RE: Odds of success
My thoughts: the numbers are probably pretty accurate. Most hunters do not have the dedication necessary to get an elk in tough years, such as when the snows come later and the migration doesn't happen until after rifle season. Antelope are easy to shoot because they are so easy to spot and there are so many of them. Deer can be easy or hard, depending on where you're hunting them, so it makes sense the success ratio would be closer to the middle.
