Four pounds is a scaped rimfire expectation as opposed to a center fire bolt gun with threaded muzzle and an accuracy assurance. Weatherby Mark V Backcountry Capra bends as far into that cognitive dissonance as its lightest trims, a 4 lb production bolt-action with a 17-inch barrel, in either a .308 Winchester or lighter, weighing just 6.2 lbs with that lighter barrel installed. The scale reading is less interesting than the engineering story, and the attention-grabber is immediately obvious when one picks up the magazine. Today, mountain rifles are not merely their established patterns cut down to a smaller size; the modern models are designed as systems in which every design choice is returning its weight, or must be reduced.
At the heart of the Capra is a titanium Mark V action, but using the slimmer six-lug design of Weatherby, with the short, quick 54-degree bolt lift that has long been a part of the Mark V heritage. The weight delta does not sell fog–titanium is hard to machine, and the reason of making use of it in this case is that it will give steel-like strength at about 42 percent of the weight. Combine that with a skeletonized bolt handle, a shaved internal mag system, and a barrel profile that is in all the ways unashamed of being a pencil in front of the chamber, and the ounces begin to be shaved away in significant chunks as opposed to gimmicks.
The brief “no spare metal” is even telegraphed by the barrel. Weatherby selected the use of double helical fluting and a 1/ 2x 28 threaded muzzle, and the rifle is being sold outfitted with an Accubrake ST. It is not the mixture of style; it is how the featherweight rifle can be made workable when the shooter is lying flat on a pack or is hustling him/herself into an embarrassing kneel on a hillside. Weatherby also bases its hat on a cold-barrel guarantee, with sub-MOA at 100 yards with factory or premium ammunition. Outside testing range has indicated group sizes around three-quarter inch and some loads becoming even smaller, and that is significant since ultra-light rifles have less inertia to conceal the error committed by the shooter once the recoil and therefore the gun start moving.
The fact that recoil control is there is where Capra engineering turns into a balancing act instead of a one-minded race to the weight. A four pound.308 is not going to act like a nine pound chassis rifle, and nothing in the design is going to act like it. In its place, Weatherby piles on the mitigation: the muzzle brake in the front, and a heavy 3D HEX recoil pad in the back. The honeycomb construction of the pad is no gimmick, that it is meant to extend the recoil impulse, and the brake is claimed to decrease felt recoil by up to 53%. Those figures do not disarm physics, but do shift the experience of this rifle, between its punishment and its labor, to a more ludicrous and reflexive than its firing.
The other half of the equation is the stock. The Capra features a Peak 44 carbon-fiber stock with rough weight-saving cutouts and geometry that is designed to be used in the field or at least not to be hand-resting-comfortable on the bench-rest-with-a-tripod-scope. Even Weatherby removes what most hunters find as “nice to have” hardware: the Capra uses a blind magazine instead of a hinged floorplate, concentrating on simplicity and grams saved. Capacity is maintained low – usually 2+1 – due to the fact that this is a carry, first shot, and disciplined follow-up rifle.
Caliber choices are not confined to .308 and 6.5 Creedmoor but instead go into the Weatherby RPM family, with a 25 WBY RPM, which is built around modern heavy-for-caliber bullets and fast-twist barrels. Regardless of the familiar or newer geometry of the case, the same through-line applies: a hunter will make use of the familiar or the newer case, but the through-line remains the same, specific to the engineering constraint set, rather than a vibe. A four pound hit without leaning a carbon-wrapped barrel is not a matter of lightness, it is what had to be so that it could be shoot able.
