The firearms that are in that list are based on the same criteria as the May 2020 list, except that the conditions of modern manufacture or modern design and large quantities present in Canada have been removed. Those criteria from May 2020 do not draw a distinction between firearms that are chambered for rimfire calibres versus centrefire calibres. It's only happenstance that the nine families prohibited in May 2020 were all centrefire.
