Gamo Expander Pellets – 5.5mm

Verified specifications

Why choose this pellet

Choose the 5.5 mm Expander when a hollow-point Gamo pellet is appropriate and the airgun is explicitly chambered for 5.5 mm. It is not interchangeable with the lighter 4.5 mm reference.

Compatibility and responsible use

• Use only in an airgun marked for 5.5 mm (.22).
• Check the airgun and magazine manual before use; calibre alone does not confirm rotary-magazine fit.
• Test grouping under the same safe conditions because individual barrels can prefer different suitable pellets.
