I have a winchester 70 in 7mm rem mag, and its one of my favorite rifles. Shoots great, well balanced, and well made. The only problem I had is that the factory synthetic stock was crap, so I put a hogue overmolded stock on it, now its awesome! Great deer rifle, but you got to be careful with hotter loads or they can mess up some meat, so I try to shoot em in the neck. As for sighting in either get someone to bore sight it or buy a bore sighter so you'll at least be on paper then just adjust your scope like any other rifle. Its a great rifle, and it didn't get called "the riflemans rifle" for nothing.
