Would some of the "Experience" on the board offer your thoughts for maximum effective range for 140 gr accubonds out of 270 Win for whitetails? Is that determined primarily by bullet velocity, since there seems to be plenty of retained energy downrange? I read different opinions as to a minimim effective velocity for them. typically ranging from 1,800 fps to 2,000 fps, but some suggesting even higher. My load starts about 3,120 fps and is at about 1,950 fps at 650 yards. thanks in advance.
