I’ve been weighing two of the absolute finest dangerous game bolt-actions on the market today. Both are phenomenal modern iterations of the Mauser 98 platform, but their engineering philosophies couldn't be more different. I put together this head-to-head comparison analyzing the subtle mechanics, wood value, barrel profiles, and magazine feeds of the commercial Heym Martini Express versus the Rigby Big Game series. I have enlisted the help of AI to produce this!
I’ve included a poll as well although I suspect the Rigby will dominate due to popularity on AH. For those who have logged real miles on safari with either, how do you value mechanical refinement versus historical pedigree when you are down in the thick stuff? Here is my breakdown:
The Clash of the Titans: Heym Martini Express vs. Rigby Big Game
When tracking dangerous game across the world's most unforgiving bushveldt, your rifle ceases to be a sportsman's luxury—it becomes life insurance. For the discerning hunter seeking the pinnacle of modern dangerous game bolt-actions, two European masterpieces dominate the conversation: the German-engineered Heym Martini Express and the British-born John Rigby & Co. Big Game.
Both rifles are built around the legendary, unyielding Mauser 98 controlled-round-feed concept, ensuring flawless cycling when the distance closes. Yet, despite sharing the same mechanical lineage, these two icons deliver vastly different philosophies on the premium dangerous game rifle.
The Heym Martini Express
Debuted to commemorate the pinnacle of big-bore performance, the Heym Express is a tour de force of modern precision engineering blending seamlessly with classic aesthetics. It is widely considered one of the most mechanically perfect dangerous game rifles ever machined.
The Pros
The Cons
The Rigby Big Game
When John Rigby & Co. returned to London, they re-released the Big Game rifle utilizing authentic Mauser actions stepped directly from original factory blueprints. It is a rifle drenched in history, carrying the spiritual weight of classic twentieth-century exploration.
The Pros
The Cons
The Verdict
Choosing between these two is a matter of prioritizing the head versus the heart.
The Heym Martini Express is arguably the superior tool—it represents the absolute zenith of modern machining, flawless, cartridge-specific feeding reliability across every caliber, an elegant high-capacity flush magazine, a highly field-durable oil finish, in-house Krupp steel barrel mastery, and unparalleled wood-to-cost value. The Rigby Big Game, however, is the superior heirloom—it captures an irreplaceable romance, iconic British styling, and an investment pedigree that transcends mere metallurgy.
Personally, I’ll choose performance over pedigree, so my choice is the Heym Martini Express, your mileage may vary.

The Heym Martini Express
Debuted to commemorate the pinnacle of big-bore performance, the Heym Express is a tour de force of modern precision engineering blending seamlessly with classic aesthetics. It is widely considered one of the most mechanically perfect dangerous game rifles ever machined.
The Pros
- True Caliber-Specific Architecture: Heym is the only gunmaker in the world that machines the action geometry and internal magazine rails from the ground up for the specific dimensions of every individual cartridge they chamber. From the sweeping taper of the .375 H&H to the fat, unbelted profile of the .404 Jeffery or .416 Rigby, the internal walls perfectly form to that exact round. This eliminates the need for cheap magazine spacers or generic receiver cuts, completely preventing bullet-nose deformation under heavy recoil and guaranteeing ultra-smooth, grease-slick feeding every single time.
- High-Capacity Flush Magazine Design: One of Heym’s most brilliant engineering achievements is its unique magazine configuration. By widening the internal architecture of the action belly, Heym maximizes cartridge capacity—holding an optimal 4+1 rounds of massive big-bore calibers—while keeping the floorplate completely flush with the bottom of the wood stock. This gives the rifle an incredibly clean profile and removes any protruding steel to snag on clothing or brush when carrying the rifle at its balance point.
- The Ralf Martini Design: Heym partnered with renowned custom rifle builder Ralf Martini to completely overhaul the stock and profile. Reminiscent of best-grade "between-the-wars" English sporting rifles, Martini's straight-comb architecture directs recoil straight back into the shoulder, giving the rifle a natural, instinctive, shotgun-like pointability for rapid follow-up shots.
