Mr. Frazier. The bullet has parallel sides, with a round nose, is fully jacketed with a copper-alloy coating or metal jacket on the outside of a lead core. Its diameter is 6.65 millimeters. The length—possibly it would be better to put it in inches rather than millimeters. The diameter is .267 inches, and a length of 1.185, or approximately 1.2 inches.
Mr. McCloy. You say that the diameter is 6.65. Did you mean 6.65 or 6.5 millimeters?
Mr. Frazier. I was looking for that figure on that. It is about 6.6—6.65 millimeters.
The bullet, of course, will be a larger diameter than the bore of the weapon to accommodate the depths of the grooves in the barrel.
On the base of the bullet is a crimp ring, or a cannelure, which is located two-tenths of an inch from the base up the bullet and which is 6/100ths of an inch in width—that is, it is a band around the bullet 6/100ths of an inch wide.
I believe that is a description of the bullet.
Mr. Eisenberg. Have you tested Commission Exhibit 139 with the type of ammunition you have been looking at to determine the muzzle velocity of that type of ammunition in this weapon?
Mr. Frazier. Yes, sir. The tests were run to determine the muzzle velocity of this rifle, using this ammunition, at the Naval Research Laboratory in Washington, D.C., on December 2, 1963, using two different lots of ammunition—Lot No. 6,000 and Lot No. 6,003.
I might point out that there were four lots of ammunition manufactured by the Western Cartridge Co., only two of which are available.
Mr. Eisenberg. Can you give the results?
