I always use CCI 41 in my Grendel loads. I've seen what a Federal 210M primer can do to a M1 Garand so I know you need a tough primer. The reloaded case with the pierced primer may have been a high primer. My bolt seems to be .002 short of the 2.810 measurement and I am going to get another firing pin.
