spilling powder

I bought a 550B over 20 years ago and it has been an excellent machine. About 6 months ago my powder measure began acting up and the folks at Dillon replaced it at no charge. So far so good. Excellent customer service. One problem with this measure is that it has begun to spill powder, particularly stick power like 4350. Before I send it back, I wondered if anyone else had this issue and if there was a fix.

If the powder is spilling when you lift the handle up, then it is most likely that the powder is bridging in the funnel, and being shook loose when the case is withdrawn. Try operating the handle more slowly on the downstroke, so the powder has more time to fall through the funnel. We don't recommend extruded powders for use on calibers smaller than .30" , as the interior of the funnel is small enough to inhibit the flow of extruded powder through it.

I did all that and still got spills. Cases were .30-06 and powder was IMR 4350.

Check to make sure there isn't any crushed powder in the powder die. Take the powder measure off and the powder die out. Check all surfaces for powder dust and corrosion. I had that happen and a quick cleaning fixed everything.
