I need some advice on the filling presure for the s200. What is the optimum maximum and minimum pressures for this rifle? How does fillig presure effect your zero?
Max fill is: 190 bar (2750 psi).
Every rifle is pretty much on it's own in this department, you would best find out yourself by shooting a string over a chronograph, then check the POI difference at various shot numbers. (ie shot 1, shot 10, shot 20 etc...)
I know my S400 likes 175 - 110 bar. And the max fill is 190 although I don't normally fill to that level.
