I've got a 550FS in 6.5x55 and love it. It's very accurate, although not a consistant one hole shooter like my 452 Lux. But then finding a factory center fire rifle that is, is a rare thing. Point of impact does change, but just a bit. As a hunting rifle, this is not a problem since you wouldn't be shooting a dozen times at the same critter. But if you're shooting targets, just let it cool down a bit after you empty your magazine. Walk down, check your target, B.S. with your shooting buddy, reload and shoot some more! Just give it some time to cool down is the important thing. Besides, you get a Mannlicher stock for style points, not pin-point accuracy. But remember, IT'S A CZ, you won't be dissapointed!! Good luck!
