Great rifle!!! My buddy has a 1917 manufacture. They kind of screwed up when it was manufactured. The barrel is .303 for the P14 and the chamber is .30-06 spec. He handloads for it. It is the only .303-06 I've ever seen. My old FFL sold it to a guy and he proply returned it claiming it was shot out. The rifling was very strong so I took a cast of the chamber and slugged the barrel. Sure enough, A 1917 w/ a 1914 barrel.
