Frequently Asked Questions
Can the Gamo GP-20 shoot pellets as well as BBs?
No — the Gamo GP-20 Combat is designed specifically for .177 caliber steel BBs. It is not compatible with lead pellets. Using anything other than the recommended steel BBs may damage the magazine or internal components and could void any manufacturer warranty.
How many shots can I get from a single 12-gram CO2 cartridge?
Under normal conditions and moderate temperatures, a single 12-gram CO2 cartridge typically yields approximately 40–60 shots from the Gamo GP-20, though this can vary based on temperature, shooting pace, and how consistently the trigger is cycled. Cooler weather tends to reduce CO2 efficiency and may lower both shot count and velocity.
Is the Gamo GP-20 suitable for indoor target shooting?
Yes, with the appropriate safety setup. At 400 fps, the GP-20 is well-suited for indoor plinking with a proper BB trap or pellet catcher to prevent ricochets. Always ensure your backstop is rated for steel BBs, as they can bounce back more readily than lead pellets. Eye protection is strongly recommended at all times.
