Almost any 30 cal can will work for both. Just make sure it's rated for both, though I think it's unlikely a 30 cal rifle can wouldn't be rated for 22-250. A modular design like Rex Silentium's Mod X will give you a bit more flexibility.
There's some, like the Hybrid 46, that'll do almost anything up to .458. you'll definitely lose a little bit of suppression over a smaller bore can, but it'll make a noticable difference on anything you shoot through it. Just make sure you can fully disassemble it for cleaning if you want to use it for rimfire.
