The box states this gun delivers 700 fps. Airgun writer Tom Gaylord tested this gun for the Pyramyd AIR blog and got 755 fps when using extremly lightweight alloy (lead-free, 4.0 grains) pellets. If you use lightweight lead pellets (7.0 grains), your velocity will be around 560 to 580 fps. He found that Gamo Match pellets (7.56 grains) delivered the best accuracy when shooting the pistol from a rested position.
