First of all, I wouldn't characterize the PC carbine as a hunting rifle. The PC, to my recollection, stands for “police carbine”. It's a small semi-automatic carbine that has a standard magazine size of I believe just under 20 cartridges—17, perhaps. I'd have to look it up to be sure.
As such, it would meet the evergreening definition in that it is semi-automatic, it fires a centrefire cartridge, it has a detachable magazine and the capacity of that magazine exceeds five shots. That firearm would be captured by that definition if it were to come into force.
