Having had mine for about four years now - I love it! Smallest groups have been under 1/2 inch at 100 yards, using moly-coated 45 grain V-Max loads from a gunshow reloader I deal with. Factory Winchesters do so-so at about 2 inch groups.
The two main problems are a very stiff and gritty trigger, and a stiff break-open lever (hard on the thumb!). Scoping it is tricky too, as the rail on top is an odd design.
Overall, a good gun with lots of potential - but it does need some work to smooth it.
