Hi guys, sorry that it took so long but my life got turbulent the last months but the first bolt prototype is almost ready:
As announced: 6.5mm Grendel Bolt,
Face depth of 0.134 +/-
Steel; 42CrMo4 case hardened
not surface plated, yet! It will receive the announced CrN coating in the first calender week in 2014.
I will use a 7,62x39 extractor, it will also be CrN coated.

I am very sorry that it took four months instead of the promised four weeks!
