I have the same issue...
Dillon XL650.
Those sliding charge bar powder 'Throwers' are expensive and fairly difficult to set up,
And for your cash and aggravation, you get INACCURATE powder loads...
Not to mention they won't throw 'Stick' powder of any kind reliably.
When I'm doing 'Accuracy' loads, I stick with the adapter and my micrometer powder measurer.
It's an extra step for every round, but I don't burn up a ton of super accurate loads anymore.
It took me about two weeks of 'Tuning' my 650 to get it working reasonably well,
Some things just wouldn't work no matter what I tried.
Called Dillon, they say,
"Yup, we've had that issue for a while, you need this widget or spring or what ever, That will be $49.95..."
-----
If you fill up the cases, then the spring detent on the shell plate will 'Pop' your powder out of the case fairly regularly.
By tapering the detent holes on the shell plate (bottom side) and using a weaker spring I found at the local hardware store, It doesn't throw powder all over the place.
----
On small diameter cases (like .223) the spring on the plastic feed thing wouldn't seat the cases under the sizing die.
Dinked with it all over the place, spent several hours trying to tune, clean, lube everything,
Turns out, a long rubber band solved the issue.
$2,000 worth of press, case feeder, caliber changes, tool head stands, ect.
And I can't get them to send me an 'Updated' spring for free...
When I get around to swapping calibers again, or tearing it down for cleaning, I'll hit the hardware store for a spring that works for 49¢ instead of $29 plus shipping...
The rubber band is working for now!

The $250 case feeder wouldn't work correctly out of the box.
The micro switch lever was too long, kept hanging up on the housing and stopping the feed motor.
Disassembled and cut the tail off the micro switch arm,
Works fine now.
The cases hung up on the feeder tube when I finally got the motor to run,
Had to ream a better taper in the tube,
And if the label isn't facing right side up, and facing out,
The cases still hang up occasionally...
-----
Don't even get me started about how the primer feeder leaves the occasional empty slot so your case doesn't get a primer,
Or how there is enough slack someplace for the occasional primer to get turned sideways,
And just TRY to get the unused primers out without taking the entire primer feed unit down to small parts!
-----
They are selling 3 ea. die lock nuts for about $10 last time I looked.
Not enough room on the tool head for the full size nuts that come on the dies...
I know I had seen them somewhere before,
Turns out, they are electrical conduit nuts.
$3.55 for 50 count box at the local electrical supply house.
The list goes on, but I get tired of complaining...
