I have had excellent results with CCI.
When primers are unobtainium, I bought what was available - S&B. These suck! I bought a brick of SPP's and they are way too soft or something. They go Bang - but Almost all of them deform while being seated.
These are plinking rounds, using mixed brass head stamps. that I reloaded yesterday.
I have never had this problem with my reloading standard - CCI's.
I added a picture of some 10mm I recently reloaded with CCI primers for comparison.
