I have hunted in Unit 16......
Depending on where you have been used to hunting, be darn sure that you have the best cold weather clothes that Cabela's has to offer.
Our shots range from 10' to a little over 300 yards and you should be very proficient at 300 yards with your rifle.
What is very wierd about the Kansas bucks is that many of them have broken racks. Some deer will only have half a rack, while MANY will have broken tines. There are tons of large bucks in Kansas, and it will be obvious that they fight a lot. Fighting bucks mean broken racks.
Since you are probably hoping to have a trophy deer, I suggest that you have enough glass on your rifle to where you could easily tell if a buck has a damaged rack at 400 yards.
I hunt with two rifles in Kansas, a 7 STW with a 8-32 on it, and a 7 Mag with a 6-24 on it. My brother hunts with a 7 Mag with a 4-16 Bushnell 4200, but he does not care about racks. He has spent good money shooting deer with busted racks that were a waste of money.
Very, very few people hunt out of a 15' ladder stand in Kansas, and if you do carry a ladder stand, it is worth it's weight in gold.
Be sure to carry a grunt call and a rattle bag. I called in a lot of deer on my last Kansas hunt.
I use a product called Forget the Wind, and I have never had a deer smell me. In fact, on my last hunt in Kansas, I had a doe bed down at the base of my ladder stand with my back pack laying right next to her. I also had two bucks fighting 10 yards in front of me, along with 10-12 does that had come to watch the freekus, none of them ever smelled me. By spraying Forget the Wind on my feet, the deer never smelled the trail that I walked in on.
A good set of binoculars is a great idea, but not a substitute for high powered glass on your rifle. Remember that you can tell anything about a deer's rack with a 3-9. Bucks are often chasing does, and you often will only have a couple of seconds to make a decision to shoot or not to shoot. When the bucks are running broadside, you really have to some pretty good glass to see the "off side" beams.
I used up a bunch of those hand warmers with the chemicals in the bag. I put one in each boot, and laced two under each boot strings, set with one on each hip, and had them in both pockets. When the temp gets to 6* with a breeze, you had better prepare for the cold. We saw around 90-100 deer per day sitting in the ladder stands.
Try to find two very imortant people before you get there, a taxidermist and a meat processor. If there is no meat processor, then you are going to have to process the deer yourself, make preparations: knives, saws, plastic bags, coolers, etc.
