Why didn't my Vanguard® rifle come with a factory shot target?
In an effort to contain costs and keep the Vanguard as affordable as possible, we discontinued the inclusion of a factory-shot target in each Vanguard box in July 2009. However, every Vanguard rifle continues to be made to our exacting specifications and quality control. And as always, it is backed by a written accuracy guarantee (Guaranteed to shoot a 1 1/2" 3-shot group at 100 yards from a cold barrel when used with premium (non-Weatherby calibers) or Weatherby factory ammunition).
Does Weatherby® have an Accuracy Guarantee? And what should I do if my rifle does not shoot within the guarantee?
All Weatherby® (Mark V® and Vanguard®) rifles are guaranteed to shoot a 1- 1/2" (or better) 3-shot group at 100 yards from a cold barrel when used with Weatherby® factory ammunition. For Weatherby® rifles chambered in non-Weatherby® calibers, the guarantee is effective when premium loads are used. If for some reason your rifle does not shoot within the guarantee, Weatherby advises you to send the rifle to a Weatherby-authorized service center. After being tested by the service center, if indeed it does not shoot within the guarantee and the rifle has not been altered, the service center will repair the rifle under warranty, or forward it to the factory for inspection and replacement approval, if deemed necessary.
Weatherby guarantees that your rifle will shoot at a minimum one bullet type and grain weight within our accuracy guarantee. We do not guarantee that every bullet type or grain weight for every caliber will shoot within our accuracy guarantee.
Select models (SUB-MOA) are guaranteed to shoot .99" or less at 100 yards when used with specified Weatherby® factory or premium ammunition (3-shot group).
