In the 1960's, Roy Weatherby recognized the need for a more affordable rifle that could chamber his signature magnum cartridges. Having just partnered with Howa to produce Mark V actions and seeing the precision and attention to detail that this Japanese manufacture provided, the Vanguard project was born. Starting with a Howa two-lug push-feed action, a number of Weatherby signature safety features were incorporated, including a fully shrouded bolt and three gas ports on the bolt body, both providing protection in the event of an ammunition failure.
