I was looking at the 770 in .30-06 about two months ago and opted to spend the extra $100 for a Savage 110 instead. From what I understand, the barrel is pressed together on the 770 and is not replaceable. The other thing I didn't like to much was the appearance of the plastic they used on the stock and the sling studs being molded into the plastic. Despite those two things, I hear it's a pretty accurate gun out of the box. A friend at work has one in 7mm along with his brother and father and they all seem to be pleased with them.
