I bought a new in the box Redding Match Grade 3BR Powder Measure This is an expensive tool. I took it apart because I could see rust on the naked iron in some places.
A little scrubbing with very fine oiled steel wool removed the rust.
Reddings instructions say to never oil it. So how does Redding expect it not to rust? It’s iron, iron rusts. I wipe off the oil prior to using this machine. After use I wipe it off again and re-oil it.
I also dispense black powder with it, works great with BP even though Redding says don’t use it with BP. Redding is probably worried about iron parts clunking together and spark. The measures parts never clunk.
Anyone else oil their iron frame Redding powder measure?
