Brief History & Lineage

Weatherby Inc. was founded in 1945 in South Gate, California by Roy Weatherby (relocated to Sheridan, Wyoming in 2018). The Mark V action and the Weatherby proprietary magnum cartridges (.257, .300, .340, .378, .460 Wby Mag) defined the American magnum-rifle category. Within the catalog, Weatherby positions itself among peers including Browning, Christensen Arms, Howa.

Variant & Year-of-Manufacture Notes

The Weatherby Mark V Stainless has been offered across multiple production years with variation in stock material, finish, and barrel length. Early-production examples typically command a modest premium over late-production guns of the same configuration. Watch for aftermarket modifications — refinishes, drilled-and-tapped receivers on classic pieces, replacement stocks, and trigger swaps — all of which can shift used value. Original-condition examples with matching serials, factory boxes, and manuals trade at the top of the range for the model.

Ammunition & Shooting Notes

The .300 Win Mag is used for elk, moose, long-range hunting, military sniper. Premium hunting loads (nosler, hornady) and mk 248 mod 1 military precision. Modern factory loads from American, European, and Asian manufacturers all run well in this platform, and reloaders enjoy a wide range of bullet and powder combinations.

How It Compares

The Weatherby Mark V Stainless occupies a market position comparable to offerings from Browning, Christensen Arms, and Howa. Buyers cross-shopping these brands typically prioritize long-range hunters — and once they’ve committed to Weatherby, brand loyalty tends to be strong because of dealer network and parts availability. Used-market resale for a comparable-condition gun from these peer brands trades within roughly ±15% of the Weatherby Mark V Stainless depending on the specific variant and year.

What’s a Used Weatherby Mark V Stainless Worth?

Private-sale ranges for a working, no-rust Mark V Stainless in 2026 fall in four bands:

• Beater / heavily used: $350–$525 — significant wear, action functional, may need cleaning or minor service
• Average / honest used: $475–$725 — normal handling marks, mechanically sound, ready to shoot
• Excellent / lightly used: $650–$1000 — minimal wear, clean bore, original box and paperwork a plus
• New-in-box or unfired: $825–$1300 — at this price, the calculation usually flips toward buying new instead

Add a premium for documented early-production examples, original box and accessories, or limited-run variants. Subtract for refinished surfaces, aftermarket modifications a buyer would have to reverse, or signs of hard use.

Who Buys It?

The typical Weatherby buyer profile includes long-range hunters, magnum-cartridge enthusiasts, mountain hunters. The rifle format and the .300 Win Mag chambering further focus the audience. Used-market liquidity is solid — list a clean example at fair market on GunBroker, Armslist, or a local board and it generally moves inside two to three weeks. Dealer trade-in offers typically run 20–30% below private-sale; if you have time to list, private sale captures the premium.
