Just bought a slightly used 357 Blackhawk Convertible. Took it to the range and tried out four loads: 9mm (w/the convertible cylinder), UMC 38spl, Win White box 38spl +p, and UMC 357mag.
All worked well, except that 20% of the casings in the UMC 38spl load had blackened primer impact points.
Couple of questions: Is this what a pierced primer looks like? Is it dangerous? If so, what could be causing it and how do I fix it?
Thanks.
