nothing cheap about rebarreling. 450$ . and be cause of the bolt face you cant' go to .223 WITHOUT a lot more expense. it is easier to sell what you have and buy a .223. i have 6 243's. they are awesome. i have one with a hart barrel shot a coyote tuesday. last week at the range the 5 shot group was the same size hole AS ONE of the my 30-06 rounds. they are deadly. rebarreling to save money on ammo?? reloading could help.
