macgrumpy,
i have had no primer issues with this method, so i'm going to have to disagree with you, here.

You also need to be aware of primer seating depth when reloading. Seating the primer too deep below flush can damage the internal components, leading to misfires and inconsistent ignition. Seating the primer too high (above flush) can cause the cylinder to not rotate in revolvers, and can cause problems when the bolt slams home in semi-autos. Seating above flush can also result in misfires.
Unless you are reloading on a progressive machine (each pull of the handle yields a loaded cartridge), the primer seating depth is controlled by feel as the primer is inserted. This is especially true if you are using a handheld priming tool. The primer seating depth is best checked with your finger tip. Sliding the index finger across the bottom of the primed shell case will quickly determine if the primer is above or below flush.
The ideal seating depth is just below flush. As you gain experience in loading, the feel to accomplish this will become familiar. It is best to use your finger to test every primed shell case. If the primer is above flush it can be run through the seating operation again to push it below flush.
That used to be how it was taught. Seat them to the bottom of the pocket. It's always worked for me.I just make sure the primer is seated all the way to the bottom of the pocket
Two things, , ,
1) I did not see if the OP answered the question, "Did they go off once you rechambered the unfired round and pulled the trigger a second time?"
if so, then not seated deep enough and the primers in the picture look a little high to me. What do they look like prior to a firing attempt?
2) Second question would be if he tried to fire these rounds multiple times and they simply do not discharge, then that may indicate a crushed primer. I have a RCBS hand prime tool that will consistently crush primers in the small primer configuration if you squeeze too hard resulting in ruined primers/finished rounds.
Curious if you clean your primer pockets before you seat the primers, i have never had this problem. I would say it could be your striker spring not being strong enough but if you are getting this in 3 different guns it sounds like they are not seated all the way, I would try making 10 rounds clean the primer pockets thoroughly use a primer pocket uniforming tool, I have an RCBS that I put into a cordless drill to use it then a RCBS primer pocket brush that I use afterwards if there is any residual soot in there which I also use in the drill. Im using CCI primers which are notoriously hard primers and have never had that issue.This was struck twice!? Up until recently I had been hand priming all my reloads and seldom, not never, just seldom, had an issue with no fires. I used my 550B priming system for a bunch of 9mm recently and have been having a lot more striker issues. I am wondering if somehow they are getting seated too deep? The original thought was the gun, an M&P, but I have also had issues with my Glock 17 and Browning Hi Power with these reloads. I hope the pics are a clue, I got as closeup as I could.

I can't see it in your picture, but it could be that you are not seating them deep enough.
i take that as a compliment!
Seat them more on a single-stage or something. Gently but firmly. Maybe eyes and earsWow, thank you all that replied. I guess there is always something new to learn and this one kinda came out of left field for me. I have been shooting matches and now have to figure out what to do with the few hundred rounds that apparently are not seated correctly. I would hate to have to pull that many...
