Hello I need the opinions/ advice of my fellow shooters on some steel targets I make. They were designed for use with rimfire and pistol rounds, we've tested them with everything up to .45 auto at 30 yards and they work awesome, zero damage as result. They are constructed of 12560 armor plate steel. ( same steel used in the military's armored vehicles/ tanks.) Simply put, they work great and last a long time. I'm just curious what you guys/ gals think of em. You can check out our website for a bunch of pics and further info. Any and all, good or bad opinions are appreciated, Thanks. www.jumpinjacktarget.com
