The major problem with the .303 Ross was the very poor ammunition that the English made. They were chambered for in spec ammo and that was one thing they did not get in WWI. They were also not as able to take the dirt but still it was mostly an ammo problem.
The English chambers in .303 are rather large to take ammo that is out of spec and at least go bang.
