I bought a new one in 6.5X55 about 15 months ago. It's a fine rifle, but....
The barrel was riding one side of the stock very hard. In order to fix this, I removed the factory hot glue bedding and rebedded with the barrel floating. It will shoot at an inch or under with 120, 140 and 160 grain handloads. I never shot it with the barrel riding, as I knew what the outcome would be.
The other main problem I have, is that it will not reliably eject cases. They fall free from the extractor prior to being kicked out of the rifle. I have both tuned the extractor and replaced the extractor, to no avail. I believe there is a tolerance stack up problem with the machining on the bolt face. So I am at the point of either sending it back to Winchester, or dumping it. Knowing what I know now, I wouldn't bother with the Winchester, but rather buy a Tikka T3. In fact, I also recently bought a Remington 700, which has fewer problems than the Winchester. This makes me sad, as I am a Winchester guy, but the rifle shouldn't leave the factory like it did, for what they cost.
Of course, other peoples experiences will be different.
