[QUOTE="Rifleman97, post: 1546655, member: 103996"] Well that would depend on the ballistics, I’d you have a flatter shooting cartridge, it would fall less and therefor be closer to the crosshair than one of a slower bullet. For example (making up numbers here for simplicity’s sake) If you have one bullet moving at a speed that it drops 200 inches in 1000 yards, and another that drops 400 inches, because of the linearity of the slope relative to the crosshair, it would be twice as drastic of a change at that range. So for inches I thew in some made up numbers into a ballistics calculator for some perspective. I just said a 200 grain bullet with a velocity of 3000 FPS with a BC of .7 at 29.6 relative Hg/in 2500 feet at 20° With 50% humidity. (All just semi realistic numbers I just made up for sake of calculation) At 1000 yards the calculator said it would drop 236.5 inches. At .0175 inches off of parallel per inch, times 236.5 that would equate to roughly 4 inches off target. I could be using the wrong math here though because even though one degree isn’t much, I feel like it should be a bigger number than that. I’m going to do some research and get back to this thread if I find a mistake in my math. [/QUOTE]
