The British Army found that their 450 Martini Henry rifles were effective against their foes in many parts of the world. When the 303 cartridge came into use it proved much more effective than the slow heavy .45 bullet.
I do not know if the Martini-Henry rounds were just too slow compared with the 45-70 but the 303 certainly did prove to be superior.
