The swingers and frame are made of durable high-carbon steel to provide endless shooting fun. There are no welds in the swinger to break when impacted. Use only lead-nosed bullets and always wear eye and ear protection. This target is designed for use with the 45 ACP and 44 Special only. Use of other calibers may result in damage to the target and will void any warranty.
