I always thought .223 or "military" SR primers had harder cups to prevent slam fires than regular SR primers.
Regardless, I make sure I seat them slightly below flush (.004") for my AR.

Made sorta specifically for AR15's. The floating firing pin can actually dimple a SRP just from being chambered. A slamfire could theoretically happen in an AR15 even with the primer seated below flush. I wouldn't use them for any other .223 unless for a specific reason. Even 99.5% of AR15's can use normal SRP with no problem.

Never had a slamfire in my AR.
I just wanted to save $12.
(Tula 223 primers vs CCI 400)
I was hoping for someone who had recently redone their workup.
What was the result?
