Vanguard Modular Chassis Rifle — Half-MOA with Factory Ammo

Weatherby has a new modular rifle for PRS comps and other tactical disciplines. Called the Vanguard® Modular Chassis (VMC), this rifle features a Modular Driven Technologies (MDT) aluminum stock, Luth AR MBA-1 buttstock, and 22″ heavy barrel. The Weatherby Vanguard action is fitted with an adjustable 2-stage trigger. Priced at $1519.00 MSRP, this rifle can be campaigned in the PRS “Production Class”, which limits complete rifles to $2000.00 without optics. The rifle is offered in three chamberings: .223 Rem, 6.5 Creedmoor, and .308 Winchester.

Weatherby says its Vanguard Modular Chassis tactical rifle is very accurate. To back that claim, Weatherby offers a SUB-MOA accuracy guarantee — Weatherby guarantees the rifle will shoot .99” or smaller 3-shot groups at 100 yards when used with Weatherby® factory or premium ammunition.

Near Half-MOA Accuracy with Factory Ammo
It turns out Weatherby’s accuracy claims are conservative. This tactical rifle is closer to a half-MOA rig than a 1-MOA gun. American Rifleman recently tested a .308 Win version of this rifle and recorded really stellar accuracy — close to half-MOA. What’s more, this rifle is not fussy — with a 1:10″-twist barrel it proved very accurate with six different types of factory ammo.

In fact, the rifle delivered near-half-inch 5-shot groups with two types of Hornady factory ammo, and the worst group (of six ammo types) was 0.76″, still very impressive for factory fodder. With good hand-loads this gun could go well under half-MOA (for five shots).

The accuracy testing was done by gunwriter Mike Detty, who notes: “My single best group was fired with Hornady’s Match 168-gr. BTHP ammunition. Five shots measured just slightly more than a half-inch. Hornady’s 155-gr. Steel Match ammo wasn’t far behind with a group of .55″. Also accounting for the small groups is the VMC’s wonderful trigger. It is a two-stage affair and the first stage has about 3/8” take up with about a pound of pressure until it reaches the second stage where another 1 ¾ lbs. was required to break the shot.”
