Just shot a decent 8. My zero is at 100 yards with 140 BTHP Hornady black. That is what I shot it with. Buck jumped really high, getting all 4 off the ground and then immediately ran into the brush. That to me tells me it's a hit. Got down and saw no blood anywhere in the area where he was standing nor around. Aimed right where the head and neck connect. Gonna wait a few minutes more to make it a total of 35 minutes of wait time before I go into the brush looking. Distance is about 50 yards. Do you guys think elevation might be slightly off at 50 from a 100 yard zero? I also think my parallax adjustment may have been just slightly off. Any tips???
