Hornady Powder Measure Rust Prevention?

[G11354]

My Hornady LNL powder measure has some slight rust spots on the rotor.

Any suggestions as to rust prevention seeing as oil is clearly not an option?

A rolling rock gathers no moss, and a well used powder measure gathers no rust. In all seriousness I wrap mine with the paper that it was shipped with after use. It asorbs moisture keeping it from the measure. The best option would be to remove the rotor after use and store it in controlled conditions.

I spray mine with Hornady's One Shot case lube. It is basically a wax anyways and mine has been in a constantly humidy controlled 72 deg since I took it out of the box when I bought it. It still has two finger prints very lightly rusted into the side of the rotor.

We are told to clean and degrease the rotors and body of measure when we unpack them per Hornady's instructions and hence they tend to rust. I cleaned mine again when I saw it starting to rust, then sprayed it with One Shot and it hasn't rusted since.

One Shot dry lube and gun cleaner or Boeshield T-9 for long term storage.

I run a dehumidifier in my shop 24/7. Nothing rusts.

When I first got it, I began to have problems with irregular powder throws. Turns out I lowered the humidity too much, and the powder was developing static cling in the hopper. I raised the RH by about 10% and all is well now.

Hornady One Shot Gun Cleaner and Dry Lube works pretty good. The trick is to not handle bare metal parts with your bare hands, and if you do clean it quickly. Nitrile gloves come in handy and are cheap, they're also good for handling lead (as long as it's not hot).

Greatly appreciate the help everyone! I'll spray the parts down and see what happens.

My Hornady LnL is about 1 year old. I have three humidity gauges in my space. With a commercial dehumidifier going I keep the humidity 45-55%. i too have some rust showing on the ends of my powder dispenser. I use Hornady case lube constantly on everything. As far as I am concerned this is a cosmetic defect. At least that is what I hope it is. I do feel better knowing you have the same problem.

Same here. I cleaned the parts really good when I got the press. Not long after the rotors, the adjustment knob, and the baffle all got surface tarnish. I apply One Shot heavily now and it hasn't become worse. I cleaned some off with 0000 wool and will probably try a soak at some point.

I did a copper plate job to the rotor on mine, makes it smoother and protects the steel. But it eventually wears off since the CU plating is really soft. This was just a test to see if it would keep it from rusting, it did for several years. Just noticed since I moved that I have rust on it again, it's been in storage. I need to clean and apply a heavier coating this time.

Can't easily oxidize if oxygen can't reach it.

I like Break Free.

On a powder measure, only the lightest coat.
Will not harm your powder in tiny amount.

The sizing waxes sound good too.
