More pumps raise velocity up to the manufacturer's maximum, so one airgun covers close-range plinking and harder-hitting shots. No CO2 or external air source is needed.About the CaliberThe .177 caliber (4.5 mm) is the most common airgun caliber. Its light, fast projectiles shoot flat, which makes it a favorite for target shooting, plinking and small pests at modest ranges.Specifications ExplainedCrosman rates velocity at Up to 700 fps. Published velocity is measured with the ammunition type the manufacturer lists; heavier pellets will shoot slower but often carry more energy.Muzzle energy is listed as 7 ft-lbs.

A rifled barrel spins the pellet for accuracy.Trigger: Single Stage. A predictable trigger is one of the biggest factors in accurate shooting.For aiming, the manufacturer lists Elevation Adjustable Pin. Check the rail type before buying rings or a dot sight.The safety is listed as Crossbolt. Learn how it works from the owner's manual before loading.Getting Started and CareBefore the first session, read the owner's manual, check that the gun is unloaded, and set up a safe backstop or pellet trap. Shoot from a rest to confirm where the gun hits at your usual distance, then adjust the sights or scope.Try several brands and weights of quality .177 pellets of the type the manufacturer lists. Airguns often prefer one pellet over another, and finding it is the quickest way to tighter groups.Never pump beyond the maximum the manufacturer lists, store the gun with one pump in it if the manual says so to protect the seals, and add a drop of pellgunoil or the recommended oil to the pump pivot point now and then.What You Will Want With ItEye protection for the shooter and anyone nearbyA pellet or BB trap rated for the gun's power, or a safe backstopPaper targets or reactive targetsA case or sling for transportSafety and Local LawsTreat every airgun as if it were loaded, keep the muzzle pointed in a safe direction, and keep your finger off the trigger until you're ready to shoot.
