Dillon Powder Funnel/ Case Belling Sticking Problem

[BE Mike]

I had been having the Dillon Case Belling/Powder Funnel. Upon close inspection the problem seemed to be streaks of brass left behind after tens of thousands of reloads. I removed the powder measure and set it aside on a die stand with dies. I then removed the powder funnel. I found out that the Sinclair Case Deburring Power Adapter (https://www.sinclairintl.com/reload...se-mouth-deburring-tool-holder-prod34054.aspx) that I use in my bench drill press, accepted the Dillon Case Belling/ Powder Funnel. After tightening the set screw I turned on the drill press and used 0000 steel wool to clean the Dillon Funnel. When I was satisfied that it was clean, I then used some liquid Flitz on a clean cloth to polish the Dillon Funnel. Afterwards I used a clean cloth to remove the Flitz. Quick and easy! Brass now doesn't stick to the funnel.

That is amazing. What made you think the Dillon belling/powder funnel would fit in the Sinclair adapter to begin with? Just WOW!

I had the Sinclair power adapter already chucked in my table drill press. I looked at the powder funnel and asked myself, "I wonder if this will fit?" That's the way my mind works. I don't look at numbers when I pick out a wrench. I look at the nut or allen screw and match them up from sight. That's why I would never be a good mechanic or carpenter and envy those who are.

I had the roughest time with sticking brass on the dillon funnels after pin tumbling brass.
Read of others with same issue and tried their suggestions.
I now tumble without pins and after initial tumble with dish soap & small amount of lemi-shine crystals, i will rinse and final tumble with armour-all car wash(table spoon to 1gal water). Then drain water (no rinsing) and dry. This will leave a very thin coat of silicone. Seems to help with the brass sticking to a polished funnel. Also keeps the brass from tarnishing over time.

New brass (virgin) tends to stick inside the sizing die and funnel. I haven't loaded any in a long time, but I always tumbled the new brass with ground walnut shells and liquid Flitz. It seemed to help a lot. Like you say, a well cleaned and polished Dillon powder funnel is also necessary.

Throwing them in a tumbler with walnut media and Flitz works too.
