Another vote for having to have the red reticle, and absolutely yes to the OP. The bull I killed last fall was over 200 feet below me across a drainage. The difference in dialing was significant, even for a shorter shot. On a map the distance measured 398 yards, but my Sig gave me an EHR reading of 312. That was a 6 click difference for my 280 AI, or about 13" of drop. Hit him 4 times out of 4 shots. If my range finder had not been angle compensating I'm pretty sure all 4 shots would have missed high, or a couple may have spined him.
