I found a Vanguard in 257 Weatherby locally that I'm thinking about buying until I get a custom rifle built. It's the original Vanguard series with the plain black synthetic stock. Overall condition is pretty good, seller is asking $350 for it. What kind of groups do these "value line" Weatherby's shoot? I have never owned a Weatherby branded rifle. Looking for some input on whether to buy this rifle or just save my money towards the custom gun.
