Re: Switch barrel rifle question, long action .223 Savage?
For openers, you can change the bolt face to a .384" diameter which will accept the .223. The BVSS is a single shot, so feeding should not be an issue, but I am not a gunsmith and some one else has to answer that. The beauty of a Savage is that you can alternate these components to suit whatever caliber you want.
When changing Savage (or any other) barrel, be sure to use go and no go guages to be absolutely certain your headspace is spot on.
