[2] Dillinger was a black bull with a white face and underbelly and had a single, upside down, medium-sized right-side horn.

Although larger than most elite bulls of his era,[4] he was well known for his speed and agility, bucking over 86% of riders in 51 career outs at all levels.

[5] Herrington Cattle Company purchased Dillinger from stock contractor Neal Gay after he was awarded the title of 1999 Co-Bull of the PBR World Finals, along with Terry Williams' bull, the 1999 PBR World Champion, Promise Land.

And Neal, which is far from usual in this business, gave them a guarantee: "If they weren't happy with him after three events they could return him and get their money back".

Out of the chute, Dillinger took two long jumps and, according to Herrington, "it looked like he went halfway across the Thomas & Mack Center before he turned back, but it just happened so quick and so strong you're like, I don't know.

[3][9] However, in November 2021, José Vitor Leme rode Woopaa for the new highest marked ride in PBR history.

These rides include the following: At the 2000 Tuff Hedeman Championship Challenge in Fort Worth, Texas, future two-time PBR World Champion Chris Shivers rode Dillinger for 96 points in the Mossy Oak Shootout and won $5,000; at the 2002 Tuff Hedeman Championship Challenge in Fort Worth, Texas, two-time PRCA World Champion bull rider Jim Sharp rode Dillinger for 95.5 points in the Mossy Oak Shootout and won $85,000 for that ride;[11] 2002 PBR World Champion Ednei Caminhas drew Dillinger four times and successfully rode him all four times, with three scores of 94 or better;[7] 95 points for Ednei Caminhas in 2001 in Columbus, Georgia; the year before, 94.5 points for Caminhas at the 2000 PBR World Finals;[3] and last is when Corey Navarre rode him for 94.5 points at the 2001 PBR World Finals.

"[7] Dillinger was forced into retirement after "sustaining multiple fractures in his left hock that caused joint dislocation" at the 2002 Jack Daniel's Invitational Bud Light Cup Series event in Louisville, Kentucky, which occurred when his left leg was caught in the chute.

He was on track to win his third consecutive World Champion Bull title in 2002 prior to the injury.

[14][15] "We say we've never had a back-to-back champion, but that is only in the human category," said PBR Founder and Livestock Director Cody Lambert.

Dillinger won two years in a row, and he was battling with Little Yellow Jacket, Blueberry Wine, and Mossy Oak Mudslinger when injury took him out of the game.

[15] It is claimed that PBR great late bull Mick E. Mouse, who finished his short career undefeated, was his grandson.
