Mr. Nicol. There is a cannelure, that would be the position at which the projectile is crimped and held in the cartridge case.
Representative Ford. Why wouldn't that show on Q-1?
Mr. Nicol. It would be over here on the other side. You see you only see this much of Q-1, and it may show on Q-1, but it will be over underneath, and you only see this much of it—in half the field.
Representative Ford. This is an overlay in effect?
Mr. Nicol. In a sense, yes, and you are actually masking off half of each one that is represented over here, and masking off half of the K-1 over here.
(Discussion off the record.)
Mr. Eisenberg. What is the magnification of these photographs, by the way?
Mr. Nicol. These were taken on five by seven, I would estimate about 30 diameter.
Mr. Eisenberg. And is the magnification of Q-1 the same as the magnification of K-1?
Mr. Nicol. Yes, sir; the optics are carefully matched in order that they magnify identically.
