If you're only 1/4" off at 25 yards that could end up 1 inch at 100 yards. Could be 2 inches at 200 yards. If I were you I'd shoot to at least 100 yards to make sure. On my .270 I sight it in 2" high at 100 yards. It's about 1/2" high at 200 yards and about 6" low at 300 yards. From there it starts dropping real fast but I know this for a fact because I've shot at each distance. It's the only way to be absolutely positive.
