The amount of gas in your face is directly related to how much back pressure the silencer creates. Secondarily gas in one’s face can increase or decrease depending on how fast the firearm’s bolt unlocks and extracts a fired cartridge. The velocity at which the bolt unlocks and extracts a fired cartridge increases on average 20 to 30% due to silencer back pressure. It should be noted that gas in the face is not a significant issue with bolt action firearms because the bolt stays lock until the silencer back pressure has dissipated.