- Superior, Field-Ready Wood & Value: Heym historically offers significantly higher-grade walnut upgrades at a much lower cost than its London competition. Furthermore, Heym employs a highly robust, traditional hand-rubbed oil finish. This finish is exceptionally durable against the elements, breathable, and incredibly easy to touch up or blend seamlessly in the field if it scratches, unlike heavy lacquers or complex synthetic coatings.
- In-House Krupp Steel Mastery: Heym is one of the exceptionally rare premium gunmakers that manufactures its own barrels entirely in-house. Cold-hammer forged from legendary Krupp steel, these barrels are celebrated for their incredible strength, thermal stability, and world-class accuracy. Because Heym controls the entire forging process, the weight distribution and barrel profile are flawlessly integrated into the action, giving the rifle an exceptionally balanced, lively feel in the hands.
- Integral Scope Mounts: The double-square bridge receiver features milled, integral 19mm dovetail bases. This eliminates the risk of mounting screws shearing off or shifting under the brutal recoil of heavy safari calibers.
The Cons
- The "German vs. British" Identity: While exquisitely finished and styled along British lines, the Heym possesses a distinctly crisp, clinical German aesthetic. It lacks the historic, romantic "olde-worlde" mystique that many dangerous game traditionalists crave.
- Rarity: Sourcing a specific configuration of a Martini Express can require patience or custom ordering due to their low-volume, bespoke manufacturing process.
The Rigby Big Game
When John Rigby & Co. returned to London, they re-released the Big Game rifle utilizing authentic Mauser actions stepped directly from original factory blueprints. It is a rifle drenched in history, carrying the spiritual weight of classic twentieth-century exploration.
The Pros
- Unmatched Heritage & Pedigree: Buying a Rigby is an emotional investment. Walking into the bushveldt with a "London Rigby" links you directly to the golden era of dangerous game hunting. The prestige of the name is unrivaled.
- Supreme Value Retention: Rigby rifles are functionally blue-chip investments. Because of the London ledger books and brand mystique, they historically appreciate or maintain their value incredibly well on the secondary market.
- Classic British Ergonomics: The stock lines are slender, elegant, and traditional. The grip angle and slim forend are optimized for a secure, comfortable hold through long days on the tracks.
The Cons
- The Protruding Drop-Box Magazine: To achieve a comparable dangerous game firepower capacity (4+1 rounds in larger calibers like the .416 Rigby), the commercial Rigby Big Game relies on a prominent Oberndorf-style protruding drop-box magazine that extends visibly below the bottom of the stock line. While it keeps your capacity high, it breaks up the clean, traditional lines of the rifle and creates a bulky steel edge exactly where a hunter naturally wants to wrap their hand when carrying the rifle at trail-arms.
- Generic Action Limitations: Because Rigby relies on standard, authentic Mauser-produced magnum actions as their base, they must use traditional gunsmithing methods—such as internal block spacers or ground-down rails—to adapt the generic receiver to various calibers. As a result, they can occasionally feel slightly stiff or "gritty" when brand new compared to the meticulously toleranced, inherently caliber-specific geometry of the Heym, requiring a breaking-in period to smooth out.
- The Premium Cost of Luxury: Rigby's pricing structure reflects its elite London heritage. Getting upgraded, highly figured walnut on a Big Game rifle comes at a massive financial premium compared to Heym's accessible wood pricing tiers.
- Outsourced Barrel Blanks: While Rigby regulates and finishes their rifles beautifully, they do not forge their own raw barrel blanks in-house like Heym does. They rely on external manufacturers to source their raw steel and base contours, stepping away from total internal quality control.
- Scope Mounting Vulnerability: Unlike the Heym’s integral bridges, the standard Rigby Big Game relies on traditional bridges drilled and tapped for opting bases. While incredibly strong, it introduces a mechanical point of failure (screws) that the Heym eliminates.
The Verdict
Choosing between these two is a matter of prioritizing the head versus the heart.
The Heym Martini Express is arguably the superior tool—it represents the absolute zenith of modern machining, flawless, cartridge-specific feeding reliability across every caliber, an elegant high-capacity flush magazine, a highly field-durable oil finish, in-house Krupp steel barrel mastery, and unparalleled wood-to-cost value. The Rigby Big Game, however, is the superior heirloom—it captures an irreplaceable romance, iconic British styling, and an investment pedigree that transcends mere metallurgy.
