I scraped a 6.5X47 build I had this barrel for. It's a 1-8 twist to finish at 20 to 22". Would be great for a 6.5 creedmore, 260 or 6.5X47. The muzzle measure right at .75 @ 22". $450 shipped CONUS I have more than this in the barrel and am not looking for offers. If it don't sell I or one of my buddies will use it.
