I do realize you are talking about 2 different bullets and loads and I agree the 300 is the better bullet, I prefer heavier bullets myself. The point I was making is the adjustment to the sights is just that, to the sights. It should affect both loads in a similar manner. Adjusting any bullets impact at 100 yards will affect the POI by twice the adjustment at 200 yards, i.e. 1" at 100 is equal to 2" at 200 from a sight adjustment viewpoint regardless of the load.I based my estimates earlier on some approximations but they should be close enough to get you there for the 200gr bullet. Here is a chart that should get you close with the 300gr XTP.

Here is the same load adjusted up about 1" at 100 yards.

Here again with a 100 yard zero.

I hope this clears it up a bit for you.
