Safari-
Sorry, I missed the "1500 yd affair" or whatever it was and can't imagine shooting at game that far either with a hand held weapon.
While I hesitated to post the experience I did just because I didn't want to make people think that's my regular MO, I don't think a ~ 500 yd. shot at a calm, stationary and broadside animal with a large heart-lung target by a practiced rifleman with a good rest is an unethical shot nor a particularly difficult one.
