I was good through 3k of them. Only had maybe one dud, and wrote it off as a freak incident. Then I had about 10 duds with my last 1k batch of Tula SPP. And I've had 1 dud through 1-2k of the Wolf 223 primers. These were not seating issues. Some may have been firing pin strength issues, as many of those 10 duds happened in the same gun - a stock GP100. But at least 3 of them happened in Glocks with very clean firing pin channels.
I've used 2k of the Wolf LPP, and no problems. I will probably keep buying those.
I've read of people having the occasional bad batch of domestic primers. But until I've experienced that, I'm sticking with CCI and Winchester; cuz my failure rate with them has been zero. And that includes when I first started loading and my seating consistency was all over the place. One bad primer is a waste of not only one round/primer, but also your confidence in the rest of the batch. There's nothing worse than socking away hundreds of rounds of ammo before finding out your batch of primers is unreliable.
I realize this is completely anecdotal; lots of people swear by Tula's reliability, but I can't help it that I no longer trust them. If I'd had a bad experience with Win or CCI, and never had a misfire with Tula, I'd be buying Tula.
