I've always used the Sierra tables in the appendices of their reloading book to get a good idea of drop for various zero setups. IMO they're the best to figure out the trajectory of which bullet at what muzzle velocity for a given sight-in distance.
You can figure the muzzle velocity "close enough for government work" from the reloading tables, if you don't have a chronograph.
