Sorry... as you can tell I have still not learned to go back and proof read my postWhats a "very" cup??? They are thick or "hard"
Yes they are fine in a AR. Any primer is (well maybe not Federal match) but look at all the load data regular SRP have been used for many years before they tried to sell us Military #41 primers.
Maybe if you load Service loads, but a slam fire is not likely in a semi auto, It's not a full auto situation!
S&B SPP are harder than CCI #500 SPP and Federal 100 SPP judging from test data I saw that measured primer dents. I've read it elsewhere and have personally experienced light strikes with S&B SPP in a revolver which had fired 1000+ rounds of various brands of ammo without one light strike. I could easily see the primer dents weren't as deep. I went to a heavier main spring and no more problems.I understand these primers have very cups. Are they ok to use in the AR15.

as I should..... I have read that the cups are very soft and ARs has the floating firing pin.....
And get this over in the reloading where it belongs.........whew 🤪
Nailed it. The gauge of the metal used in the primers denote hard or soft as in strike ignition.The opposite. S&B are "hard" Actually there are no hard or soft primers. It is really how THICK the metal of the cup is. So thick is "Hard"
I have some "tuned" revolvers that will not ignite a SB primer, sometimes it takes a double strike (yes they are seated properly) Thats why super light hammer guns folks use Federal as those are "soft" ie, thin.
