I have been using my Dillon 550b for a couple of years for 9mm and 223 without any problems. Today, I noticed that every 5th round my Dillon went bonkers and threw enough powder to overflow the case (Using Varget for 223). No problems earlier this morning. I am in the process of emptying and cleaning everything, but I was curious if anyone has had this problem - and in particular, any fixes! Thanks for any help>

varget will bridge in that powder thrower unless you are really slow. Like one second up, one second down. And realize that every overflow has a corresponding underflow.
Choid - thanks for the info!
This is what is happening. I've had good success with short extruded powders in a Dillon measure but Varget has been too finicky.
8208 xbr is about perfect for extruded in a Dillon. I also use 5744, which may be slightly bigger, but not much. It's a great powder thrower for ball powder.
8208XBR is a terrible powder
I sung the praises of it years ago but now that I can't find it on the shelf, it's the worst powder for any use
One thing I did to correct Varget bridging is increase the taper of the stock "A" powder funnel with a 1/2 - 1/8 reamer. The T handle presses out and the cutter fits in a 1/2" drill motor making the process very easy. It not a 1000 round an hour solution, that is, it doesnt speed things up, but with a reasonable tempo, I stopped getting even occasional varget bridging with my 25 grain load.
