I don't know if that was just a sarcastic comeback or whether you're now admitting that just maybe we are correct! When you rezeroed the gun at the 100 yard range did you then go in closer and shoot to see where the gun is shooting at 25 yards? If you didn't, I would suggest you do so and I think you're going to have a big surprise. You really do need to start over and find out what is going on because you really stand to miss, or even worse, to wound an animal at certain distances if that setup is as screwed up as it sounds!
