Gunbroker, armslist, or sketchy dudes from a gas station. Armslist is the best route in my opinion, it saves having to go through an FFL and shipping hassle.
6.5 CM sucks because now I dont want to buy another gun. My $250 16" rifle has low recoil, is quiet with a can while hunting, shoots pretty flat so a dummy like me cant mess it up too bad when hunting up to 300 yards (southeast hunting), and I can still go plinking at 800 yards all the the same...
