Dillon BL500 Powder die weird problem needs help

[laohuang]

while reloading 9mm with Dillon BL500 encountered the weird problem as picture show below (occurs about every 10 brasses)
It is the 3rd stage powder die deformed the brasses
Who can offer some ideas and suggestions to help me to resolve the problem?
Your kindness and support are very much appreciated

Looks like the brass is out of alignment. I have the SDB so not sure about BL500 details. Does it have the little positioning pins? Is the pin in place? Did you add aftermarket plastic tabs on the pins?

Dillon CS would probably have the best advice.

Make sure you are using the right size pins.

I don't have a Dillon BL550 but, I think the powder funnel is for station 2, not station 3. Powder funnel at station 2 and bullet seater at station 3.
From Dillon's website:



1. Place an empty cartridge case into the BL550’s shellplate at Station One. Lower the operating handle. The BL550 will deprime and resize the case. While the platform is in the “up” position, set a primer into the primer-seating arm. Raise the operating handle, and push it forward to seat the primer into the case.

2. Advance the index sprocket with your thumb and lower the operating handle. At Station Two, pour your powder charge into the case. Raise the operating handle and advance the index sprocket with your thumb.

3. At Station Three, place a bullet on the powder-charged cartridge case and lower the operating handle. This will seat the bullet into the case. (NOTE: with some manufacturers die sets, it may crimp the bullet in place as well.) Raise the operating handle and advance the index sprocket with your thumb.

4. At Station Four you may use a separate crimp die (most Dillon die sets incorporate a separate crimp die to facilitate easier die adjustment) or simply advance the shellplate with your thumb and remove the loaded cartridge from the shellplate at Station One.

What next? Repeat steps “1” through “4.” Sound easy? You bet it is!

Is your press securely fastened to a solid bench? If the pins are correct, maybe the brass is 'rattling around in the shell plate carousel and when on the way into the die, they are misaligned due to shaking?
Are you flaring the top/mouth of the brass before inserting a bullet?
