Yea its the one with BDC, when I first started looking there was a fellows review on the scope that was shooting same hole shots at 100, 2" at 200 and 4-6"at 250 holding dead on with the BDC he was shooting 150 of777 since then I have found that most shoot 100grain, I hope I haven't messed up and have a gun that likes 100 and a scope set up for 150. By the way it seems powder choices are leaning to 777 rather than pyrodex, any ideas why
