Primers turning and crushing

Finding more primers getting crushed or entering sideways into the case. Everything seems to be fine, but seeing more of this with good brass like win and fc. Insight is appreciated.

RE: Primers turning and crushing

"Case prep is everything." One of those quote that gets tossed around. But some truth there. I recently ran into some Winchester pistol brass that had what appeared to be crimped primers. Could it be that your brass has some cases that had crimped primers? I have the L.E. Wilson tools and ream anything that appears to need it. Makes the primer pockets uniform and adds a nice radiused edge.

You may try cleaning the primer system. Especially under the Rotary Primer Disk. Check the brass tip on the Primer Magazine. It may have been buggered up if over-tightened.

Check the plastic tips on the Primer Pickup Tubes. If they get worn they can flip the primers. Of course I would think that would cause a jam and you would notice.

I just looked over the Troubleshooting Section of the manual. Page 42. A lot of possibles.

Thanks, already tore down and checked the primer assembly. I'll pull out the manual and check the page.

You did not say if you were encountering this problem with pistol, rifle, small, or large primers? I've had large pistol primers get turned sideways and not knowing them pushed them into the primer pocket.

This problem happens on the Super 1050 too.
The culprit: Federal/FC/American Eagle cases.
The decapping rod in the Dillon sizing and decapping die fails to fully push out the primer in almost every FC headstamp case.
The partially pushed out primer dangles and causes the following:
1) The shell plate gets jammed and cannot advance to index at the next station
2) If the shell plate does advance, at the priming station, the new primer is crushed against the still dangling spent primer
OR, the new primer pushes aside the dangling spent primer but is turned sideways in the process and crushed in sideways.
3) on the 1050, the swaging station crushes the dangling spent primer back into the pocket. Both the primer and the pocket are ruined; the whole shell is destroyed/rendered useless.
Then, if the not so mangled FC case and the shell plate can advance to and index at the Priming station, the new primer is crushed against the flattened “swaged” spent primer

RE: Primers turning and crushing

I had issues with a lee progressive and with the xl650. The way I resolved it was to deprime by hand then tumble the cases. Then I got a rcbs automatic priming tool and I prime by hand. With the rcbs tool I took the plastic end off the tool so I could use the Frankfort arsenal vibrating primer tool to put primers in the tube. Very fast. And for the trouble it saves its worth it I think. I crank rounds out pretty fast only thing now is once in a blue moon a case will feed in upside down not a big deal. I do 4 rounds of 9mm In 4 minutes on the xl650. The other thing I have is a girlfriend that likes to deprime and prime for me when we are hanging out. :)

Also I removed the deprime pin from resizing die

Make sure your bunch that the press is mounted on is very secure and eliminate as much shake and vibration as possible.
Use even strokes of the press and avoid hard strokes as this will shake the press.

RE: Primers turning and crushing

It would depend on how frequently a primer gets cocked whether it would be reasonable to do this. Load rounds and before each stroke, remove the case that is in the priming position to determine if the primer is sitting properly on its ram. If it is not , that eliminates cocking during the seating operation. If it is not sitting properly, then the problem is in the primer feeding system. Also check to see if the primer is positioned correctly relative to the cartridge case. This is the brute force method of finding your problem but it will work.
