Half-MOA with Factory Ammo? Weatherby VMC Comes Close

Weatherby Vanguard Modular Chassis PRS rifle .308 Winchester American Rifleman
Three factory ammo types shot 0.53″, 0.55″, and 0.57″ respectively. That’s impressive.

Chassis rifles are hugely popular for PRS/NRL practical rifle competition. There are many good options for Production Class. You may not know that Weatherby, a company that built its reputation on hunting rifles, offers a great-shooting chassis rifle for PRS comps and other tactical disciplines.

Called the Vanguard® Modular Chassis (VMC), this rig has shown remarkable accuracy. Vanguard’s VMC 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 (5-Shot Groups)
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 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 types of factory ammo, with three of types registering 0.57″ or better.

The rifle delivered near-half-inch 5-shot groups with two types of Hornady ammo along with Black Hills 168gr. The worst group of six ammo types tested, Black Hills 175gr, was 0.76″, still very impressive for factory fodder. With good hand-loads this gun could go well under half-MOA (for five shots).

Vanguard Modular Chassis FIVE-SHOT Factory Ammo Test Groups:

0.53 inches | Hornady 168gr Match BTHP (2718 fps)
0.55 inches | Hornady 155gr Steel Match (2612 fps)
0.57 inches | Black Hills 168gr BTHP (2608 fps)
0.66 inches | Federal Premium 168gr MatchKing BTHP (2659 fps)
0.70 inches | Hornady 155gr American Gunner (2697 fps)
0.76 inches | Black Hills 175gr BTHP (2603 fps)

NOTE: Group sizes are for 5-shot groups shot from bench at 100 yards with Caldwell pedestal rest and rear sandbag. Pentax Lightseeker 6-24x50mm scope. Velocities in FPS from PACT Chronograph.

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.”

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).
