Guys
I am over my head and need advice. I copied some stuff from some different websites on the Magnus and Coriolis effect. I remember the back site on the trapdoors was made at an angle to compensate for part of this. I know that it is not going to be 100% but. We have started making scope rings and I was wondering if because our scope rings have the bubble in them. If when you mounted it on your rifle and took a feeler gage and made sure the gap on the top cap on the left side was the same on the right side. Could you then take a pc of plywood at 100 yards and put a nail in the top portion and tie a string to this with a weight attached so it would be vertical due to gravity. If my 308 drops 39 minutes at 1000 could I drive another nail at 40.83” (39 x 1.047) then measure over to the left 1.1 moa (1.151) because of the data below. Drive another nail here. Now hang my string on this nail and with my bubble straight with the world, cant my scope to match the cant of the string. Would this delete “most” of the effect mentioned below? I
For example (typical 1000 yard small arms trajectory), if you always shoot in the northern hemisphere where the horizontal drift is always to the right, and you have a right twist barrel as most of us do, then your bullet will drift to the right approximately 9" due to gyroscopic drift, and an additional 2.5" due to Coriolis, resulting in 11.5" right drift, even in zero crosswind. (1moa = 10.47” 1.1 moa =11.51” this is my figures in parenthesis)
