Yeah, you have to get the scope really low to get around 4". Most mounts and scopes won't get there anymore.
One shorter-range sight-in that does work fairly well is an inch high at 50. This is a LOT better than dead-on at 25, and if the scope isn't too high, or the cartridge too fast, it will work out to 200-250. But it's a lot better to shoot the dang rifle at longer ranges if that's what you might do in the field!
I once knew a Montana rancher/outfitter who insisted all his new clients sight-in at 25 when they got to the ranch. A lot of them missed, of course, especially the guys who came from further east and had "see-through" scope mounts on their deer rifles. The rancher has an old Remington 721 .270 with a K2.5 Weaver mounted really low, and it worked with his rifle, but not many others. But like a lot of people who have limited experience, he assumed it worked for all rifles, all the time....
