Thread: suppressor pressure

My guess has been that the marks are because the air in the barrel and suppressor in front of the bullet can’t escape as quickly as it can when using no suppression or a muzzle break.

Are you running very minimal headspace?

I get the slightest hint of a stamp when using my suppressor as well and this doesn’t show up at all without it fitted or if I’m using older fouling rounds that have more headspace

Possibly I’m loaded up (unsuppresed) very close to the point of a slight stamp or the minimal headspace causes the case head to contact the bolt plunger firmer?
