Airgun writer Tom Gaylord did some velocity testing of the Texan. See a chart of his findings in the supplementary images. The AirForce Texan delivers more power than any other production air rifle: .45-caliber bullets leave the muzzle at 1000 fps (up to 500+ ft-lbs. of energy). Load, cock, aim, squeeze and deliver jaw-dropping power. An entire world of hunting opportunities has just opened up to you!
