Well i imagine you can re-barrel it in any short action cartridge with that boltface (like 260 7-08 308 etc)...but 22-250 is a great cartridge in the right rifle...
I know of a later vintage mod 70 in 257 roberts, but he wants $800 for it...trouble is, it doesnt shoot, seperates cases & so desperately needs a new barrel...that makes for an expensive rifle.
Not sure why the swift is of interest if you're sick of the 250--they seem pretty similar.
If you like shootin the 788/222
dont buy a 204...
Or...
If you want the barrel to last for ever on the 788, DO buy a 204...
But dont get a 204 before March...you dont want to be found out in the paddock with a pile of fur at your feet when you're supposed to be at the alter...
The man who knows everything, doesnt really know everything...he's just stopped learning...
