I once played with a short action, custom barreled 6.5/284 that I had set up just for the 120/125gr bullets. It was a lightning bolt killer! Flat shooting, shocking results. I shot 2 antelope doe right at 300yds ( I was sighted +1" high at 100yds, just pointed and shot) in Utah and exotics in Texas ( Fallow deer, Axis, and Blackbuck antelope) I settled on the Nosler 120BT. I would shoot a bull elk with that combo! I "suppose" the 140s are good, just never used them nor saw the need, just my .03. I was pushing the 120NBT to 3200 in that rifle.
