A turbine blade that may include a tip shroud, the tip shroud having one or more cooling cavities defined therein, an airfoil, the airfoil having at least one coolant passage defined therein, and a plurality of exit apertures defined through an outer wall of at least one of the cooling cavities that, in use, may allow a pressurized coolant to exit at least one of the cooling cavities. The coolant passage may extend through the airfoil such that the coolant passage is in fluid communication with the cooling cavity. And, the plurality of exit apertures may include at least one round exit aperture and at least one non-round exit aperture.
