Case hitting sizing die

I just set up my 650 and am using a very old set of Dillon pistol dies in it. When I cycle the handle, each case hits the side of the die. It's as if the case is bouncing a bit out of the shellplate and isn't quite aligned with the mouth of the sizer die. If I hold each case perfectly aligned, it works ok. I tightened the shellplate and it feels firm. I tried a different toolhead and same thing. Then I tried an RCBS die and it worked smooth as silk. So, I looked at both dies and there is a huge difference in the size of the mouth of the RCBS (way bigger) vs the Dillon. The Dillon dies worked fine in my 550 and there is nothing wrong with them, but the sizing die won't work, very well at least, in the 650. I have several sets of Dillon dies and hate to think I have to buy all new sizing dies. Is it me, the die, or the press? Thanks.

If you look down on the die from above it, where does the interference happen? For the purpose of clock orientation, 12 o'clock is the position where the distance from the shell case to the axis of the large bolt that holds the shell plate in position is minimum.

Or does the interference occur in a haphazard fashion as it would if the shell case were flopping about in the shell plate?

RE: Case hitting sizing die

Hi. Thanks for responding. The situation has changed. I loaded 100 rounds and, almost every time, a case hit the resizer die, even with the wider RCBS die. So, it's not an issue with the Dillon or RCBS dies. I watched and the cases are not being pushed completely into the shellplate. The case insert slide and case insert cam are not pushing the case fully into the shellplate. There must be some sort of adjustment I'm missing.

There is an adjustment. Read the caliber change section of the manual.

See page 38 of the manual, and figures 188-193

I have experienced this and found the problem to be that the ejector wire #13298 is not inserted deeply enough into hole, thereby interfering with the case insert slide, not allowing it to travel all the way forward.

Thanks everyone, I will check the manual and the wire.
