Gamo Expander Expansion 4.5 mm 7.56 gr – 250 pcs

Gamo Expander Expansion 4.5 mm 7.56 gr

The Gamo Expander Expansion 4.5 mm is a lead diabolo pellet weighing 7.56 gr with a distinctive hollow-point design. A small central point is surrounded by a cavity in the head. This design combines penetration with the potential for deformation and expansion on impact.

At 0.49 grams, the Expander is a relatively light pellet in 4.5 mm / .177 calibre. Its distinctive head design gives it different characteristics from traditional round-head, flat-head or conventional pointed pellets.

Hollow point with a central point

The most distinctive feature of the Gamo Expander is its hollow-point head with a central point. The central point assists with the initial impact, while the surrounding cavity is designed to encourage deformation of the pellet head. This gives the Expander characteristics of both a pointed pellet and a hollow-point pellet.

Gamo describes the Expander as a pellet designed for strong impact and expansion. The actual amount of deformation depends on several factors, including impact velocity, shooting distance and the material being hit.

Penetration and energy transfer

Because of its combined head design, the Expander is not focused solely on penetration. Its construction is intended to allow the lead to deform after the initial impact, helping to transfer energy to the target.

Lead is a relatively soft material and can deform under sufficient impact. This effect may be more pronounced in softer target materials than in very hard materials.

For different 4.5 mm airguns

The Gamo Expander can be used in various 4.5 mm / .177 airguns, including spring-powered, gas-ram and PCP airguns. At 7.56 gr, it is a relatively light pellet that can be tested in a wide range of airguns in this calibre.

Accuracy will always depend on the individual airgun and barrel. It is therefore advisable to test the Expander in your own airgun and compare its grouping with round-head, pointed and other hollow-point pellets.

What is the Gamo Expander suitable for?

The Expander is particularly interesting when penetration, deformation and energy transfer on impact are important characteristics. For shooting paper targets, a flat-head pellet is generally a more suitable choice, while a more aerodynamic round-head pellet is usually preferred for precision shooting at longer distances.
