No, you don't swap chambers you swap barrels depending on action length and boltface size. ie you buy a 243 you could rebarrel it to a 7-08,308, and the likes but not a 223 or a 325wsm without changing a lot of things, bolt, follower, mag in some instances. But if you have a 77/22 in 22hornet yes you can get it rebarreled to 17 hornet or a K hornet or Calhoon or whatever as long as you stick to that length and boltface size
