I have a 3-12 and used it to take an antelope buck last year at 550 yards and a decent 4x5 mule deer the year before at 287. The deer was moving and it was an offhand shot and the reticle seemed helpful. I dialed for the antelope and it worked perfectly. So far only 2 shots at game and 2 animals down. I really like my 3-12.

I've yet to try the 4-18. A local shop marked one 50% off on Black Friday and I really wanted it but I was out of town that day.
