Gamo Lethal 4.5mm / .177 Cal Lead-Free Pellets
The Gamo Lethal 4.5mm / .177 Cal is a specialist lead-free airgun pellet with a distinctive two-piece construction. Instead of a conventional all-lead diabolo, the Lethal combines a metal body with a long polymer skirt, giving it the characteristic black-and-metal appearance associated with this pellet. Gamo lists the pellet at 0.36 g (5.55 gr) and supplies it in a 100-pellet tin.
The front of the pellet has a rounded metal nose, while the rear section is formed from polymer. Product descriptions identify the metal section as steel, with some specifically describing the nose as copper-plated or copper-coloured.
Two-Piece Lead-Free Construction
One of the defining features of the Gamo Lethal is its construction. Gamo describes it as a design made from a steel body and polymer skirt, rather than traditional lead.
The result is a pellet that looks very different from a conventional lead diabolo. The black polymer skirt forms the rear of the pellet, while the metal nose provides the contrasting front section.
This construction is particularly relevant for shooters looking specifically for a lead-free 4.5mm / .177 pellet rather than a standard lead projectile.
4.5mm / .177 Calibre
The Gamo Lethal 4.5mm is designed for 4.5mm (.177 calibre) airguns. Gamo’s official catalogue lists the Lethal under its 4.5mm ammunition range with a reference number of 6322740-B, a weight of 0.36 g / 5.55 gr and a quantity of 100 pellets.
Always confirm the calibre and pellet dimensions recommended for your particular air rifle or pistol before use.
0.36 g / 5.55 gr Pellet Weight
Each Gamo Lethal 4.5mm pellet weighs 0.36 g (5.55 grains). This relatively light projectile weight is one of the main specifications to consider when comparing it with other .177 calibre pellets.
Gamo specifically promotes the Lethal’s design for aerodynamic stability and trajectory characteristics. Its official product information also states a claim of improved precision compared with standard pellets.
Designed for Penetration and Specialist Airgun Use
The Gamo Lethal 4.5mm has been developed around a metal-fronted, polymer-skirted construction rather than a traditional soft lead head. Gamo describes the pellet as offering penetration and stable flight characteristics, while its packaging and retailer descriptions have positioned it for pest-control and recreational applications.
Because pellet performance is affected by the power and design of the individual airgun, results can vary between rifles and pistols. Compatibility should therefore be checked against the manufacturer’s recommendations for the specific airgun.
100 Pellets per Tin
Each tin contains 100 Gamo Lethal 4.5mm pellets. The 100-count configuration is confirmed in Gamo’s current catalogue as well as Gamo South Africa’s product listing.

What Makes the Gamo Lethal Different?
The main distinction is its lead-free, two-material construction. Rather than using a conventional lead body, the pellet combines a metal front section with a polymer skirt. This gives the Gamo Lethal its distinctive appearance and separates it from ordinary lead .177 diabolo pellets.
