650 PRIMING


Recommended Posts

I see that the 650 priming system is a rotary disc unlike the 550 sliding bar. My question is what do you do to get primers in the ready position before the cases get there?

I know it probably sounds trivial but there is nothing about it in dillons manual. It just says load cases and primers and pull handle.

You need to index handle a few times to get the primers fully loaded in the disk. You will also need to run a few strokes of the handle when you are finished to clear the cases from the press this will result in a few primers being ejected into the primer tray. I usually just hand remove them as I index the press, the primers are still good and I just put them back in the primer loading tube.

The way my 650 works is you have your first primer over the punch after 8 pulls so what I do is pull the handle 6 times and then turn on the case feeder. Once there are a few cases in the tube you pull 2 more times and you have the first case primed. If you want to clear the wheel you have 11 primers left after the low primer signal fires.

Later,

It takes 8 advances of the disk to get a primer on the priming punch. I take off the activating block off the frame when I set the powder measure so I don't advance the primers and start dumping them down the chute.

Likewise, when I want to cycle the press without feeding primers as when I am adjusting the powder charge, I remove the cam that operates the primer feed. The holes in the left side of the strong mount make a good place to store the two most used T-handle allen wrenches for this task.

cycling the handle 6 times before turning on the case feeder worked great, the only think si I have gotten way to many sideways crushed primers. I am working on getting this corrected though.

As above after two strokes of the handle I have a deprimed case at station 2, I remove it manually index until a primer is above the seating mandrel and reinsert case and prime.

For the sideways primer, don’t forget there is an adjustment screw for the station 2 locator tab, the book calls for .010 between the tab and case. You might run a few with tolerances a little tighter and/or looser to see how the machine responds. With a little adjustment even S&B cases are no problem.
