Q: Will this extractor work with 12.7x42 beowulf.
A: If the 12.4x42 uses a bolt face of .136" it should work.
Q: I’ve read that this .135 recess extractor is compatible and will function in a 7.62x39 bolt. To your knowledge, is this correct?
A: No you will experience extraction issues. If you have a 6.5 bolt assembly stick with a 6.5 Grendel Extractor and if you have a 7.62x39 bolt assembly stick with a 7.62x39 Extractor. The ten thousands difference in bolt face face does make a difference.
Q: Will your Grendel type II extractor also work in a type I bolt ?
A: No as a Type one bolt has a .125" bolt face and a Type II has a .136" bolt face. You would need a 7.62x39 extractor which is considered a type I bolt with a .125" bolt face.

Q: Is this for the "type 2" bolt with .135 to .136 bolt face depth? I recently bought a bolt that had the wrong extractor installed and it will not extract shells at all.

Q: Is the .223-.5.56 extractor the same as 6.5 Grendel extractor?
