if i'm not mistaken you should have the rifle zeroed to hit one and a half inches high at 100 yards. you can go to winchester's web sight and use thier ballistic chart to get the best info on the particular round you plan to use.

Shoot a few rounds at 100 yards also. Zeroing at 25 yards pretty much helps you hit the paper at 100 yards. There is will likely still need to be some fine tuning of windage and elevation to be completely zeroed.

You need to shoot at actual distance for your desired zero. I would personally set up for 200 yds. Dead on at 200 with a commercial 130 grain load you will be able to hold dead on out to there, and even at 300 only be about 5-6 inches low. With variances in firearm, ammunition, and shooter, you need to prove actual results.

You can interpolate a 25yd shot at so many inches high to estimate what a gun will do, at say 100yds, but until you punch consistent holes at your desired zero range, you are rolling the dice. I personally want to come as close as humanly possible to guaranteeing where my sent rounds are going to hit. I want to be able to put that shot on that animal and make a clean, quick kill.
