In the 1936 Summer Olympics there were three shooting events:
25 meter rapid fire pistol
50 meter free pistol
50 meter free rifle
The next Olympiad, 1948, added a 300 meter rifle, 3 position.
The next, 1952, had the following events:
300 meter rifle, 3 position
50 meter rifle, prone
25 meter rapid fire pistol
50 meter free pistol
100 meter running target
Trap
That line-up would remain until 1968, when skeet was added except that the 100 meter running was dropped in 1960.
In 1972, the full line-up of shooting events was:
300 meter, rifle, 3 position
50 meter, free pistol
25 meter, pistol, rapid fire
50 meter, rifle, running target
50 meter, rifle, prone
50 meter, rifle, 3 position
trap
skeet
In Montreal, the 300 meter 3 position was dropped. This line-up remained until 1984 when the 10 meter, air rifle was introduced.
In 1996, the 10 meter, air pistol and double trap was introduced.
In 2000 the 50 meter running target was reduced to 10 meters and the rifle used was now an air gun.
In 2004 the running target event was dropped, and the number and type of shooting events has been the same since.
I would like to see the return of the 300 meter, 3 position and/or the 50 meter running target events.
The NRA 200/300/600 yard (or 200/300/500 meter) course would be interesting, but highly unlikely...
