Anyone else use one action and swap between barrels? I'm not talking about a plain out conversion. I have a .308 I built off a varmint action and I'd like to try a .243 AI as well. I can get a .243AI varmint barrel for around $340. I don't want to give up the .308 for good just try the 243 for varmint shooting and swap back when I'd like to shoot the 308. Anyone?
