I was musing recently on the Army's .30 caliber round of old, what we often call the .30-06, and especially its impact on shooting, so far as riflemen are concerned.
The Army adopted the Springfield bolt action rifle, the M-1903, in 1903, and the cartridge that was introduced for it, the .30 M1903 Springfield cartridge. After being in service for a brief period, the Army modified the cartridge slightly, though did not alter the chamber dimensions. The re-designed cartridge became known as the .30 M1906. The ".30-06" lasted only a short time with the Army, being replaced by the .30 M-1 and later by the .30 M-2. But the cartridge became know among civilian shooters as the .30-06, regardless of the bullet weight or type. So popular was the round that it was immediately set upon by wildcatters. Necking up or necking down the basic case gave us the .270 Winchester, the 7mm-06, and the .35 Whelan. Less known, it also spawned the .50 Caliber Browning Machine Gun (.50 BMG) round.
Sa What? I hear many of you exclaim.
The Army Ordnance thought the .30 M-2 cartridge so near to perfect, that the Ordnance simply drew up that round on a scale of 5:3 to develop the .50 round. So the same proportions are used for both rounds.
