The .9mm-.30-.06 Steel Round Up has six targets ready to take on all of your favorite pistols, varmint and trophy buck calibers. These heavy-duty targets are carefully heat treated to an impressive rockwell hardness to give you unmatched shooting options. The adjustable spring loaded technology really comes in handy here, giving you the ability to go side by side with your pistol-toting challenger, or zeroing in on the real life pop-up, known as the prairie dog.
