This article highlights the Accuracy Guarantee corresponding to the specific serial number prefixes of rifles produced by Weatherby. Note: Not all prefixes fall under the current Sub-MOA Accuracy Guarantee.
Currently, Weatherby guarantees Sub-MOA accuracy within Two-Years of Verified Purchase Date to the Original Purchaser of the firearm. This applies to all Weatherby® Mark V® rifles with a serial number prefix of “WY, PM and PS”, Model 307™ rifles with a prefix of "AW", and Vanguard® Series 2 rifles with a serial number prefix of “VB”. These rifles are guaranteed to shoot a .99″ or better 3-shot group at 100 yards from a cold barrel when used with premium (non-Weatherby calibers) or Weatherby factory ammunition within Two-Years of the Verified Purchase Date, to the Original Purchaser only.
All other Mark V® rifles with a 5 digit numeric number, B, C, H, M, P, S, AB, AS, BP, BW, PB, SB, SS, SW, WB, WS, as well as all other Vanguard® rifles with serial numbers beginning with V, VL, VS, or VX, are guaranteed to shoot a 1 1⁄2” or better 3-shot group at 100 yards from a cold barrel when used with premium (non-Weatherby calibers) or Weatherby® factory ammunition within Two-Years of Verified Purchase Date to the Original Purchaser.
