I was comparing the 140gr mrx to the 140gr ballistic tip.Both produce 3500fps in my rifles,with no pressure signs at all.Looking at my notes,the difference in point of impact at 400 yards was actually about 1-1/2".In my 300ultramags,the 180gr tsx averaged the same accuracy at 400 yards as the 180gr ballistic tip,but the difference in point of impact was around 2".The poly point of the mrx helps over the hollow point of the tsx,but the grooves still result in a lower BC.
