Little Dandy Rotors have powder sticking

[gsdelong]

I am having a problem with powder sticking in the chamber of several little dandy rotors with 296 this is really bad.

I have tried acetone and brake cleaner thinking it was an oil or some other surface substance causing the issue, and this has not fixed the problem.

When I remove the rotor and inspect there is powder stuck to the surfaces of the cavities

Any advice and help would be appreciated

Yes. Do not use 296.

With the little dandy or at all? Could/Would you please elaborate?


Yes. Do not use 296.

The small particle size of 296 is partly the problem, but a contributing factor is that 296 is not graphited to reduce static electricity.

So ALWAYS attach a static ground wire to your Little Dandy powder measure and loading bench!

GOOD idea for ALL powder measures!

Essential safety precaution for ALL progressive machines to prevent primer tube explosions!

Also very highly recommended that you lightly coat the rotors and drum cavities with powdered graphite to dissipate static electricity!

Use a fabric softener dryer sheet on the plastic powder reservoir.

These precautions will prevent powder from "sticking" and mitigate the risk of unpleasant surprises in the loading area.

This is standard safety procedure in all industrial areas in working with flammables and explosives!

Have you tried cleaning with rubbing alcohol then running powder graphite through it? I do that with all my drum measures and stops powder from sticking. I have issues where I'm at in the winter as it is really dry and 296 was the worse for that but after doing the alcohol and graphite treatment it stops.

I wonder how many loaded cartridges you may have right now that are loaded under the recommended minimum load factor.
296 is one of the powders that will get you into trouble quick going under min. load by, I think...3%.

I have switched to using the charge master for these loads. Thanks for all the input

Interesting information. I have tried drier sheets and that alone doesn't quite do it. I have 3 powder measures and will try graphite with all of them. Thanks
