Thread: Pressure sign in the single shot

Depends on the sort of single shot action. Falling block like Ruger No1 will be different to say a Blaser K95. Big thing to remember with some you don't have the primary extraction like a bolt action, when you get expansion.
And trust me I found out this the hard way with my No1, in typical windy/dusty nor west conditions in the Mackenzie - dust in the chamber/action don't work well.
