[1][3] Gontcharov is also a member of the shooting team for Dynamo St. Petersburg, under head coach Anatoliy Suslov.

[1] Gontcharov qualified for the Russian squad in pistol shooting at the 2000 Summer Olympics in Sydney after shooting a mandatory minimum score of 590 in air pistol at the 1999 ISSF World Cup meet in the same Olympic venue.

[1] In the men's air pistol, Gontcharov scored 572 points to share the ninth position with neighboring Uzbekistan's Dilshod Mukhtarov in the prelims, nearly missing out the final round by a two-point deficit.

[4][5] Gontcharov gave himself a chance to improve his feat in the men's free pistol by occupying one of the top eight slots for the final round, but eventually fired a disastrous 7.3-point shot in the ninth series that dropped him out of the medal podium to fourth with a final score of 662.5, finishing just behind the bronze medalist Martin Tenk of the Czech Republic by a 0.3-point margin.

[6][7] At the 2014 ISSF World Shooting Championships in Granada, Spain, Gontcharov edged out China's Pu Qifeng by a tremendous 1.1-point advantage to claim his third career bronze medal (the first one being done in 2002 and the other in 2006) in the men's air pistol with 178.9 points.
