Fusion Ammo recently released a testosterone-filled video of former UFC heavyweight champion Brock Lesnar testing its ammunition on prairie dogs in South Dakota.

“I’m Brock Lesnar, and I’m back!” the 300-pound, Lesnar yells into the camera after shooting several rounds from the hip.

My motivation is there and I want to get on the map again.” users will recall our exclusive interview with Lesnar, in which he stated that hunting has been a lifelong passion. “I’ve made chasing bucks a big part of my life,” he told us.
