Gamo Expander Expansion 5.5 mm 15.42 gr – 250 pcs

Gamo Expander Expansion 5.5 mm 15.42 gr

The Gamo Expander Expansion 5.5 mm is a lead diabolo pellet weighing 15.42 gr with a hollow-point head. Its head design is intended to deliver high energy transfer on impact and, depending on velocity and target material, allow the pellet to deform and expand.

At 1.00 gram, the Expander is a medium-weight pellet in 5.5 mm / .22 calibre. The combination of its traditional diabolo shape and hollow-point head gives it different characteristics from conventional round-head or pointed pellets.

Hollow-point design for expansion

The main feature of the Gamo Expander is its hollow-point head. The cavity in the front of the pellet is designed to encourage deformation of the lead on impact. With sufficient impact velocity, the head can widen and transfer more of its energy to the target.

The actual amount of expansion depends on several factors, including pellet velocity, shooting distance and the material being hit.

Designed for energy transfer

While round-head pellets are often selected for their aerodynamic properties and pointed pellets place more emphasis on penetration, the Expander is designed around expansion and energy transfer on impact.

The pellet is made from lead, a relatively soft material that can deform under sufficient impact. This characteristic works together with the hollow-point design of the Expander.

For different 5.5 mm airguns

The Gamo Expander can be used in a variety of 5.5 mm / .22 airguns, including spring-powered, gas-ram and PCP airguns. At 15.42 gr, it falls within a commonly used weight range for this calibre.

Accuracy and the amount of expansion can vary depending on the airgun, velocity and shooting distance. It is therefore advisable to test the Expander in your own airgun and compare its grouping with other pellet designs.

Expansion or penetration?

The Expander is distinguished within the Gamo pellet range primarily by its hollow-point head. If penetration is the main requirement, a pellet specifically designed with a pointed head may be a better choice. The Expander is intended for shooters looking for a pellet designed to encourage deformation and energy transfer on impact.
