Without the ability to calibrate the scope to your specific cartridge, and I mean whether it's a 30 gr or 50 gr bullet, it seems gimicky. I have shot many rounds out of my .22 mag and the drop difference between a 30gr Hornady and a 50gr Federal is approx 4-5 inches at 100 yards. I think it's just as important to spend a lot of shooting time with a rimfire gun to learn holdover for the cartridge you are using.
I tried shooting some 200 yard groups with my .22 mag this weekend. The drop difference between 100-200 yards with the 30 gr Hornadys was around 18 inches. Now it will be even more with the heavier rounds. A compensated reticle is only as good as your ability to judge or measure distance. And with a rimfire the drops are such that you would need to be pretty accurate.
IMO shooting time will help out more on a rimfire than any reticle.
