Let me explain it again, that quote describes the gas handling for gas entering the firing pin hole. A ruptured case is going to send gas down the raceway.
How does it stop the gas going down the raceway, or are you just going to avoid the question?
Name a rifle other then a Weatherby Mark V that keeps gas from hitting the shooters face when sending gas down either one of the the raceways. The back of the tikka firing pin assembly fits in the bolt with minimum tolerance, that makes the bolt safer not the plastic shroud. You were implying that the Tikka design was unsafe, I asked you to provide proof.
