Need help with Dillon 650/9mm issue.

[melliw]

I have been having a problem with reloading 9mm on my Dillon 650 and am looking for some advice.

The problem that I have been having is that cases are getting hung up on the first station when they make contact with the lip of the decapping/resizing die.

I have to reach in and push on the top of the case slightly tilting it inward thus allowing it to enter the die. This happens with about 70 percent of the cases. I checked to see if it was a particular type of brass and found that there was no pattern. The cam has been adjusted forward to its maximum position to ensure that the cases are being seated into the shell plate. Speaking of shell plate, I have taken it off and cleaned out the groves that the brass fits into.

I also load .45 and .223 and have not had this problem with those loads. Dillon focused on the shell plate but it did not resolve the issue. Has anyone had a similar problem? Thanks for taking the time to read.

Sound like the shell plate is too loose.

I agree plated might be loose but if its not......

When it hangs up have you tried moving the handle forward again. The forward motion should push the case all the way into the plate.

Die issue?

Gremlins?

Bingo snug up the shell plate.

I had a small tiny little grain of something in the round part of the shell plate once. So every time a case was inserted into that spot on the shell plate it wouldn't go in 100% and I'd end up smashing the case because it wasn't centered with the die. But that doesn't sound like your problem.

I replaced the shell plate with a new one and ensured that it was tight. In addition, I replaced the toolhead but the problem still exists.

Upon further inspection with a piece of brass in the shell plate and the brass touching the bottom of the die, I can see that they are not aligned. the brass touches the lip of the die and is about 1 or 2 mm off from being able to enter die on its own. the slight push is needed to have the upper edge of the brass tilt and enter the die.

Guess I will try a new die.

Thanks to those who offered a solution.

Is the tool head securely locked in place? Any burrs on it that might allow it to be slightly out of place?

If you rotate your die 180 degrees, does that eliminate the problem or move the point where the casing impacts the die? If it does, your die is not centered.

Is your sizing die locked in place or loose. If locked down, did you lock it down when you had a case run up into the sizer? With it not locked down, you'll notice there is a slight amount of looseness in the die.

Hope that helps you find your problem.

Thank you Dr. D. You have given me more to work with. I cleaned out the slots where the tool head slides into the press and even changed the tool head. Neither helped.

Moving the die did not make a difference. The die is locked down tight but what I did not do was to lock it down with a case inside while attached to the shell plate. The shells have a very small amount of play while in the shell plate especially in the first position. The amount of movement on the top of the shell is about 1 to 2 mm but it is enough for the case to get hung up as I try to move it into the die. I like your suggestion and am going to try it now. Thank you.

Just curious, what brand of dies are you using?

You're obviously very good with spatial relationships. That's a pretty rare skill from my experience...it seems progressive presses are one of the hardest tools to understand...

Thank you although I'm not sure the praise is deserved. I trouble shoot for a living.

Let's see if my suggestion works.

I did too. Do that for a while and you develop your pattern of what to look at...

readjust the case pusher thing, its not supaosed to "over" push the case in just get it to seat.
try that.

Did you modify the spring the pushes on the detent bearing. could be weak spring on the detent ball. Also watch that your case is getting push all the way forward when you push the handle
