Not sure who you're addressing Elmar, but I'll reply because I'm bored.
All I can say for sure is that these primers were seated properly, with significant pressure and crushed into the bottom of the primer pocket. They were fired through two different completely stock Glock 22 second generation pistols. Both Glocks had failures to ignite on roughly 12% of the rounds fed through them. Out of the 12% that failed, half would not fire on a second strike.
The same batch of handloads were fired through my M&P, which just recently received a new OEM striker assembly, and they all worked fine.
Aside from that, both the Glock 22 pistols have previously fired CCI and Remington primers (2k-3k each) without any failures.
Until we tried the handloads in MY G22, I was thinking my dad's G22 needed a striker spring replacement. And then the rounds failed in mine the same way.
So, all things being the same, I blame the primer. With the facts listed above, you may draw a different conclusion.
Like I mentioned earlier, lots of people shoot these primers without an issue. But there have been numerous documents issues that some have had, including myself. Y...M...M...V.
