Twisted Small Primers
Quote from CrystalRed on August 12, 2024, 11:19 pmHas anyone seen this before?
Seems that my SDB plate sometimes hitches on station 2 catching the feeder surround on the plate and this causes either the primer to jump out of the tool and onto the floor or for the primer to be inserted crookedly. I feel nothing in the handle to indicate a problem is occurring.
I plan to deconstruct these rounds. Is it safe to use Station 1 to eject these twisted primer?

Measure from the underside of the primer slide to the top of the primer cup. It should be 1.410" +/- .003" If necessary, use a c clamp or a vise to hold the cup & punch down while to tighten the set screw.
Spray some WD-40 into the open primer cups, let set overnight. Then you can gently deprime these cases.

Just a quick follow-on question.
The primer slide and primer feed adjustments are part of station 2. I shall check these now and adjust if necessary.
How is this related to de-priming in station 1?

Quote from The Human Manual on August 14, 2024, 3:38 pmYour problem is the primer cup coming up through the shellplate. This has nothing to do with the depriming process.
In order to more safely deprime the sideways primers, you need to desensitize the primers using WD-40 first. Then, after you use a kinetic bullet puller to remove the bullet and powder, you can gently run these cases back through station 1 to push the primer out of the pocket.

The rounds have all be deconstructed now. Though I haven’t reloaded again yet, the machines seems to be operating way more smoothly than before.

When you lift the handle up and push it forward, pick the primer up. Cycle 10-15 primers through the loader this way. Do any come up sideways or upside down? If no, then you should be good to go. Be sure all the brass locator pins are installed.

Quote from CrystalRed on August 15, 2024, 3:58 pmThe caliper conversion is complete and the machine is running swimmingly once again having made 185 rounds yesterday morning.
Thank you for all the assistance!
Out of the box, my SDB was setup for .45 auto and worked very well.
I bought the 9mm conversion kit which took > 1 year to arrive. Once it did arrive I didn’t know about the Quick Change Kit and I proceeded to try to adjust all the dies from .45 settings to 9mm settings.
In the process of doing all that I also changed the primer magazine and the primer slide only to have this hitching problem occur with the primer cup on the primer slide against the shell plate. Measuring and adjusting the set screw on the primer slide and primer cup, as well as liberating the primer slide wheel, got things back into working order. Out of the 185 rounds only 2 didn’t pass the plunk test with the case gage. I believe these were with the brass I used a bit when dialing in the flare, seat and crimp settings. I adjusted the crimp once more and they now pass plunk. None of the bullets spin by hand in the manufactured rounds. And, the crimp measurements were w/in the 0.001-0.003” suggested tolerance; I measured quite a bit of the 185, but not all.

It takes time but is well worth it.
