I'm firing 300 grain lead hard cast bullets at 2100 FPS out of my 45-70 1895SBL. I put my Leupold 2-7 scope on it using Burris Xtreme extra high rings (advertized as 1-inch high rings).
So the question...how do you figure out the scope height for ballistic programs when you want to calculate trajectory at a given range? Do I need to measure stuff or should it be published somewhere? If I need to measure, do I measure to the center of the scope tube or the bottom of it and to where on the rifle?
So, can you help me?
