I know this is a few months old, but I was recently in a similar situation looking for a .223 bolt gun so thought I would share my experience:
Purchased a Savage Lightweight Hunter in .223 and was plagued by feeding issues as Savage uses a .308 sized action which is simply too long and allows the cartridge to exit the magazine before the bullet enters the chamber. It is a fundamental design flaw that cannot be solved, so I rebarreled in .308 (and have still been having issues due to Savage's shit magazines, but that's another story). Went back to the drawing board and purchased a CZ 527 Carbine and couldn't be happier.
Unfortunately the 527 has been discontinued for the CZ 600, however I would caution against that as they are currently under a recall and as far as I can tell the issues have not been ironed out. If you are able to find a NOS or used 527, one other thing to note is that the is that it was produced both in 1-12 and 1-9 twist barrels, so if you go that route make sure to get the faster twist.
