Well I don't know why some of you guys are knocking down the NBTs. My 270 win with 55 gr of IMR4350 and 130 gr NBT has accounted for a least 30 deer. All but 2 dropped where they stood. And one of these was a mulie buck at over 400 yds - and he only went about 50 yds before piling up. The other was a whitetail buck that needed a second finishing shot. So as for the NBTs I have no complaints.
But back to the original post; yes, the 140 gr would be a good choice.
