Mount it on a wood frame and cover with newsprint. Your local paper will have end runs of news print they will sell you cheap as they don't let a roll run out before they replace it with a big new one.
Zero you rifle for POA/POI at 300 yards on a different target.
Place new target about 6 feet from bottom of 2x8 panel.
Starting at 100 yards shoot 3 shots, move back to 200 and fire 3 shots, same for 300, 400, 500 and 600 yards.
Measure the distance from center of target to each shot hole high and low and record them and type out your average rise or fall on a 1 1/2X 3" peel and stick lable. Put on your buttstock and cover with clear packaging tape.
Now you absolutely know what a given ammo will do at all the ranges you will probably need.
If you change ammo, repeat. When you buy new ammo get the same brand,bullet weight and lot number on all boxes.
This keeps your scope with same setting as continually changing an internal adjustment scope is not recommended. Also when you get towards the limits of your scope adjustment internally you lose the amount of windage you can put on the scope.
Bottom line shoot, record, and never move your scope once zero is set unless you change ammo.
For instance if you zero at 300 yards your hold unders at 100, 200 are going to be about 6" for each. At 400 hold about a foot over and so on.
Even better get a Burris Ballistiplex scope and you have multiple cross hairs and you zero at 300 and determine where each cross hair is pointed.
Even more interesting save you gallon plastic milk jugs, fill with water and shoot them at each range and if possible have someone under cover down range recording bullets hitting the jugs and then photograph the jugs to determine how much remaining energy you have ate each yard line. You will quickly learn bullets give decreased terminal damage as range increases.
