I bought 1000 Wolf (same as Tula) Light primer strikes and lots of no fires out of my 226. Never had an issue with Win, CCI etc. I'll have to be really desperate to buy again.
When the "Tula" brand primers first came out the cups were a little thick. It was actually better to use the small rifle primers for positive ignition.
However, the last couple batches that I've used have been 100% so I think they fixed the problem.
Tula and Wolf are pretty much the same in my experience. They load fine. However, when shooting a striker fired pistol I have an occasional failure to fire.
Not a deal breaker. I use them for practice and CCI's for matches. If you have a hammer fired gun, no worries. Bottom line, if you can get em-
get em...
