The Gamo "Big Cat 1400" is often confused with the Gamo Big Cat 1250 or 1300 . Gamo did produce a Big Cat 1400 primarily for certain markets (sometimes labeled as the Hunter 440 or similar in other regions), but the most common "Big Cat" models are the 1250 and the 1300. The number refers to the velocity in feet per second (FPS) with alloy pellets.

Ensure the scope mounts are tightened evenly. Use the recoil pin to prevent the scope from "walking" backward due to the rifle's double-recoil.

Never manually disengage the safety until you are on target and ready to shoot. Do not rely on the safety 100% – it is a mechanical device that can fail. This step-by-step guide mirrors the original user manual
Never point the barrel at anything you do not intend to shoot.
Oil in the compression chamber causes “dieseling” – explosive ignition that can destroy the piston seal, spring, and possibly injure the shooter.
