I have a RSM in 375 H&H. When I got it it shot
low at 50 yards. I replaced the front sight with a higher bead purchased from NEG. It came up some but still shoots 2.5 inches under my POA at 50 yards. In measurement how much higher of a bead do I need to get it right on. I do not want anymore trial & error. If anyone knows it would be much appreciated.

A taller front sight will lower your POI not raise it.

Thanks everyone, I knew which direction to go but forgot AGAIN. Very helpful.
