Brandon McReynolds was born on October 11, 1935 in Midland, Texas. Brandon was raised on ranches in West Texas and started rodeoing in 1952 until 1974. Being from Texas, he started riding bulls and did not get on a saddle bronc until 1960 at the age of 24. He made himself a vow to get on ten saddle broncs, the tenth one was at Midland, and he soon joined the Professional Rodeo Cowboy Association.
In 1963, his first year in the PRCA, he went to the spring rodeos and won enough money to be in the standings. He was injured in May and August, which took him out of the standings for the rest of the year.
In 1965, Brandon started secretary work for Beutler and Sons which limited the number of rodeos he entered. Through his career, he usually made about fifty rodeos each year. In 1971, he was selected to secretary the National Finals Rodeo.
From 1965 to 1972, Brandon was in the top twenty-five bronc riders. In 1969, he qualified for the National Finals.
From 1960 to 1972 Brandon won over seventy rodeos including El Paso twice; Baton Rouge, LA; Burwell, NB; Oklahoma City; Raleigh, NC; Phillipsburg, KS four times; Coleman, three times, with eight first go round wins in a row; Mineral Wells three times; Longmont, CO two times; Ardmore, OK; Shreveport, LA; and Austin five times.
During his career he made qualified rides on some of the best horses of the time: Descent, Big John, Jake Rawhide, Jessie James, Cat Ballou, Angel Sings, My Fair Lady, Crazy One, Tom Dooley, Red Pepper, Knott In, Saucy Sorrel, Funeral Wagon, and Whiz Bang.
