A combustion chamber (15) featuring an orifice plate (130) which promotes complete, clean, and consistent combustion of the propellant charge used in a powder actuated tool (100). The combustion chamber (15) allows extended operation of a power adjustment means which has improved energy variance, a higher range of power adjustment, and complete clean combustion at any power level. A novel means of power adjustment is presented.
