Nothing is free these days... Wrong.
Crooked Bend has mashed together a compilation of some of the most intuitive and creative shooting targets that we could find. It is as easy as picking out your favorite designs, clicking the PDF icon to download it and then, print it out using your local printer. Boom, free paper targets to unload your favorite caliber firearm at. Well, technically, you have to pay for the paper and ink so it is not exactly free but whatever.
P.S. Your boss said that they would not mind if you used the company printer, just make sure to reload it with paper whenever you are finished. (Winky wink.)
