13. A setting tool for actuating a tool in a wellbore, the setting tool comprising:
an outer sleeve having a proximal end portion, and a distal end portion, the outer sleeve defining a longitudinally-extending central bore;
an inner piston extending through the central bore and having a proximal end portion, and a distal end portion, the inner piston defining a piston cavity having a power charge received therein; and
a mandrel extending distally from the distal end portion of the inner piston and protruding distally beyond the distal end portion of the outer sleeve, wherein the distal end portion of the inner piston defines an elongate bore axially therethrough, the elongate bore having a proximal end and a distal end, the proximal end of the elongate bore being positioned adjacent the piston cavity, the elongate bore being in fluid communication with the piston cavity and extending from the proximal end of the elongate bore to the distal end of the elongate bore parallel to a longitudinal axis of the inner piston.
