Question about powder measure?

[slowr1der]

So this is about the RCBS Uniflow powder measure. In the manual for it it says to run a pound of powder through it to get all the film and stuff out. My question is after running this powder through can you put it back in to use it to load your rounds. Or does it contaminate it? I'm just wondering if it wastes a pound of powder or if you can still use it?

First you clean the parts with thinner to remove the grease, then assemble and run powder through, which lubricates the cylinder. If you get the grease out first, you can re-use the powder.

You can still use it. My understanding is that it is not so much to get the grease and such out, but more for the purpose of getting the powder in: coating all internal surfaces, etc. This increases the consistency of your subsequent charges. I would run a full hopper through, put the same powder right back in the hopper, and go to town.

I think you will like that measure. I have a quick-change version of the uniflow, and it has been great.

The main purpose to running the powder thru it is to coat everything with graphite. This will lubercate the measure. The powder is still good.

Disasemble, clean, reassemble, run a half a hopper through it and call it good. Dump the thrown powder back in the bottle, mix it up and load.

I use some graphite as well, coat obviously accessible surfaces right off the bat, then run the powder through to get the ones yhou can't.

Heck, I'm not going to throw powder away if it will still light off!

Go to the hardware store and buy a Graphite "puffer" tube used to lubricate locks.

Use clean & use that first and running a pound of powder through it would be a waste of time.
