Mr. Eisenberg. How would you characterize the differences between the muzzle velocities of the various rounds in terms of whether that difference was a large or small difference?
Mr. Frazier. This is a difference well within the manufacturer's accepted standards of velocity variations. They permit in their standard ammunition manual, which is a guide to the entire industry in the United States, a 40-foot-per-second, plus or minus, variation shot to shot in the same ammunition.
Mr. Eisenberg. Have you calculated the muzzle energy of this 6.5 millimeter ammunition in this weapon?
Mr. Frazier. It was furnished by letter to the Commission. Yes, sir—the muzzle energy was calculated on the basis of the average velocity of 2,165 feet per second as 1,676 foot-pounds.
Mr. Eisenberg. This is a calculation rather than a measurement?
Mr. Frazier. Necessarily a calculation, because it is merely a term used to compare one bullet against another rather than for any practical purposes because—because of the bullet's extremely light weight.
The bullet's velocity and weight, and gravity enter into the determination of its energy in foot-pounds.
Mr. Eisenberg. Is the 6.5 millimeter Mannlicher-Carcano with which we are dealing an accurate type of ammunition as opposed to other types of military ammunition—as compared, I should say, with other types of military ammunition?
Mr. Frazier. I would say it is also accurate. As other types of ammunition the 6.5 millimeter cartridge or bullet is a very accurate bullet, and ammunition of this type as manufactured in the United States would give fairly reasonable accuracy. Other military cartridges may or may not give accurate results.
But the cartridge inherently is an accurate cartridge.
