Outside of the National Grasslands units like 87 and 88 that take about 8 or 9 poins as a resident to draw, there aren't many other options. The Big Game Walk In Access Areas are supposed to address this, but they are totally overrun and don't have that many antelope on them.
I think it's pretty much bad for all methods of take. I have some pirvate land I can hunt, and while he lets alot of people hunt it, he also does let walk ons hunt. He has alot of land and he also has a lot of antelope on them but with the few of us that hunt it we have more than enough room to not pressure each other too much.
I have hunted the WIA on many occasions, and on many ranches.
Rifle season? ---CRAZY! Stay away is my best suggestion. ...and the animals have long since booked it to private somewhere.
I hunted several ranches during two seasons in archery, one year for 18 days, and one year for 3...I saw a total of  other hunter on any of the ranches durign those 21 days...and I would estimate the one time I went rifle, I likely saw 21 hunters on each ranch on the  I hunted them! I gave up and looked for some private to hunt the next two days, with no luck, I got the feeling that the farmer/ranchers were already fed up with requests and the hunters making a mess of things.
When I went archery hunting the first time...I had ranchers driving me around and pointing the animals out to me, or giving directions, letting me use different gates, etc....WAY cool about it.
As a Taxidermist I look at hundreds of Whitetail Bucks every year. I know that I have seen many different ways people judge the size of racks on live deer. I think for the most part they all are pretty close. I'm going to give you some measurements that I have noticed being right on in just about every deer. We have used it in the last couple years and have only been off by about 5-6 inches. We do study the deer while bowhunting so we get a little more time to look at them....
