Gerry,
I added 150 fps to the 120 grain NBT over the 140 grain load and the 140 grain load beat the 120 bullet by 2" in a 10mph wind.
the 120NBT had 5" less drop @ 500 though.
Exbal does not show Nikon's plex reticle, so I would need the subtension @ the correct magniifcation to give you accurate figures.
