I've kind of given up on Hill's Deer and Long Range. Unless you can get up west of RC and almost over the WY border its kind of hard to find a place to hunt that isn't crowded. Ended up going North and onto Private rather than Public land to hunt as it is a lot more open and the deer don't resemble Lassie.
Those Hill's Deer are a bit small for anything large in caliber as their smaller than an Antelope.
If you have the time to do it and the means to do it there are a lot of places on the Grass Lands that you can shoot long distances and on some pretty decently sized Mule deer.
If you want a huge Whitetail then head over east and south down along the Missouri river and you can run across some pretty huge one in certain area's.
Either way its all fun and have a good time.
