Hi there, Weatherby Vanguards sold in the USA are rebadged Howa 1500 rifles, made in Japan. I don't know if they're the same thing on your side of the pond or not. If they are the rebadged Howas, the 308 should be a short action, and it should take the same scope bases as a Remington 700.Weatherby Vanguard. Included Accessories: Med Base, Ring. Fit perfectly on my Weatherby Vanguard in mounting Leupold scope. Did my research beforehand and found these to be recommended for the Vanguard.
