re: Sighting in a bow

IMO.... if you are only changing the draw weight 3 to 5 lbs, this will only change the arrow point of impact a very small amount out to about 25 yards. Beyond that, you might need to make slight adjustment to your pins.

A 10+ lb change, will require you to sight in your bow. Also, you should probably check your arrow flight by checking the "paper tunning".
