Rolling Thunder CORE Brute XL Cutdown Duck Hunting Call, Frost - #DC013-CF The Rolling Thunder CORE Brute XL Cutdown Duck Call is designed for duck hunters who demand more power and control in their calls. As the name implies, the Brute XL is a larger, more robust call than its predecessors, featuring a 3¼" barrel size reminiscent of classic P.S. Olt cutdowns. Built with a bigger exhaust, a longer tone board, and the unique step-bore system, this call offers greater precision in sound and tone control, allowing experienced callers to achieve the full range of raspy duck sounds. Unlike other models, the Brute XL requires more airflow to get the reed moving, making it perfect for hunters who can push heavy air pressure through the call. This call is not just forgiving; it invites you to lean into it and push its capabilities to the limit. Features:Extra-large design for powerful sound3¼" barrel size, similar to vintage P.S.
