Friends: Today I purchased ten boxes of Federal American Eagle .38 Sp 130 gr. 'ball" ammunition (AE38K), which I intend to use for informal target shooting. I am surprised to see that the box labels cite a velocity of 950 fps and a muzzle energy of 260 ft.-lb. for this load. Could those be the real numbers if this ammo is fired from a 4" or 6" barrel? I ask because most +P 125 jhp .38s seem hard pressed to get 950 from a 4" barrel, while this is supposedly a standard pressure loading. Thanks for your feedback. --c
