In response to the wildly popular DuraSeal Varmint Spinners, Champion offers four DuraSeal shapes. It is constructed of a non-metal, self-sealing material that absorbs hundreds of rounds from even the largest varmint rifles and handguns and still keeps its shape. Weighing 80% less than metal targets these auto-resetting targets let bullets pass through with minimal damage - dramatically prolonging the life of the target.
