Before I posted this, I researched this :-) There is no way I could honestly say Major Rathore, the silver medalist in double trap shooting from 2004 Olympics and possibly Ronjan Sodhi, gold medalist in the world cup look promising for a medal. And the reason is that I had no clue what double trap meant.
Thanks to wiki and google, I now know the answer and and just fyi, apparently 2 targets are released simulantenously in different directions at different speeds from traps and the shooter has to hit them. The scores in different rounds are tallied. That lead to my next worry about the targets, whether any "live" thing was used, but it looks like they use clay pigeons. However these don't resemble pigeons, but they look like discs - so I am still wondering about the need to call them "clay pigeons".
Anyway it looks like India shooting team does well in other categories as well (no I don't understand the categories or the ammunition). As an added twist, Ronjan Sodhi is scrambling for a wild card pass despite winning the world cup gold.
Chance of a medal?
