I recently purchased a C Sharp Highwall that had a MVA 3000 on it. I took it off and put it on my Shiloh Sharps 45-100, 30 inch barrel. I do not have any literature on the scope and do not know what each mark moves it or what the size of the Mil-Dots are on the cross hairs. I am getting ready to go to range and want to be able to make some educated adjustments to get on paper. Any help would be appreciated.
