Greetings Larskramer,
You seem to have most of the modern stuff covered so I suggest a .280 Ross. This will keep you busy finding cases, projectiles etc. plus developing loads for quite some time. It won't do anything half a dozen modern cartridges (at least) can do but when you uncase it on the range you can be pretty sure it will be the only one there. Look it up and give it some thought.
Regards Grandpamac.
