This is a stupid question. But i noticed one day when i was shooting my 223 that if i set the scope at a diffrent power i would hit diffrent. Now nothing drastic. but if i would go from say 9 power to 16 at the same range. my bullet impact would change. Had a guy tell me the same thing the other day. I was just wondering if someone could tell me why this is. Maybe im just messed up, i don't no. Any information would be great thanks.
