JSH, Bob S and garandsrus give excellent info. Many high power shooters, myself included, will have a load for the 200 and 300 yard line and then a different load for the 600/1000 yard line. This requires different zero for the different ammo at the different range.
That leads me to your next question/statement: "You adjust the load in the brass based on the distance to shoot, not to adjust the clicks on the scope."
At the ranges you mentioned in the first post (out to 700 yards) some very serious elevation/sight changes are necessary with cast bullets. I mentioned earlier that most scopes do not have the 57+ MOA adjustment to take you from a 100 yard zero to a 700 yard zero. It will not be feasable to "adjust the load in the brass based on the distance to shoot, not to adjust the clicks on the scope." You will indeed have to adjust the scope/sights even when going from 100 to 200 yards even with different loads.
As an example; I use the Lee 312-155 over 6.5 gr Bullseye to sort of duplicate the "Guard"load in my '03s. It runs 1120 fps and is very accurate and pleasant to shoot. I have been know to plink out to 500 yards with it using the ladder sight on the '03A1. The zeros for it are completely different than those for the previously discussed 311299. I also have used the 311299 for "cat's sneeze' loads as low as 300 fps which takes up a whole lot of rear sight elevation (most of it actually) just to zero at 50 yards.
It was suggested to KISS and use one load for your tactical matches. I concur as you will have enough "fun" tracking the different sight settings at the different ranges let alone tryimng to figure out correction for the wind.
