What's the difference?

adjusting target knobs is pretty simple actually, if you do your homework.
You mount your scope and sight in, then loosen up the set screws and raise the knob and put the graduated dial on "0".
then you make up a drop chart or you can run the velocity through a ballistic program.
Range your target and make your adjustment, the 6x18 loopy is .192 MOA per 100 yds to target per click. its alot simpler to just figure your comeups "clicks" at home and put them on your drop chart. then you just range, click, and shoot.
I've taken groundhogs to 550 yds with my 223, no way I could estimate a 40+ inch holdover.
On my big game rifles I don't adjust the scope till beyond 500 yds, its easier to just hold over
