You never have to measure the ogive if you don't want to. You can find the same sweet spot changing the OAL and recording results but you have to repete for every different brand/weight of bullet.
Then again thousands of sucessfull reloaders never bother with that either for one reason or another. For example if you use an autoloader and crimp in the cannelure, just load to said OAL. Nothing special needed.
