As has already been mentioned in an earlier post, the M1917 Enfield equipped 75% of our troops in WW1 because production at the Springfield and Rock Island government plants were woefully slow. Remington, on the other hand, could crank them out three times as fast, and was already set up to produce them, having just completed a contract for England of Endfield M1914's. Caliber change from .303 to .30-06 was a snap. And, yes, the Army bought 20,000 Ross rifles from Canada for training to free up service rifles to equip troops headed for overseas. I have a U.S. stamped Ross and it is so cool to shoot.
