Is there a definitive answer as to whether he was using a 1917 or 1903? I've heard that, statistically, the 17 is much more likely. However, I've also heard the argument that he didn't like the peep sights of the 17, and sought out an 03. Is there any way to know for sure?
(does it really matter? Well...maybe to gun geeks )
A gun geek like York may have realized (or maybe it didn't matter to him) the longer sight radius of the 17 provided a little more consistency for longer shots, the peep diameter being a little larger and closer to the eye for dim light, the sights being better protected by robust ears with more repeatable settings would have been an asset. Not to mention one more for magazine capacity and 4 degree helical bolt lugs that close through an arc of twenty degrees to cam cut surfaces on the bolt lugs with opposing surfaces on the receiver of approximately 70 degrees of rotation increasing the locking power of the bolt on poorly made, dirty or damaged ammo. The Springfield bolt has to travel nearly 37 degrees I think before it begins to lock up on square mating surfaces.
He may have not liked the weak ejector spring, length of the bolt travel, additional weight or length or the sling that was more than likely issued with a 17 if in fact that's what he used. Or the tendency for the rear ladder to be shoved forward by his hat or helmet if it contacted it when shooting from position but he was probably to clever for that to happen.
