This is a silent film from the 1930s of a woman on safari in Africa. It's a great little trip back in time. To me, it looks like she's using a Haenel-Mannlicher. I'll bet it is in .275 Rigby (AKA 7X57 Mauser). WDM "Karamojo" Bell also used a .275 Rigby to kill elephants.
From the description of the video: Her kills include a cheetah shown at 4:04, a water buffalo at 4:40, a gazelle at 6:46, a male lion at 10:30, an elephant at 11:00, and a bull elephant at 11:44. At 14:04 a man walks by with a camel, followed by a caravan. At 14:30 the woman poses with children and an early Land Rover touring car. At 15:00 Mt. Kenya is visible.
Even though she never went on a Safari, this film reminds me of my Grandmother, born in 1900. I was told that she would hunt and fish more than my Grandfather.
This is a must-watch, motivational movie!
