Mr. Frazier. Yes, sir; that was at two targets. The first one I gave you—Killion fired in 9 seconds. The other was a target marked Cunningham and Frazier. Cunningham fired his three shots in 8 seconds and I fired my three shots in 5.9 seconds.
Mr. Eisenberg. Now also you had made certain calculations concerning what we have been calling the lead that had to be given to a target, assuming various factors which were supplied to you. Do you have those calculations now?
Mr. Frazier. Yes, sir; the lead would amount to shooting over the target at 175 feet, a distance of 6.7 inches, and the decimal on that figure is not an accurate decimal because this figure relates to an average velocity of ammunition of this type, and is concerned with a speed of a vehicle which is also estimated, and a distance which may or may not be exactly accurate.
But at a ground speed of 11 miles an hour, it would be necessary to shoot over or lead a target 6.7 inches for the bullet to hit the intended spot on the target. At 265 feet the lead would be .51 feet, or 6.1 inches.
I might say that the variation, that of less lead at the longer distance, is in great part due to the fact that the target is farther away and that the shot is more nearly in line with the direction in which the target is moving, which would account for much of the drop in the amount of lead.
And, in addition, I calculated this on the basis of the fact that there was a slight slope between the 175-foot and the 265-foot location downwards away from the shooter, which would also tend to more nearly cause the target to be moving in the same path as the bullet.
Mr. Eisenberg. And did you convert those lead distances into the amount of inches which the shooter would have to sight above the head, above the point of the target?
Mr. Frazier. Those figures I gave were the elevations or the sighting distances above the target. The 6.7 inches vertical lead or sighting over the target is the equivalent of leading on the ground of 1.4 feet.
Mr. Eisenberg. And that table also shows leads at other car speeds?
Mr. Frazier. This table—I could calculate them—it only shows miles per hour translated into feet per second.
