I'd suggest mounting a proper bull at 200yds, with an inverted one taped to the bottom of it, firing a couple of shots, and measuring - not guessing - how low you hit. Then, using your 100yd info, make what would seem to be an appropriate correction. That should put you on paper, and ready for fine tuning, though I don't suspect you will be happy with the results. A rifle that does 6" at 100yds. is not likely to do much better than 15"-18" at 200 - it's not exactly linear. I'll refrain from the lead discussion, respecting that you know your rifle FAR better than I do. - but that doesn't mean I agree with you. NO offense intended!
