Well now that I have me's little wife a new (used) Mohawk 600 its time to do something with the one with damaged rifling. The barreled is action about 85-90 %. I have decided that replacing the barrel with a used unknown count barrel would not be cost effective (Bluing, chambering and barrel). So what do you guys think about having it re bored to a 308? I would then have a 308 and wifey a 243. I don't know who is best in or out of state at this and I don't know what twist I would need for a 18.5" barrel. Advice appreciated.
