I am a novice when it comes to shooting distances and especially using scopes. I mostly sight a scope in for 175 yards and hold over or under depending on where the coyote may be. My question is..... If you sight in a scope at 100 yards zero with the scope on 3x, will the point of impact change if you take a 100 yard shot with your scope on 9x? This is of course if all variables are the same as when the gun was sighted at 100 yds.
