Im hoping some one might be able to help me out with this one. I've just got a MTC mamba 4-16x50 and want to calibrate it correctly. The manual I got with it only tells you the caliberation based on a mounted scope height based on 1.75" where as mounted on my air arms s410 .22 it sits at 1.26". I was thinking of using chair gun to do this but having watched one of si pittaways videos on YouTube he said they tried to use this to do Daves scope and it wasn't very successful. Any help welcome.
