes off off brass, remove from die, reinstall die, and try again, still tight, but now primers will not seat all the way up in brass, 90% seated. So I gave up for now to study, it 108° in garage now and I'm in no mood lol, anybody have any tips as to what IA+A+A+ am doing wrong? And no, I do not want to deprime before tumbling hahaha. I have made over 1000 rds of .308 on this machine before with zero issues, other than some binding from sizing die. Also, I use these in my AR10. Thank you in advance for the help and comments to come.

Quote from Reloader on June 26, 2017, 11:00 pmOk, found some of the .308 brass with seating issues to be the actual brass. Looks like they were loaded too hot, and stretched brass into primer pocket, therefore not letting them seat fully into pocket. So one issue down, now need help correcting the brass binding in sizing die issue.

Quote from Reloader on June 27, 2017, 2:31 amWow, tons of help here!!! Glad I figured it out. Seems that the sizing die deprime pin was adjusted too far down and bottoming out, therefore pushing against primer pocket causing to bulge and not letting primer seat all the way in. Now, how is it that happening now since I have not changed anything since last batch of 308's made?
So sizing/depriming die, how do I set pin height? I removed the pin, swapped out with new pin without the ball and it works fine, no more binding. I have never turned or adjusted pin due to it having the clip, I thought that was proper adjustment, but when it is all the way down, can speed the contour of the pin and that is below the seat of the case. Makes zero sense

I was puzzled by your problem. I read as much as I can to learn something. But I do no rifle loading on the XL650. I was looking at the cut out pics in the catalog and it appears that rifle dies have an adjustable decap pin with an expander ball on it. On pistol dies it is spring loaded and will push up a bit if necessary. But it has no adjustment.
I can only assume that your die adjustment came loose and has worked it's way down and is now causing a problem. I have experienced a couple screws working loose with use. So I suppose that it possible for a die to do the same. Readjust it and tighten. Check as necessary.
Perhaps the folks at Dillon will pop in with a comment today.

Quote from Reloader on June 27, 2017, 3:35 pmThe Dillon size die is a full-length size die. You need to use a lanolin-based lube, and lube the case body. Dry lube on the neck is simply inadequate.
The correct depriming pin adjustment is as the die was sent. The spring clip is in a groove on the upper bolt, the jam nut is up against the bottom of the clip, and the assembly is threaded into the top of the die until the jam nut stops against the top of the die.
Primers are seated at the end of the upstroke of the handle. Be sure nothing is interfering with pushing the handle forward. It sounds like the shellplate bolt may not be tight enough. First, be sure that the ejector wire is not underneath the shellplate bolt. Push down on the edge of the shellplate at station 4. If it feels springy, then the shellplate bolt needs to be tighter. We suggest tightening the shellplate bolt down until it stops, then back it up about 1/8th turn. Be sure to snug the set screw on the left side of the shaft to prevent the shellplate bolt from tightening.
