Lets say a given bullet drops 152" at 800 yards and 124 @ 750 yards.
Then add the 30 degree slope. 800 becomes 124" of drop. Yes the drop in inches is the same as 750 yards on a level plane. However if you treat it as a 750 yard shot using MOA youre going to be off. 124" at 750 yards = 15.75 MOA. 124" at 800 yards = 14.75 MOA regardless of slope. The inches of drop is the same between the two yes. The MOA used to compensate is NOT the same. The bullet's path changes due to the slope as you know. Those changes are not compatible with any distance other than the line of sight to target. You still have to figure your MOA from the inches of drop at the range fired. The MOA to inches of drop relationship is different for every range even if the inches of drop was the same from range to range.
I understand what youre saying about the scope being less than 25 MOA on the vertical plane when adjusted to 25 MOA on a slope not 0 degrees. This is not the issue. Regardless of slope, when youre looking at a target at 800 yards line of sight your scope when moved 25 MOA will move the reticle 25 MOA at 800 yards in relation to the target regardless of where the bullet impacts. When the bullet impacts at less drop than normal due to this slope you compensate accordingly. When the bullet falls 152" at 800 yards the appropriate MOA is 18.25. When it falls 124" the appropriate MOA becomes 14.75. The slope doesnt matter at this point. The slope dictates a bullet trajectory. Even though the slope will cause a bullet to drop less than a shot at 0 degrees the line of sight distance is NOT null and void for calculations. Line of sight is line of sight, inches are inches and the MOA at range is MOA at range.
I hope that helps.
Long range shooting is a process that ends with a result. Once you start to focus on the result (how bad your last shot was, how big the group is going to be, what your buck will score, what your match score is, what place you are in...) then you loose the capacity to focus on the process.
