XL650 Odd Brass deformation - Sizing Die

[Buckshot Bear]

What could be the cause of this odd brass deformation that is happening occasionally out of the resizing die loading .38's on my XL650?

Probably the decaping rod is hitting the edge  due to some slight misalignment.

Since the decapping rod (and pin) are supposed to run down the exact center of the case, if the rod were that far off center, then the pin would miss the primer flash hole by quite a bit. Still... probably worth checking.

 

If the 650 shell plate is anything like the 550 shell plate, my guess would be that the case is not fully seated in the cutout.

I had that issue with my 650 and .38’s. The shell wasn’t completely seated in the shell plate due to the handle either stopping half motion or not all the way back up. When handle pulled back down the shell would hit the side of the die and depending how much force was behind handle would dent a little or a lot. 
 

not sure what yours is from but I found it was something I was doing with my motions that caused mine.

When I first setup my 750 i tried several types of primers and with one of the European brands they seated fairly hard. This had the effect that sometimes the handle wasn’t fully forward and the shell was not completely in place entering the sizing die. The end result looked just like yours. Changing primers to federal made for easier seating and that change in technique made the problem go away. Mine was so infrequent that I didn’t make any adjustments. Though I am not sure what adjustments could be made.

On a 550 the spring needs to be adjusted properly for the decapper/ sizer die to function properly. The one that holds the case in the shellplate. We don't have the problem with the larger calibers but do once in a while with the 38 sp and more often with 32s.

I had that problem years ago with my Hornady LNL. The shell plate wasn't indexing quite far enough on the upstroke and hitting the decapping pin. Adjusted the pawl about 1/8 of a turn and haven't had the problem since.

Remove ALL up/down play in the shell plate. 

Check the position of the shell locator spring on the first station.

Make sure you complete the stroke that seats the new primer!  That is what pushes the next case fully into the shell plate.  There is some “give” in that part of the stroke and you have to use up that give.

I had this exact problem on my 650 with .38's. It disappeared when I tightened up the shell plate. The casing was misaligning at the powder/belling station. It wasnt exactly loose but there was some up and down play and it only damaged cases randomly.

My case was misaligned at powder station . Why?

Because I failed to change pins from 45 acp back to 38

This deformation is caused by the case mouth not being lined up with the powder funnel. On the 650, there is a spring-loaded finger at station 2. It prevents inertia from flinging the case out of the shellplate as the shellplate turns. You can adjust how close this finger is to the case via a set screw that is horizontally mounted the the base of the primer feed. This metal finger should almost touch the side of the case. A gap  of .002-.004" is preferred.

Next, push down on the edge of the shellplate at station 4. If it feels springy, then the shellplate bolt needs to be a bit tighter.

MM, thanks for chiming in on these issues with such a fine product. Dillon should be proud! You are a fine representative!

That happened to me and was so damn irritating.  It happened at the powder  drop station… it was just a wee bit off. 🤦🏼‍♀️Captain Baylor told me of a little screw that I didn’t even know was there. I adjusted it and it was pretty much fixed. It started again and I removed the shell plate and primer assembly and cleaned it really well and now it’s rare. 
 

I have found that when weird stuff happens, go back to the basics/beginning. It mostly helps. 😉😂🥰

The little tiny hole on the right is where the screw is. 
 

Hugs!
