What causes the powder to clump up?

    I'm using a Lee Deluxe turret press with accur #7 powder. The tube that leads to the case gets clogged up. Just to the point where the walls of the cylinder are covered. It almost looks like it's gotten wet (which is imposable). Is this a normal thing? Is there a way that I can fix this? Thanks.

    Sounds like humidity. The powder is getting wet. Or it may be static electricity?

    Disassemble things so that you can clean the tube with a degreaser, dry well and then run an anti-static dryer sheet through the tube. That should take care of any clogging.

    Car Knocker hit the nail on the head - it's static.

    Well, actually, my suggestion covers two bases. The information provided in the original post doesn't tell us how new the equipment is and experience has shown me that oftentimes new equipment has a film of manufacturing oils or other agents on it; therefore a degreaser is called for to eliminate that possibility. It also just doesn't hurt to clean things; the feed tube is going to have a graphite coating on it from the powder.

    The second thing that comes to mind is increasing static buildup as the powder flows across the feed tube at speed. That calls for the anti-static dryer sheet. These sheets are also handy to remove static cling from the inside of the powder measure reservoir and used sheets (torn into strips) in the tumbler help keep the toxic dust down to a minimum. Just throw them away as they get dirty. A couple of used sheets can also be used to dust off the equipment - it seems to keep dust from settling again quite as quickly.

    More helpful household hints to follow! :cool:

    Thanks for the help. This is the first time I used this press and it's the first time I've reloaded. Thanks again.

    I just reloaded 50 9mm after cleaning everything and running a dryer sheet threw it and there was about 2 specks of powder in there. So I'm 99.9% sure oil was the culprit.

    Glad the simple solution worked.

    I know you have corrected the problem, but I just felt like adding my solution to the list...

    On my reloading equipment, I use Hornady's One Shot spray lube. It will remove all the oil and moisture, and when it drys out it leave a dry lubricant. It works especially well on dies too.

    Dry lubricant? Nay...A wax residual, but not dry...:) Powder will stick to it. It will probably work on those dies that have nothing to do with powder drops such as Lee's through powder charging die.
