Samattia Posted August 1, 2021 Share Posted August 1, 2021 The primer pusher on my RL 550C leaves a shallow dents on small pistol federal primers. Usually I will have one or two maximum light strikes while shooting, but today, I was getting so many light strikes that I quit the USPSA match. I usually clean the primer seating cup. After careful inspection, I noticed most primers were concave. Did anyone experience this before? How to fix it? Link to comment Share on other sites More sharing options...
BritinUSA Posted August 1, 2021 Share Posted August 1, 2021 Sounds like an alignment issue, I suggest contacting Dillon and asking for a 550C alignment tool. Link to comment Share on other sites More sharing options...
Sigarmsp226 Posted August 1, 2021 Share Posted August 1, 2021 (edited) Another thing to consider is the shell plate. What has happened to you once happened to me and I caused it (learned after the fact)…..I had recently taken my machine down for a complete cleaning and when I put everything back together I neglected to tighten down my shell plate as tight as I should have…As a result my shell pate was “flexing” enough to cause me the same problem that you are describing…..I went back and tightened my shell plate bolt about another 1/4 turn and it fixed my issue. During that tear down and cleaning I also changed out the indexing ball and spring and because the spring was longer it created more upward push on the plate making me think it was tight enough when actually it was not. Many folks actually snip one or two runs off of their indexing spring so it still functions but allows the indexing ball to sit a little lower under the shell plate…. This may not be the cause of your problem but I thought it worth mentioning because what you are describing - happened to me….Good Luck…Mark Edited August 1, 2021 by Sigarmsp226 Link to comment Share on other sites More sharing options...
GrumpyOne Posted August 1, 2021 Share Posted August 1, 2021 Sometimes debris can get on top of the primer punch and cause small dents in the primer. It sounds to me that you are not seating your primers deep enough. Link to comment Share on other sites More sharing options...

Plus, as hard as I seat my primers, it will dent Winchester and CCI WITHOUT any debris on the plunger. Link to comment Share on other sites More sharing options...
mikedio Posted August 1, 2021 Share Posted August 1, 2021 Good advice from the above posters. You also might want to lube the ram and contact points on the press to facilitate better primer seating. Do not overdue the lube on the ram or you can have a mess. Michael Link to comment Share on other sites More sharing options...
Samattia Posted August 1, 2021 Author Share Posted August 1, 2021 Thank you guys for your input. Here are some pics to better explain the problem. All these rounds mostly won’t function. Link to comment Share on other sites More sharing options...

Samattia Posted August 1, 2021 Author Share Posted August 1, 2021 (edited) The center of the primer is dented inwards. That renders all rounds disfunctional. Edited August 1, 2021 by Samattia typos Link to comment Share on other sites More sharing options...
Samattia Posted August 1, 2021 Author Share Posted August 1, 2021 I believe, this recession in the middle of the primer, damaged its core material. Link to comment Share on other sites More sharing options...

I've crushed them much worse than that and they all went bang. Check your firing pin and make sure there are no burrs on it or the hole in the breech face, slowing down the pin, and check for wear on the firing pin (measure it and compare to a new one).

AHI Posted August 1, 2021 Share Posted August 1, 2021 Just because you have a new gun does not eliminate it as the problem. Try some other ammo. preferably not reloads. now the question I always ask (your primers are fine) wait for it Do you wet clean your brass?

Samattia Contacted Dillon, the shape and dent of the punch impression is not normal. Normally debris between the primer and punch will leave distinct marks, while your picture seems to indicate the punch is actual soft or deformed. The anvil inside the primer has to be able to smash (best word I could think of) correctly to set off the compound. It looks like the punch is forming the primer surface around the anvil point.

I will call them tomorrow. I agree. The face of the primer looks deformed. Something is off with the primer operation. Thx. Link to comment Share on other sites More sharing options...
67isb Posted August 2, 2021 Share Posted August 2, 2021 (edited) I believe issue you're having is due to crimped primer pockets on the S&B brass. Do you have this issue with other 9mm brass? S&B brass is known for having tight primer pockets. It would be a good idea to run them through a swager. Edited August 2, 2021 by 67isb Link to comment Share on other sites More sharing options...

deerslayer Posted August 3, 2021 Share Posted August 3, 2021 Some people air dry them or lay them out under a fan and the primer pockets don’t get dry. An oven or dehydrator should do the trick, though. Link to comment Share on other sites More sharing options...

I've loaded a huge amount of 9mm including S&B and those dents are not from crimped brass and probably not because of a "tighter" primer pocket. The dent looks like there's something not right with the punch. When a primer hangs up and is difficult to press in or is pressed in too far the punch make a flat impression on the primer. Here's a good picture from another thread: https://forums.brianenos.com/topic/172010-can-you-seat-primers-too-deep-without-even-trying/ Edited August 3, 2021 by HesedTech Link to comment Share on other sites More sharing options...
