This is not a question of “When did you start hunting?”, but rather, when did you respond to the hunt, or hunting, in the way Robert Ruark described it in The Horn of the Hunter.
For me: most likely when I was pre school age.
I had toys of plastic animals, while all other kids where playing with toy cars.
I watched all african safari movies, and animal documentaries on TV. I dreamed of hunts.
I was begging my granpa (A hunter) to show me his guns on weekly basis when I was pre school age.
He thought me to shoot 22 as soon as I could hold the rifle.
I Shot my first roe buck at age of 17.
At the age of about 12 or earlier I asked my mom to buy me a book in a book stgore about hunting, guns, ballistics and hunting dogs, when I was at primary school.
I still have that book.
And within a year I knew it by heart.
My next big discovery was Africa, when I was at my 40-ies.
It was beyond my imagination till that time that African hunt was legal and possible in this age and time - the consequence of brain washing by discovery and national geographic channels.
Then, I went full in!
Hunting locally at my place, was already a routine.
Buying 375, wedlocked me in.
DG experience of Africa sealed my dreams.
