You should be about .78" low at 25 yards for a 100 yard zero. According to the Remington ballistic calculator. The bullet has not had much time to rise up after leaving the barrel. At 50 yards you should be about .29" low, and at 75 yards about .02" low. That is figures for a 100 yard zero. Hope this helps. This was calculated with a 140 grain bullet. I can figure other weights if you want.
