Depends on the load you're shooting. Off the top, I know 200 vs 225yrds in the 325grn leverevolution from my wife's rifle drops 7", so if I shot a dialed 200yrds over 200m, she'd probably fall 5" under. My 44mag with 300grn xtp's gets ~15" from 200 to 225yrds, so I'd miss by around 10" if I dialed 200 for a 218 shot. Of course, a standard bottleneck cartridge around 3000fps will only vary an inch or two, but he didn't say what he was shooting.
