Ok, so I am rather new to the 6.8mm round but have had great experiences with it. I am also new to the bolt-action realm as most of my time has been with the AR. My question is if the 6.8mm round is a .270 caliber round why couldn't you put a .270 barrel on a .223 action and widen out the bolt face? With the way Savage receivers and barrels are would it be at all feasable? Or is custom barrel still the best way to go. Thanks for any help for a bolt noob.
