"Rifles and Ammunition and Rifle Shooting" 1915
http://books.google.com/books?id=kd_NAA ... t&resnum=1The above contains information on experiments on the .303 ammunition by J H Hardcastle, who designed the "Swift Bullet" for Kynoch and how that bullet was later developed into the Mk VII .303 bullet.
Some technical information on the bullets and military ammunition used by other powers of the period.
PS
According to George L Herter
" To make sure their military bullets tumbled every time , the British took the "Velopex" hunting bullet designed by Leslie B Taylor who worked for the gunmaking firm of Westley Richards Ltd of Birmingham . This was a spitzer bullet with the nose of the bullet filled with wood or fibers or for that matter anything light in weight. The British Army decided to use aluminum in the nose of the bullet."
So the Mark VII bullet is a combining of the Hardcastle Swift Bullet with the Taylor Velopex lightweight nose plug.
Taylor may have designed his bullet following Hardcastle's work or perhaps by using the German spitzer as a basic form.
