at the risk of repeating myself, I posted the following in an earlier thread: (

I have used
S&B Small Pistol Primers in the past. When they go bang, all is good. When they don't, this may be the reason:
I loaded about three hundred 9mm Luger one day late last autumn because my "cache" was totally depleted. The following day, some family members and I went to the range to, once again, deplete the cache before winter set in
iirc, about 20% of the rounds were p.i.t.a. duds. We tried the duds in two different semis and a wheel gun - solid primer strikes but still no go...
I gathered the duds and went home to dismantle.
It turns out all the duds had no explosive in the primers (pale blue), just bright brass cups and anvils.
I had a look at the remaining seven hundred unused primers from this batch and sure enough, many primers had little or no explosive. I soaked them all (good and bad) in water and tossed them.
I dismantled the remaining un-fired 9mm at some point over the winter and wasn't feeling too happy with Sellier and Bellot by the time I had finished. As I've said before, their quality control must be non-existent!
I guess that I was just unlucky and not as observant as I should have been - one of the few pitfalls of cranking them out on a progressive...

I have never seen this manufacturing error with any other make of primer in my 40+ years of reloading.
Moral of the story: DON"T BUY S&B Primers!!
