if "energy arriving at the target" is a consideration at all, then ANY of the whisper cartidges is the wrong answer. and 6.5's have plenty enough bullet selection for something like that. 6.5-284, 264 win mag, 6.5-06, 6.5x55 have all won their fair share of long range matches, so even hinting that there are not bullets suited to this cartridge is preposterous. if i wanted lots of energy, i would shoot the .35-375 Ruger and 280 A-frames and call it good, the whole point is to make it a "toy"
