I have no direct experience with 6.5 CM, but from reports it's tough on barrels, some reporting as low as 1/3 the barrel life of a .308. As a new LR shooter, you'll need to put a fair number of rounds down range to develop your shooting skills. Something to keep in mind, at the very least you'll want either a Savage or 783 to make barrel replacement easier and cheaper. As far as glass goes, Sightron makes excellent stuff at fair prices.
