Dillon neck expander sticking (45 ACP)

I've always used RCBS dies and presses but I recently picked up a 550 Dillon in 45 ACP.

I notice that on the downstroke, pulling the case out of the neck expander is tough, really sticks. I can wipe the bell die off every few rounds and it's OK but after a few loads it starts to stick again.

Like I say, I've never used Dillon before. I know lots of folks say to use lube even on straight walled cases, but I never needed to do that with RCBS.

Anyone else ever run into this?

This brass by the way is new Starline from Midway, straight from the box. Wonder if there is some chemical on those new cases, maybe I should run them in the polisher first?

Any suggestions appreciated.

I had the same problem with new Starline 38 Super Comp brass. If you have some used brass, alternate between the two and it works.

I get a rare case that sticks. So infrequently I've never bothered to check the headstamp. I'll have to remember to look.

I've only had the problem with new brass. Once fired Starline works just fine.

It is the new Starline brass. After the first firing it should stop. The one Dillon expander I have is nice and smooth, so it probably isn't an expander plug roughness issue.

After having this sticking problem with several of my presses I have finally admitted defeat and I now use Hornady One Shot case lube on my pistol cases. If applied as recommended some of it gets into the case mouth. Also, less jarring of the press makes the powder measure more consistent. It just makes everything much easier. I still use my lanolin based lube for rifle cases but I have to remove it after sizing - not so with the Hornady.

I've loaded thousands of 45 ACP's on my Dillon 550B and have never experienced the problem you're having. However the only Starline cases I have used were in 10MM and they were all once fired cases. If your sizing die is definitely a carbide die and is "squeaky clean", then I would call Dillon customer service to get their advice. It could possibly be a defective die.

From Dillion's forum > Some sticking with new/once-fired brass is not unheard of. Wipe off the funnel with steel wool or a scotchbrite pad every 25-35 cases to prevent brass buildup on the funnel. Be sure to tumble your brass, that helps also. Usually by a couple of firings the interior of the case is smoothed out enough from the repeated firing to eliminate this. It also could be that the S&B brass is slightly thicker than other brands. Normal neck thickness is .009"-.011". http://www.dillonprecision.com/45_cases_stick_to_powder_funnel-98-11-802.htm I am using standard Starline 45acp brass on a Dillon RL450 with there expander/powder die, no problems. Other dies are RCBS. Is the problem with the standard brass or the +P? +P is thicker/heaver brass in the web area so Starlline has said on there website. http://i338.photobucket.com/albums/n420/joe1944usa/Firearms%20%20and%20%20Reloading/th_DillonExpander2.jpg (http://s338.photobucket.com/albums/n420/joe1944usa/Firearms%20%20and%20%20Reloading/?action=view&current=DillonExpander2.jpg)

if you reload Starline brass, Starline will modify your Dillon .45acp powder funnel, free of charge, so that it will work easier.

Why is it very hard to get expander and powder funnel back out of case?
There are two situations that create this problem. The first is one we have just recently identified. It seems to be associated with the dillon powder funnel and only a couple of calibers (45 Auto and 40 S&W). The land for expanding case mouth is too long and when you begin to bell mouth the bottom of expander gets into the thicker taper of case and wedges causing it to be very hard to get back out. We have modified several by increasing radius on end and slightly shortening expanding land and this eliminated the problem completely. Call Starline and we will take care of it if you wish. One other cause can be a burr at case mouth created by the final trim operation, which grabs onto expander as it comes back up. This situation does not often appear and can be fixed by deburring case mouth or inside lubing cases.
