I have a Sin Arms chambered Savage small shank shilen 30" varmint contour with a SSG muzzle brake. Barrel has less than 300 rounds through it. Has some scratches on the barrel from carrying in the field. With me shooting it was a .75 moa shooter out to 600 yards. With a better shooter I'm sure it will do much better. Decided to go back to a 7mag barrel on this rifle. Will take 350 shipped for it.
