What would be another .30 rifle that is accurate and somewhat lighter than the model 1917 Springfield?
There was no Model 1917 Springfield. There was the Model 1903 Springfield (WWI), the Enfield Model 1917 (WWI), and the Browning Automatic Rifle Model 1917. The Model 1903-A3 Springfield was used in WWII, as were the M1 Garand, the M1 Carbine, the M1941 Johnson, and the BAR Model 1919. Besides the US rifles, there were the European rifles: Gewehr Standard Modell 1898 (WWI)- Imperial Germany; Rifle, short magazine, Lee-Enfield aka SMLE (WWI & WWII)- England and all Commonwealth nations; Model 1889 Lebel (WWI)- France; Mannlicher 1895 (WWI)- Austro-Hungarian Empire; M1891 Mannlicher-Carcano (WWI)- Italy, and the 1891 Mosin-Nagant (WWI)- Imperial Russia. And don’t forget the non-combatant and neutral nations: Switzerland, Spain, Denmark, Norway, Sweden, Greece, Montenegro, Abania, and so on. Then the WWII rifles, the South American rifles, the African rifles, the Asian rifles . . . anyway, you get the idea, there are a lot of rifles to choose from.
