Most modern rifle cartridges will take you to 400 yards without the need for a knob. With a little bit of practice 500 shouldn't be a problem as well. All without clicking and dicken.
I personally don't care for knobs on a hunting rifle scope. Don't get me wrong I really appreciate my March scopes for Target work they do what I need and they do very well out to a thousand yards. But when you're talking about hunting I'll stick with what I recommended up top.
The Schmidts are built like tanks. Have second to none optics.Are first focal plane which gives you an edge in the dark. And if an unusual situation did occur where you needed to have service you send it to Virginia.

Only accurate rifles are interesting.
