Hornady, Hawk and Buffalo Arms have bullets, Sellior & Bellot imports loaded ammo. You could easily build a bolt gun on a Savage 340, Rem 788, Win 54 or any bolt action that originally came in 30-30.
It would make a lot more sense to do it in 219 Zipper just for the .224 bullets as there are plenty heavy bullets in .224 now.
I've been looking at Euro combo guns in 22 Highpower/5.6x52R so I've spent some time looking at the cartridge.
