I have a Shilen, #5 contour, 28" long, 10 twist, chrome-moly barrel. It has been chambered for 280AI and threaded for Rem. 700 action. It has been shot about 20 times, enough to break the barrel in, never did work out a load for it. I changed my mind about the caliber and desided to build a 6.5-06 AI. This Shilen should make somebody a good shooter. I have about 400.00 invested, with chambering, threading and crowning. I will take 250.00 for it, shipped.
