Well that is unfortunate news that the .264 WM is obsolete. I have a new one in the gun room and a flat rate box full of once fired brass I was hoping to play with this spring.
First of all, why waste your time and effort on an obsolete round.
Secondly, all your components won't do you any good since you can't get bullets.
Thirdly, so I'll PM you my address and you can send that obsolete rifle/cartridge and components to me. I'll take it off your hands and leave you more room in your safe/storage.
That's the least a fellow loony can do for another!
