How much is a little high at 100? 4", 6"? You may want it a little high at 100 yards as that round will drop like a rock beyond that. What most people don't realize is a little high at 100 makes for much much less drop at say 300. For example a .30-06 sighting in at 100 yards is dropping over a foot at 300 yards. Sighted in at 300 yards however it's only 4" high at 100 yards.
So even at 6" high your probably still hitting low at 200 yards with that rifle, but it's still packing enough lead to be very lethal at that range.
