"We all know what happened at the last Asian Championship in 2008 where not one quota could be bagged. It cannot, should not and will not be repeated. I am keeping my fingers crossed," Thomas said.

Athens Olympic silver medalist Rajyavardhan Singh Rathore, former trap world champion Manavjit Singh Sandhu and former world No. 1 in 10m Air Rifle Anjali Bhagwat are yet to qualify for the Olympics and the championship will be the last opportunity for them to book their berth for the mega event.

Nine Indian shooters, including the likes of Olympic gold medallist Abhinav Bindra and double trap world number 2 Ronjan Sodhi, have already booked their berths for the marquee event.

The final selection for the mega event, though, wrests with the National Rifle Association of India (NRAI), who take into consideration the players' scores in competitions throughout 2011.

The association is expecting a good show with the performance of shotgun shooters at the recently concluded Asian Shotgun Championships adding to their aspirations.

"India has emerged as a powerhouse in world shooting. We have had two World Champions and two junior World Champions, Olympic medallists and multiple World Cup winners," said NRAI President Raninder Singh.

"We have won medals at all major international competitions. We expect great shooting from our team in Doha and expect the quota tally to go up to around 14," he said.

India swept the Shotgun Championships with Rathore, Mansher Singh and Man Singh clinching gold medals.

Rathore, in fact, equaled the world record of 148/150 in qualifying round and is a frontrunner to bag one of the two quotas on offer in double trap event.

"I am in relatively decent form for the last couple of months," Rathore said.

"I was in and out of the Indian team due to a variety of reasons. Such treatment is not conducive to a good preparation.

"Do any of my competitors around the world doubt my ability to win again? No. But will I compete in the Olympics? One chance to qualify is very slim, it can go any way and every shooter in the field knows that. I am training for the best but prepared for the worst," he added.

Meanwhile, world No. 2 Ronjan Sodhi is looking at the Asian Championship as an experimenting ground where he can fine tune his skills before the all important Olympics from July.

He has not competed in any event since becoming the first Indian to defend the World Cup title in October. However, he has been training in Italy almost on a non-stop basis with an eye on the London Games.

"I have already won the quota and this is the time for me to fine tune my shooting and experiment with my technique to ensure I peak at the Olympics," Sodhi said.

"Every competition is important and there is no better feeling than winning gold for India. I want to start the year well but more importantly I want to finish it on a high on the Olympic podium," he said.

The Indian team has been in Doha for the last two weeks to get acclimatised, a move Rathore says was the right one.
