Lloyd S,
From everything I can find, Remington-Eddystone Arsonal made the M1917 model (U.S. version of the P1914 Enfield in .303) chambered in U.S. 30-06 as did Winchester for U.S. Troops in WWI.
When they came out with the sporterized version as the Model 30A Bolt-Action Express Rifle as a modified M/1917 Enfield action.
Calibers were 25, 30, 35 Remington, 7mm Mauser, 30-06, 5-shot magazine. 22-inch bbl....$445
M30R carbine w/ 20-inch bbl......$475
M30S Sporting Rifle in 257 Roberts, 7mm Mauser, 30-06, 24-inch bbl.....$545
Can't seem to find much on military version.
