WW2 Firearms trivia question

[Greybeard]

Hello Red Devil,

Ahh - very good..

The P-17 was a license built version of the Enfield P14. The P14 was chambered in 303 while the P17 used the US 30-06. The P14 saw limited service with the UK as it held fewer rounds, and was a little slower in operation than the famed SMLE. The P17 was less complex than the Springfield, and thus cheaper to make, delivered the same rate of fire. For those of us that saw Gary Cooper as 'Sgt York', the movie was inaccurate in that Mr Cooper was shown using a 1903 Springfield Rifle, where Sgt York accomplished his feat using the Enfield P17.

OK- next question..

In the 1890's the US developed the first smokeless military cartridge, and a bolt-action rifle for standard issue to the US army. One particular event ultimately resulted in this rifle being replaced by a newer design after a very short service history. Can you identify the event, the rifle, and what replaced it in US army service?
