Powder Funnel Damaged ?

Howdy,

I just started on a new batch of once shot brass (for sure once shot single headstamp) and my brass gets stuck on the powder fill station as the powder funnel that does the "bell" does not want to let loose of the brass. I have had to forcefully yank on the handle to dislodge the case from the funnel.

It just started happening yesterday and I had to put a little lube every 4-5 cases or it gets stuck again.

Do y'all think I scratched that bell part and it needs to be replaced?

Someone else posted this problem in a prior thread:

" The powder drop tube that funnels powder and bells the cartridge is very tight and theres lots of friction and scoring on the tube during upstroke."

It is a pistol die and the suggestion was to clean with scotchbrite or similar. On my funnel I see small vertical lines, I assumed they were scratches on the funnel.

With Pistol cases, if the cases are cleaned too well, then there isn't enough carbon on the inside of the case to act as a lubricant on the funnel. When i first started loading, i tried to get them spit polish shinny, and it made for a hard go. I backed off a little and they flow like water through the machine.

I took my powder funnel out and chucked into my drill press and polished it with very fine emery cloth below the taper/bell area. Since I have done that, I don't have any sticking of cases on the powder funnel at all. Whether it be new unfired brass or brass the has been wet cleaned.

Wow, I am running into this problem right now. Actually, I just called dillion and they sent me a replacement funnel because my vertical lines were literally deeply scarred into the funnel.

So basically the issue is that the brass is "too clean" and needs to have a little bit of left over fouling to make it smoother? (I use stainless steel pins and deprive them before cleaning so the flash hole gets cleaned out too)

Something besides clean or dirty is not the issue here , saying that you need to keep your brass with some carbon on them to make the die work properly makes no sense at all , what would you do with NEW brass ?

If your getting lines cut in to the powder funnel it's because you did not properly clean the brass in the first place .

You can also dust the mouth of the expander with fine graphite powder or red jeweler's rouge to provide a bit of lubrication. Be aware, however, that both of those are abrasive - a very light dusting will not hurt anything, and won't wear down your expander or case mouths, but don't overdo it.

If you tumble your brass dry, I suggest mixing a couple of teaspoons of red rouge with a bottle of drug store isopropyl alcohol and then spraying onto walnut media. Wait for the alcohol to evaporate and then tumble as usual. This will give your cases a bright polish after tumbling and also provide some lube when mouth expanding.
