The Weatherby Mark V rifle appears in clause 96 of the proposed schedule, I believe, which deals with high-energy firearms. It's only those Weatherby Mark V rifles that would be prohibited. They are chambered for a calibre that produces energies in excess of 10,000 joules. If the rifle were chambered in a different calibre that did not exceed 10,000 joules, then it would retain its existing classification, which is, for the most part, non-restricted.
