May not be the primers, maybe your reloads ?

Your brass too short for your chamber ?

Ok thanks,
That never occurred to me, so some over-trimmed brass? Hammer striking and case having movement=not enough force to detonate.
This might actually make sense as think it was just doing it in my 5.56 Daniel defense but don't think such a problem in Rock River 223 Wylde chamber.

Using trim length from ADI book, what length would you suggest?

Yes, always loved Federal stuff as always Mr reliable
