Our overall guidelines for the minimum, safe shooting distances are 15 yards for pistol and 100 yards for rifle. 3/8” thick plates can handle projectiles hitting at under 2,700 fps up to .30-06. If you’re careful and increase distance considerably, higher calibers can be used. Different weight bullets carry more or less energy at different speeds. We recommend spot-checking your plates when trying different calibers or distances. If the bullet leaves a small mark or nick, increase your distance from the target to reduce wear on your plate. Buckeye Targets takes no responsibility for damages done and/or harm to anyone. Use this product at your own risk.
