Dover Cliffs bullet found...?

More than likely fired from a Lee Enfield From WW2 cant be 100% but i use to find hundreds of them when i was a kid all along the south coast plus 9mm cases, 303 case. Dates back to the war when the squaddies were training. Further along the coast towards the solent there are millions of them lying about. There are old ranges from WW2 all along the coast (some were temp and no longer visible), I also dug up a few live anti air craft rounds from WW2 in my garden when i was a nipper which pleased my mum.
