I have seen and heard of some coating the inside of the powder hopper on the measures to make it flow better and have more consistent drops. What are you guys and gals coating the inside of your hoppers with if anything, how much does it cost, and where do you get it? Thanks.
 
Never heard of any coating for inside a powder hopper. I have heard of people wiping down the outside of the plastic with an anti-static cloth. I suppose that could help get rid of some powder clinging to the sides.
 
Used clothes dryer sheet for static.

Powdered graphite as used in locks is also sometimes used.
You can get a small tube of it at an auto parts store.

Powder has graphite on it to make it flow better.

You can take the plastic hopper off, at least on the Lyman 55, and dip it in slightly soapy water (Dawn or the like, not a detergent) and let it dry without rinsing. I've never tried to take the hopper off my RCBS Uniflow, but the instructions suggest it is removable... On the metal parts, wiping with the dryer sheet is fine, or a dryer sheet with some graphite.
 
I think what you are getting at is using a baffle. This is a baffle if this is what you are getting at. You can buy one for your hopper or as can be seen, not much to it so roll your own. I use them and like them. Obviously a baffle isn't a coating though. The idea is more consistent and uniform powder drops.

Beyond that the drier sheets have been covered as well as RC's post.

I've never done it. Just wipe it out with a rag every time I change powder.

I did have to change the hopper on my RCBS Uniflow when, after 25 years, the powder had really etched it pretty badly. (Not supposed to leave powder in the hopper for long, especially with high nitro content powders like Bullseye, Unique and 2400, which is about all I use, except for rifles. But...:)) RCBS gave me a new hopper for free. If you ever do change the hopper it can be a real pill, until you view the RCBS video on youtube. Neat trick.

Me, too.

I wipe down the hopper of a new powder measure with the dryer sheet and I store the dryer sheet in the hopper when not in use.

After a while, the graphite used to coat the powder kernels builds up enough on the powder measure where the dryer sheet is no longer necessary.

I never get any water near my powder measure. If I wipe out the hopper, it I wipe it with a dry towel. But to each his own.

I know you weren't trying to argue the merits of baffle use in your post, but isnt their some debate as to if they really have any effect or not? I thought I caught a glimmer of an article about it as it flashed by my screen once.
 
I think we may be talking about powdered graphite. Run it through your powder measure and nothing sticks to the inside. Since graphite is already in smokeless powder, you don't have to worry about contamination.
 
Thanks RC. I did Google it once and all I could find was the mineral on wiki and this:

Missouri Information for Community Assessment :)



How would you go about applying it? Dip the case mouth in? Someone PM to avoid the hijack.
 
Spray bullet mold release is an effective anti-static cling coating, but it is opaque so you would not be able to see the level in the hopper. I only use it on plastic powder scale pans.
 
you can buy powdered graphite at Ace hardware for very little. They use it for keeping locks from freezing up.

I use it...it works

Don't want to get off topic here or hijack this thread as to coatings but my observation using a RCBS Uniflow was the baffle helps. Does it really make for more consistent and uniform drops? When I ran some test it seemed to follow with the theory behind using it and since I had a few I had nothing to loose by using one. They can also be made easily.

Normally I would drop just a little light in for example 50 cases. Then each charge dumped on the scale and I use a trickle for the final weight. Out of curiosity I noticed when using the baffle if I started dropping 45 grains of powder in 30-06 cases every time the drops went on the scale they were tight with very little deviation. Figure too the powder type plays a roll in things.

Picked up some today from A.C.E. hardware for $1.96 counting tax. I needed it for something else but if it will work on a hopper I will use some on it. I don't think I was talking about baffles. The video that I saw the guy sprayed the inside of the hopper with some type of graphite and less it dry before using it for the first time to prep the hopper. I had read in different places where some had also coated the inside of the hopper before using it with various lubes. All of the claimed it improved the throws so they were most consistent that is why I was asking about it before I start using my auto disk measure. I finally have time and room to do up some rounds after removing a book case and rearranging my room so I could steady up the bench some.
 
PB Blaster makes a spray graphite. It works well although it will make your powder measure's hopper black.
 
You DO NOT want to use graphite spray lube inside your powder measure.

Dry graphite powder is what smokeless powder has on it.

And a small puff of dry graphite powder as used for key locks is all you should ever put in it.
Besides powder.

Thanks RC. I don't use spray graphite anything, I don't even have any so good thing you told me before I bought some. I use gun slick or straight powdered graphite on my moving parts like the slide and the graphite I bought today is AGS extra fine powdered graphite lubricant.
