Sometimes it didn't even need to chamber the .303 Round. The Brits obtained a bunch of 6.5mm Arisakas that mostly went to the navy though a good many ended up with T.E. Lawrence in Arabia. The Royal Navy also got some Winchester 44-40s and quickly found out they were as useless as a military rifle as you could imagine.
Heck, a good many American rear echelon troops in France were armed with Krags.
