NETim Posted June 17, 2021 Share Posted June 17, 2021 I recently "upgraded" my 650 to use the phenolic ball and lighter spring for the shellplate index. I soon started getting crushed (sideways) primers intermittently. Cleaning everything, shellplate, primer ring etc didn't seem to help. While watching the shellplate index, it didn't always get all the way home. The shellplate notches were not centered on the primer punch at station 2 on occasion. Loading 9mm using WSP. I re-installed the Dillon OEM steel ball and spring and all seems well. Link to comment Share on other sites More sharing options...
ddc Posted June 18, 2021 Share Posted June 18, 2021 I believe that most of these aftermarket "upgrades" are often not necessary and may as you found out introduce problems. Most issues can be solved by proper adjustment and a good cleaning especially if it has been a while. Can a particular problem benefit from an aftermarket solution? Sure, but I'd exhaust the cleaning and adjustment possibilities first. Link to comment Share on other sites More sharing options...

RGA Posted June 20, 2021 Share Posted June 20, 2021 I also agree! I took most upgrades off my 650's again. There are a few usefull ones but most are solutions looking for a problem so to say. (IMHO). Link to comment Share on other sites More sharing options...
Farmer Posted June 26, 2021 Share Posted June 26, 2021 Have you tried the lighter spring with your factory ball? That phenolic ball probably has quite a bit more drag to it. Link to comment Share on other sites More sharing options...

conditionone Posted June 27, 2021 Share Posted June 27, 2021 If you have an index bearing cam block it it most likely not adjusted properly. The adjustment is difficult to get perfect. I had two different brands and after thousands of rounds of frustration I installed the OE block. Perfect adjustment in a minute and I absolutely can not feel the difference of having a roller or not. All the other upgrades are worth it. Roller index bearings are waste of money and more importantly a waste of time. Link to comment Share on other sites More sharing options...

I *thought* I had it adjusted right. Maybe not. Thanks again!!! Link to comment Share on other sites More sharing options...
