Other Springfield Models:
U.S. Rifle, Caliber .30 M1903A1:
In December of 1929 the stock design was changed from the straight stock to a pistol grip stock. The fore-end was also modified by removing the finger grooves. The buttplate
was checkered to give better support on the shoulder, and the trigger was modified with serrations to prevent slipping of the trigger finger.
U.S. Rifle Caliber .30 M1903A2:
The design of this rifle was not for firing from the shoulder but rather modified to attach to the cannon tube of a tank to be used for sub-caliber practice.

The bolt mechanism of this rifle was unique to the USA, though many war-surplus rifles were used elsewhere after 1945 and others were supplied through Military Aid programs into the 1960's.
Experience in the Spanish American War showed that Spanish Mausers were superior to the Krag Jorgenson. Convening a board of officers at Springfield, testing began on the 1901
rifle. Using the best attributes of the Mauser and the Jorgensen the 1901 experimental rifle was developed.
For reasons which seemed right at the time, the US Army had adopted the Krag-Jorgenson rifle in 1892, but within a very short period the Krag's limitations were known and the Ordnance Dept. had to begin looking into a replacement. After thinking what designs available at the time, together with some painful lessons from the Spanish-American war where the 7mm Mausers. The Ordnance Dept. decided that the Mauser system had the most to offer and entered into agreements with Mauser to build a modified Mauser rifle under license in the USA.
In its original design, the rifle was built around a blunt nosed bullet rimmed, known as the .30" M1900, based upon the Krag-Jorgenson rifle cartridge. This bullet was disposed of in a
short time when it became obvious that the Mauser magazine did not respond well to rimmed cartridges, and the rimless .30" M1903 still using a Krag bullet. After more trials the case was
lengthened from 60 to 63mm and a new blunt bullet was developed, the result being the .30" M1903 round and this became the first service issue cartridge. However Germany developed the pointed or "spitzer bullet and the M1903 round was rapidly converted, by developing a suitable pointed bullet, into the .230 M1906. This cartridge and the millions of rifles chambered for it came to be called the .30-06. This new cartridge was developed, some 150,000 M1903 rifles had been issued and all were called back and re-chambered for the new round.
