In 1972, Barmby sold his second rodeo string, including Oscar, to Rodeo Stock Contractors (Bob Cook, Jack Roddy, Jack Sparrowk) out of
Clements, California. This was Barmby's final sale of bucking stock, prior to retiring as a stock contractor. Oscar bucked in the PRCA for his entire career, which began with Rodeo Stock Contractors (RSC), shortly after they bought him. For the first five years that RSC bucked Oscar, over 100 bull riders tried and failed to make a qualified ride on him. To incentivize the riders, RSC offered a bronze "Oscar" to the first rider to make 8 seconds on him. Also in 1975, Randy Mager obtained one of his two rides from Oscar at the
National Finals Rodeo when he finished as the Reserve World Champion. Even after these rides, Oscar still was ridden very infrequently. In 1977, Oscar's highest scored ride in his career came at the
Grand National Rodeo in
San Francisco, California, at the
Cow Palace, when Don Gay rode him for 97 points, just three points short of a perfect score. The score was a record in the PRCA for any livestock ride (
horse or bull) at the time. The ride also won Gay the bull riding event and the bull riding world championship that year. Gay, an eight-time World Bull Riding Champion, ultimately managed to get three qualified rides on Oscar during the bull's career. Some of the few other bull riders that got a qualified ride on Oscar include Randy Magers, Jerome Robinson, Allan Jordan, and Guy Barth. Magers and Jordan each got qualified rides twice from Oscar. There is some conflict in the accounting of qualified rides; the ProRodeo Hall of Fame counts 10 qualified rides. Ultimately, only eight qualified rides are accounted in Oscar's career in the 300+ attempts taken. In 1978, Allan Jordan, a future prominent judge for several bull riding circuits including the PRCA,
Professional Bull Riders, and
American Bucking Bull, Inc., won a challenge with the bull. He marked a high score of 96 on Oscar. It was not uncommon in those days for bull riders to fill in as judges and vice versa. "He was just so fast," remembers Jordan. "He was small enough that you could lose him." ==Retirement and honors==
