Unless you have a fast twist 22-250 I wouldn't bother with the big cases. You gain very little useful ballistic advantage shooting the light bullets in the big cases.
If you just want to have some fun with the remaining barrel life, than by all means try the 22-243, 22-6mm, 22-284 or similar; you'll have blast!
Ok so I'm ready for the replys. I had some 284Win. brass and went ahead with form and F.L. dies and necked them down to 22-284. After turning the necks to .014" then annealing I again sized the necks for uniformity, starting loads anyone and other than Quick Load data real range results would be great!
I picked up the dies and chamber reamer at close out prices....I couldn't resist.
