Take a look-see at the Nikon Prostaff 22Rimfire 3x9 by 40mm BDC 150 scope. It has a fixed parallax of 50 yards, which means you don't have to worry about parallax at all for all intents and purposes. You have 3 bullet drop compensators below the + hair. Zero for 50 and you can use the Nikonnunter.com spoton program to print out your trajectory, velocity and hold over tables (which circle or part of the circle to use) out to 200 yards.
For practicality for a hunting scope, I stayed with the 4x with the Nikorplex reticule. With a 50 yd zero, depending which load I am using, for instance the Fed Lightning 510b, the top of the heavy post under the + hair is POI at 106 yards. 1.6 inches low (below the + hair) at 75 yards. I am not concerned with trying to hit tin cans at 200 yards, but getting a squirrel out to maybe 60 yards or so. The Spoton program will also calculate your flight path at 10 yard intervals for various velocities, bullet weights and manufacturers. You can also use the ballistics, weight, etc for you own favorite ammo, if you know it, and put it into the calculator.
Personally, I think the BDC is a lot of hype, especially for centerfire cartridges. The field of view, and thus the aim point changes every time the power of the variable scope in changed, and you need to carry an excell spread sheet with you and a laser range finder to figure out where to hold. By that time, the deer/elk/antelope is long gone. And with a 400 ft field of view at 350-400 yards, there is no +hair in the middle of the little circle to use. I like the mil-dot lines below the +hair/horizontal line better. JMO.
