In a mild defense of Weatherby: Back in the 1950s or thereabouts, Roy did an African trip. One of his toys was a .257 Wby. He shot an eland and for whatever reason hit it crosswise through the hams. From the photo, the exit wound was conical, maybe six inches across. Dropped at the shot, of course, with both rear legs out of action. Rapid bleed-out, probably from the femoral artery. IOW, that ad wasn't all that far off the mark.
