John...sounds like you have a plan, using your equipment before the hunt. You`ve also dialed. I also assume you worked with a spotter? Practice with what you already know. Very easy to build a ballistic drop tape and attach to your scope turret. Easy to dial. I hunt with my son, he and I spot and range for one another when one of us is shooting. If you`re going to be hunting with an outfitter or partner, have them range, you concentrate on the shot.
I burned up most of 100 bullets before my hunt this fall, shooting in different weather conditions and distances so I wouldn`t have to sit and think of what to do when I had a chance at the animal I wanted.

Good luck
