I am going to apologize in advance for a dumb question but I can't seem to find information anywhere. I have the RCBS Uniflow Powder Measure and had to temporarily store it in the shed. It got a little bit of rust on it so I decided to clean it with White Vinegar to get it off. I noticed the drum has been stripped down some as a result. What should I put on it to lube/oil it that won't hurt effect the powder? I'm fairly new to reloading still so any help would be greatly appreciated.
Thanks!
Thanks!
