Above quoted regulations are those in force prior to the new legislation. High powered rifle is a term applied to centerfires in the .270/.30-06 class, and yes previously only rifles chambered for pistol cartridges (low powered as you choose to call them) were legal. I think you knew this before posting though.
As per the posted regulations, rifles other than those in "pistol cartridges" are legal as well. I think you knew this before posting though...
