I have a heavy varmit I bought about 2.5 years ago used. I was told it came from the Winchester custom shop but sounds exactly like the gun you described. It has a 24" heavy stainless barrel, blued action and sits in a HS Precision stock. It says heavy varmit on the barrel. If this is the same gun you are considering purchasing I would definately recommend it. The one I have is a real tack driver, and I love the HS precision stock. I got mine as a package with scope, bipod, and sling it looked like new when I got it. I've only put a few hundred rounds thru it but it likes everything I fed it.
