If you will pardon the diversion I have a tale to tell.
I grew up in Nashville TN because my Dad was a professor of nuclear and theoretical physics at Vanderbilt University. As a child he was always inviting students, visiting dignitaries, and fellow professors home to dinner. The children were always included in the events all the way up to bed time. It was a wonderful time and we met people from all over the world (including professors from Russia during the Cold War).
The one gentleman I remember quite clearly was a newly hired professor to the math department who came over from merry old England. During dinner, my father asked him of his life and his education. It turns out that his first trip abroad was to France in his sixteenth year and that was to an event called The Battle of Dunkirk. No, he did not carry an Enfield, but a large shoulder fired WW1 recoilless anti-tank weapon that he described as more heavy than useful. He said the Sergeant Major chose him and several other scrawny fellows from the ranks to act as rear guard because the little guys knew how to get their asses whooped and get back on their feet again. He said the big guys were just learning. He didn't tell us much more about his life in the military, at least not while the children were present.
This is what he told us about the Enfield in 303 British. After the war, he applied for work with the government to help him pay his way through college. The government of Great Britain gave him a job as an animal control specialist in the African Colonies, Kenya or Nigeria, I can't remember. So every summer he would go to Africa for three or four months to control the local fauna. This entertained everyone at the table. I remember my Dad asking him what was the largest animal he ever had to control. He responded that on several occasions he had to deal with enraged elephants that were passionately squashing the local citizenry. My dad asked him what rifle he was using to dispatch the wild elephants, expecting to hear of some such round as a 375 H&H or 416 Rigby. Instead he responded that he was issued an ancient #1MK3 Enfield in 303 British.
My Dad looked at him aghast and asked him if you could actually kill an elephant with a 303 British.
"Yes", the gentleman responded in a very calm british way, "If you get close enough".
True story.
