In "The Book of the Garand", page 277, Maj. Gen. Hatcher states: "In the spring of 1948 ... U.S. Rifle, caliber .30, M1, No. 3,595,949 was fired for group with 1939 Frankford Arsenal M1 ammunition. The 10-shot gave an extreme spread of 14 inches at 200 yards. On June 8, 1948, this rifle was taken to Quantico by a party of Ordnance officers and engineers, and Master Sergeant McKinney worked over the rifle while the group watched. The rifle was then fired by two members of the party, and each one obtained 10-shot groups at 200 yards which gave an extreme spread of 6.75 inches, or less than half the previous group size."
