Weatherby Mark V BC Carbon .240 Wby Mag 24″ LH

About this product

The Weatherby Mark V BC Carbon .240 Wby Mag 24″ LH is a purpose-built left-hand bolt-action rifle that combines a BSF carbon-fiber barrel and carbon-fiber stock to achieve a 5.9-lb field weight, making it one of the most practical mountain hunting platforms in its class. Chambered in .240 Weatherby Magnum, it maintains a 44.5-inch overall length while delivering controlled, repeatable shots through a TriggerTech trigger and 3D HEX recoil pad system. The Patriot Brown Cerakote finish provides a low-profile, weather-resistant surface for operations from alpine timberline to desert foothills.

What is the Weatherby Mark V BC Carbon used for?

This rifle is engineered for high-country hunting and precise shots beyond conventional centerfire ranges. Its primary application is for experienced shooters pursuing medium-sized game like mule deer, pronghorn, and mountain goats at distances from 200 to 500 yards. The 1-in-10 twist rate stabilizes factory-loaded 87-grain to 100-grain bullets effectively, and the left-hand bolt orientation provides natural manipulation for southpaw shooters without compromising cheek weld during follow-up. Compared to our stocked Stevens 334 in .308 Win, which is configured for heavier bullets and brush shooting, the Mark V BC Carbon prioritizes weight savings and flat trajectory over terminal energy at close quarters.

How does the Weatherby Mark V BC Carbon compare to the Stevens 334 .243 Win?

The Mark V BC Carbon is objectively superior for long-range, lightweight hunting, though it commands a $2,300 premium over the Stevens 334. Where the Stevens 334 in .243 Win uses a 20-inch chrome-moly barrel and traditional synthetic stock weighing approximately 6.8 lbs, the Mark V employs a BSF carbon-wrapped barrel and full carbon-fiber stock to shed nearly a pound. The Weatherby's TriggerTech trigger breaks at a consistent 2.5 lbs out of the box with minimal overtravel, while the Stevens adjustable trigger typically requires tuning to achieve comparable pull quality. For backcountry hunters counting ounces and needing first-round precision at elevation, the Weatherby justifies its cost; for woodland deer stands or general range use under 300 yards, the Stevens represents competent value.

What does it weigh and what are the dimensions?

This rifle weighs 5.9 lbs (94.4 oz) unloaded and measures 44.5 inches in overall length. The barrel itself is 24 inches long with a left-hand 5/8×24 thread pattern for suppressor or muzzle brake attachment, and the carbon-fiber stock has a length of pull measuring 13.5 inches. The magazine holds 5 rounds plus one in the chamber, and the 1-in-10 twist rate dictates optimal bullet weights between 85 and 105 grains for the .240 Weatherby Magnum cartridge. For comparison, a similarly configured all-steel rifle would typically exceed 7.5 lbs, representing a 27% weight reduction.

Who is this NOT for?

This rifle is ill-suited for new shooters, budget-conscious buyers, or those requiring high-volume range sessions. The .240 Weatherby Magnum is a proprietary cartridge with limited factory ammunition availability and costs approximately $85 per box of 20 rounds, making practice expensive. The carbon-fiber barrel, while thermally stable for hunting shot strings, is less tolerant of sustained rapid fire than a chrome-lined steel barrel and can show carbon “cooking” after 10-12 rounds fired consecutively. Left-hand shooters who prefer a right-hand bolt for offhand operation, or hunters in dense timber who rarely engage beyond 150 yards, will not realize the platform's advantages.

What's in the box?

You receive the rifle with factory-mounted 3D HEX recoil pad, a single 5-round detachable box magazine, and a thread protector for the muzzle threads. Weatherby does not include scope rings, a sling, or a hard case—expect only the rifle, magazine, and basic documentation. The receiver is pre-drilled and tapped with a standard #8-40 screw pattern for scope base installation, but you must supply your own bases and rings. The TriggerTech trigger is factory-set and should not require adjustment for most users.

Is the Weatherby Mark V BC Carbon worth it at $3,049?

Yes, if you are a left-hand shooter who requires a durable, lightweight rifle for extended carries and precise shot placement at extended ranges. The $3,049 MSRP covers the premium carbon-fiber barrel and stock construction, Cerakote corrosion resistance, and the match-grade trigger—components that would cost over $1,200 to retrofit onto a conventional rifle. For a dedicated mountain hunter facing 3,000-vertical-foot climbs, saving 1.6 lbs over a standard-weight rifle translates directly to endurance and shot stability. If your hunting consists of driving to box blinds or shooting from established benches, invest the savings in optics and ammunition for a platform like the Stevens 334.
