Bullet identification

I found about a dozen of these bullets whilst I was metal detecting a dried out lake on the grounds of a large house that was used as a military hospital during world war 1.
I was wondering if anyone on your forum could identify them for me. Are they from the great war or are they modern? What type of gun would have fired them, maybe a pistol of some sort? I have posted some photographs and will give you some dimensions.

Kind regards,
Danny Jones

Bullet size .450
Casing diameter.475
Overall length.1.250
Lip length (head stamp end) .530
Casing length .750
All sizes are appropriate but measured with a verbier caliper

Just seen the Photo…delete all reference to.303 cartridge…
Revolver cartridge Cal .455 Mark II Cordite, for Webley Revolvers and later Colt and S&W WW I revolvers.
Headstamp same origin, and easily confused for .303 of same period.
