Winchester® Ammunition Highlights 2023 ATA AIM & Grand American Trap Shoots

As the Official Ammunition of the Amateur Trapshooting Association (ATA), Winchester continues its commitment to one of the longest running shooting events in the world, the Grand American Championship.  

More than 10,000 competitive shooters and spectators from across the country will journey to Sparta, Illinois for the 2023 ATA AIM Youth Championship and Grand American World Championship, which runs July 27-August 12.  

“It’s the Super Bowl of trapshooting and Winchester has been a part of this historic event since 1899,” said Jason Gilbertson, director of marketing for Winchester Ammunition. “Winchester has once again teamed up with the Grand American shell house, bringing in truckloads of the world-famous AA® shotshell target load, the venerable Super-Target® target load and AA Diamond Grade® Elite Trap featuring 8% Antimony shot, which is suited specifically for long-yardage shooters.” 

The two-week “Grand Event” kicks off with the AIM Grand Championships, a youth shooting competition where kids from elementary school through college compete against others in their class in Singles, Doubles and Handicap Trap events. After the AIM event, individuals of all ages begin the 11-day Grand American Trap Shoot which consists of daily events like the Winchester AA® Class Singles. 

Team Winchester members Matt Bartholow, Foster Bartholow, Harlan Campbell, Keith Ditto and young phenom Dagen Voigtman will be battling thousands of talented shooters in their quest for more championship rings. The Bartholow Brothers will also be hosting their famous youth clinic on Sunday, July 30 by the ATA Grand Stands.  

For those participating in the event, please stop by the Winchester Ammunition booth on vendor row to check out branded merchandise, meet with Team Winchester members and staff, and to participate in exciting daily promotions.
