JDJ CZ-527 Light primer strike

[claydunbar]

Hi folks,

I have 2 JDJ cz-527 .300 Whisper. I am experiencing light primer strike on my reloads using CCI benchrest primers. The load is an awesome subsonic load using 220gr rn hornady bullets, and pattern well inside 1". Additionally I have about 5000 rds loaded so Im now fully comitted. I can take the same cartridges that wont fire In the CX 's and put them in my AR upper and they fire. Has anybody experienced this? Does CZ make heavier firing pin springs? I hope someone can help me because I am very frustrated at this point.

Thanks,
Clay Dunbar
