Calibre does not factor as one of the criteria directly for either the schedules or the evergreening provision. It does have an indirect effect.
I will deal with the schedules first. The firearms named in the schedules are all firearms. Therefore, they must have a calibre. That means that those particular calibres are affected to the extent that the firearms that use them are listed in the schedule.
In the case of the evergreening provision, it's limited to centre-fire calibres. Any firearm that's chambered for a rimfire calibre would not be affected by the evergreening provision.
