I have the 220. I do not see a need for the 12. mine will shoot 3" groups at 200 yards. here is what is does at 100 yards.
killed 6 does with last year.
I posted this on another topic on here, but I killed the next to last morning of the season last year.
From looking at ballistics, I am not sure if it will kill at 200 yards but it will out to 150 yards. Killed a doe with it and left a great exit hole. Leupold 3-9 vx2 with lrd is a great scope for it. I a shooting 2-3/4 remington accutips,light recoil which is nice. 3" do not shoot any better.
