These durable targets withstand hundreds of rounds while maintaining their shape. The 8" plate is an ideal backstop for use with the 8" Shoot·N·C® Bull's-eye Targets or other Birchwood Casey Adhesive Targets. Use any caliber from .22 up, at a distance greater than 30 yards. Hanging targets are not intend to act as spinning targets. Not for use with BBs, pellets, or air soft guns. Challenge yourself and have fun.
