This is an interesting topic. I have shot all sorts of different game animals on public and private, and each definitely has its own pros and cons. My favorite hunt of all time was my mountain goat hunt, as it was all on hundreds of thousands of acres of public land. The massive amount of public land and relative lack of hunting pressure made for a great hunt. My private land experiences have also been good, and I have been lucky enough to have friends and family who have allowed me to hunt their places. Or, I have obtained permission back in the "good ol days" by knocking on doors.
Elk and Deer are different critters, and quite simply, seem to prefer agriculture when available. Since the whole corner crossing court case, and the widespread use of OnX, my own anecdotal experience is this:
If you are the first person to discover the landlocked piece of property, the hunting will probably be good. Then when you kill one and you tell your buddy you need help, that seems to trigger a steady onslaught of pressure that eventually clears the entire section of most game animals. The animals that once inhabited the landlocked piece of ground eventually just go to...private property. Then you are kind of right back to where you started. I have watched this transpire over the years on a property I have hunted for nearly 25 years. To be clear, I really have nothing against the folks who are going in there. Good on ya if you want to put in the effort and burn some boot leather. And truthfully alot of the time they just end up pushing the critters onto the property I can hunt anyways. Or, they go on the neighbor's place that is a full no-go zone. Montana is unique as well, as we have some type of hunting season that lasts for 12 weeks. Even longer if there is a shoulder season. I think that most ungulates will only tolerate so much pressure before they leave the countryside altogether. I am sure experiences will vary by area and type of terrain, but I have heard similar stories from folks on both sides of the fence (pun intended).
