ronn Posted December 11, 2022 Share Posted December 11, 2022 (edited) After many rounds of 45 on my 650 with my RCBS sizer die it stared crunching the top of the casess, see picture. probally 1 every 7-10 rounds. I have cleaned, adjusted and fiddled. I figured it’s probally something I am over looking. Any suggestions before I chuck the die and buy a new one.

Don_B Posted December 11, 2022 Share Posted December 11, 2022 The cases are not lined up with the die. That is not the die's fault. Check and see if there is media or some other crud in the shell holder that is preventing the cases from going in straight. Link to comment Share on other sites More sharing options...
Vizorn Posted December 12, 2022 Share Posted December 12, 2022 Might also check to ensure the Case Insert Slide Spring (Dillon part #13937) isn’t broken. Link to comment Share on other sites More sharing options...
rishii Posted December 12, 2022 Share Posted December 12, 2022 I had the same problem with 9 mm checked all the usual suspect's with no joy than I found the spring under the ball detent was dead which caused the shell plate not to index properly Link to comment Share on other sites More sharing options...

Jim Watson Posted December 12, 2022 Share Posted December 12, 2022 MY old .45 RCBS sizing die is dead flat across the bottom with no radius and very little taper into the carbide insert. The tiniest of misalignment would keep a case from entering it on the sloppy Dillon shell plate. You will likely have to keep a fingertip on each case and guide it into the die. I got tired of that and went to preprocessing cases in single stage. If I were going to load a lot on the 550 I would get a Dillon or Lee sizing die, but it has only been for about a thousand .45 Small Primer cases in the usual 9mm press and I am nearly done with those.

HOGRIDER Posted December 13, 2022 Share Posted December 13, 2022 Definitely check your case slide for proper orientation of the case in the shellplate............ Link to comment Share on other sites More sharing options...
anachronism Posted December 31, 2022 Share Posted December 31, 2022 You may need to check your platform alignment: To do so, you'll need this tool: https://www.dillonprecision.com/13713 And/or it may be necessary to adjust your indexer cam position: Link to comment Share on other sites More sharing options...
