The in-form marksman already has six to his name after only three games, grabbing two in the opening-day win over Scunthorpe, another in the draw at Blackpool and a hat-trick at Plymouth in midweek.
Chopra's goals have helped the Bluebirds to the top of the Championship table but the Newcastle-born 25-year-old is not prepared to rest on his laurels and has set himself an ambitious aim.
"I know I have to look after myself because I know if I'm fully fit then I'll score goals," said Chopra in the South Wales Echo. "I've set myself a massive target of 30 goals this season and I'm confident I can do that.
"I remember when I first came to the club and set myself 20 I finally got 22 and that was when I went through a period around Christmas when I didn't score for 12 to 14 games. Now I feel if I can get around the 15 to 20 mark by January-February I'll be right on the mark to get my target of 30."
He added: "If I got that number of goals you would really like to think that would be enough to get this club up to the next division."
