Here’s a target to help you zero your rifle.To zero your rifle, focus on getting a good group on this target, rather than getting all of the rounds into a square. Each small square is 1/4 inch, the corner red squares are 1″ and the center square is two inches.
Be sure to aim your rifle at the same location on the objective square each time you fire. The goal with zero is to get small target groups consistently. After doing that, adjust your sights or scope to move the group on the page. This target prints on 8.5″x11″ paper and will work just fine in either B&W or color.
